“It’s about life” - Mark McAllister and the 2.0 Project

Monday, September 12th, 2005

Mark McAllister is a twenty-year-old man with Spinal Muscular Atrophy (SMA), a rare condition that causes the degeneration of motor neurons and the weakening and wasting away of muscle. In a wheelchair since age 3, McAllister is fighting the inevitability of his death: victims of SMA do not live much past 30 years of age. His fight is as epic as any told in human literature, but as personal as the questions each of us ask about the nature of our existence.There are the usual hopes for a medical breakthrough that will spare McAllister further deterioration in health. The effectiveness of using valproic acid and carnitine to treat SMA in children is currently in phase II clinical trial. “The results of the study won’t come for a while yet,” says McAllister, “but it looks more like a treatment than an actual cure.” Research into other genetic diseases and human genome research in general also provide promising avenues to discoveries that might have some bearing on SMA.

The question is, will treatments become available soon enough to extend McAllister’s life just a little bit longer, leading up to that wonderful day when SMA is cured forever? The prospects are improving, but McAllister understands the reality. “The push for a cure waxes and wanes depending on the funding available at the time.”

At age 16, McAllister learned just how fast his physical abilities could deteriorate. “I’ve always been in a wheelchair, but up to that point I had adequate use of both my arms, At this time, however, my left arm began weakening. The degeneration was alarming, and within a year and a half I had completely lost the use of that arm. This was the first event in a series that would ultimately leave me frailer than I had been before. It was at this time that my mortality became very apparent to me.”

Humans, regardless of their preexisting conditions, face a period near the end of their life when their body rapidly begins to fail them. Though it might seem a lot worse to live only 30 years with already limited physical abilities before dying, to some people of reasonable health, death at any age is a horrifying prospect.

McAllister discovered people with this view of death while exploring the philosophy of transhumanism. Horror of the finality of death has lead some to embrace this philosophy and its exploration of alternatives to oblivion or a supernatural afterlife. While a majority of people continue to believe that death is simply a natural part of a larger cycle involving birth and existence, transhumanists hope to overturn such thinking by showing that humans can, through science and technology, obtain physical immortality.

McAllister provides reasons why physical immortality could be positive. “First off, we live in a fast paced society that focuses on immediate gratification. This doesn’t provide a person much of a chance to explore their potential. In a world inhabited by immortals, we could see the rebirth of the ‘Renaissance Man’, with individuals mastering several disciplines. Second, immortality provides for the best chance at societal growth. For all intents and purposes we hit the reboot button with each generation. Sure, society does evolve over time, but every generation basically starts with a blank slate. Image what would happen if we had leaders with centuries of wisdom and experience. Society would grow,learning from mistakes experienced on its own instead of learning from history texts.”

Recent scientific research indicates we might be heading rapidly toward just such a world. Unfortunately, for many with preexisting conditions, this progress might not come soon enough. The plight of actor Christopher Reeve, who suffered an accident that left him without the use of his body below his neck and who became an outspoken advocate for cutting-edge medical research, comes immediately to mind. He remained hopeful for a breakthrough within his lifetime, but he did not live to see the announcement by South Korean scientists late last year that they had used adult stem cells to allow Hwang Mi-Soon at 37 years of age to walk again after 20 years of paralysis.

What does one do when future treatments and cures are tantalizing out of reach and every day is a race against time? To transhumanists and other technology progressives, cryonics offers one possible solution. Cryonics is a speculative technology used to freeze or vitrify the human body after clinical death for indefinite storage. If the body can be vitrified soon after death - thereby halting or slowing down significantly the process of decay - then maybe it can be held in indefinite stasis until future technology has progressed far enough to cure, repair and revive the individual. Although those few people who have paid for cryonics plans generally agree that the chance of their resurrection is low, they feel it is a fair gamble. After all, once they are clinically dead, they have nothing else to lose, and everything to gain should their slim hopes be realized.

Alcor and the Cryonics Institute, the two primary facilities for cryonics in this country, allow members to use a life insurance policy as payment, along with annual fees. Upon clinical death, the member’s insurance policy is signed over to the cryonics facility. For many people, this is their only option, as full-body internment at cryonics containment facilities can cost as much as US$100,000, before annual fees are added in. A neuropreservation plan that retain only the head and brain still costs up to US$80,000.

Some people cannot get enough insurance to cover the cost of cryonics preservation. McAllister is an example, a person with a preexisting condition not covered by most life insurance plans. Any life insurance policy he might qualify for will come with particular limitations and may not be large enough in value to cover the cryonics costs. Without a life insurance policy of sufficient value, McAllister must raise the money to pay for this service upfront.

Enter the 2.0 Project.

Conceived by McAllister while reflecting on his options after not winning a lottery, the 2.0 Project serves dual purposes. The first is to raise enough money to let McAllister sign up for a cryonics plan, and the other is to raise awareness about transhumanism, physical immortality, and the plight of the uninsured and uninsurable in a world of rapid life extension. McAllister argues that ultimately “the 2.0 project isn’t about me, it’s about life.”

The 2.0 Projects hopes to raise US$130,000 to cover Mark’s neuropreservation at Alcor as well as other expenses including the cost to move near their facility in Scottsdale, Arizona, USA, from his current residence in Canada, and living and medical care costs should Mark’s health take a drastic turn for the worst. To date, with a mix of donations and McAllister’s own personal financial contributions, the 2.0 Project has raised US$443.06 on word of mouth alone.

McAllister is also trying to build a team of graphic, industrial, environment, interior and other designers and artists to help turn the 2.0 Project into “a giant communications project.” McAllister’s own work in graphic design has been supported by the use of technology to augment physical abilities limited by SMA. “Computers have been a blessing for me,” he explains, “and I wouldn’t be in this line of work without them. My drawing skills can be a bit sketchy (no pun intended) at times, but I still have enough strength in my right arm to carry out my job.” Knowing through his work the potential impact of design on society, politics and individuals, McAllister and his team will create a visual language for disseminating and leading discussion about technology progressive ideas.

Because the 2.0 Project is informed by transhumanism, it faces its own obstacle of image. There is already a growing backlash against technology progressive philosophies, led by some of the leading bioethicists in the United States, in addition to religious and conservative interests. When Foreign Policy asked invited writers in its September-October 2004 issue what they believed the world’s most dangerous ideas were, Francis Fukuyama, a member of The President’s Council on Bioethics, Professor of International Political Economy at Johns Hopkins University’s Paul H. Nitze School of Advanced International Studies, and author of several books critical of future progress, responded that it was transhumanism. The coming transformation of modern humans into transhumans with enhanced abilities enabled by science and technology led Fukuyama to wonder “what rights will these enhanced creatures claim, and what rights will they possess when compared to those left behind?”

When asked about possible criticism leveled at the 2.0 Project, McAllister states that “[d]eath is a major concern for everyone on this planet, whether they like to admit it or not. Every world religion has come up with its own answer to death. In fact, I believe that at the core of all religious belief lies the fear of death. So really, seeking immortality through science is no different than seeking it through spiritual means. The only hitch is when people can’t see past their own paradigm. I understand those who would feel adversely towards the 2.0 Project, and I respect their viewpoint. It’s impossible to get everyone to agree on something (especially the concept of death), so room must be made for different beliefs and opinions.”

The pursuit of immortality through supernatural and mystical means, our myths of eternal human-like gods, the latest diet craze, Botox - each is another way that humans try to hold on to their existence just a little bit longer, a desire that is at least as old as recorded human history. But the idea that there is no set limit to human lifespan is as new as the breakthroughs being reported in the scientific literature on a nearly daily basis. Biology tells no lies, but it tells a difficult truth. With each result, we are forced to rethink what we thought we knew about our existence and destiny.

When the research stopped being speculative and began to produce measurable results, critics that had previously called the entire endeavor “science fiction” and a waste of time and money immediately began calling for limits and outright bans, culminating with suggestion by Leon Kass, another member of the President’s Council on Bioethics, and others that people who live too long might need to be euthanized for the sake of society, regardless of their level of health. A rapidly growing population of centenarians, many of them now in their eleventh decade, might argue otherwise.

Through the 2.0 Project, McAllister hopes to encourage further discussion about these issues within the transhumanist movement and beyond. He says that he does “consider myself a transhumanist, but I use futurist to describe myself just as often. I’m not one who cares much for labels, and futurist is a bit more generalistic. I do, however, use transhumanist on the website for the simple fact that I consider myself a transhuman. I’m an individual in transition, whose ultimate goal is posthumanity (whatever that turns out to be). Whatever form it may take in the coming years, I believe this to be the core of transhumanism. All other facets are negotiable.”

It is this human face on topics unfamiliar to most of the public and frightening to critics that may be the 2.0 Projects strongest asset. McAllister dreams find flight beyond a cure for SMA and a rejuvenated body. He envisions a bright future of possibilities available to everyone, regardless of their current status.

“Transhumanism is an optimistic philosophy. Likewise, the 2.0 Project is an optimistic mission. My philosophy is based largely around transhumanism, thus the project is based largely around transhumanism. I don’t want this to sound like it’s just for technophiles though. Above all else, the project is about life. I’m hoping that this will appeal to people of various philosophies.”

Technical Diving from Florida to Cyberspace

Sunday, July 10th, 2005

Cristian Pittaro is a diver, but if you are picturing a guy with gear on his back diving the sunlit open waters of the ocean, then you have it all wrong. Pittaro is a technical diver, the kind of diver that should inspire awe in us mere humans. His diving destinations include shipwrecks and underwater caves, some of them at depths that require helium in the breathing gas and decompression stops on the way back up. A new Internet-only video channel has been launched called the “Technical Diving Channel” that includes video captured by Pittaro during several of his dives.

Started by an Internet host that specializes in providing services for diving websites, the Technical Diving Channel can be found on Shoutcast TV, through the Winamp audio and video player. Shoutcast itself is free server software that brings television distribution to the masses and a number of early adopters are broadcasting everything from anime to adult material to pirated television series over the Internet. A healthy number of legal and interesting specialty channels have begun to appear, including the Technical Diving Channel.

Claustrophobic caves and ghostly shipwrecks emerging from murky depths might not have the same impact over the Internet that they do during the actual dive, but the diving videos on the Technical Diving Channel allow the audience to experience the thrill of ocean exploration, led by the enthusiasts that head there regularly. The videos on the channel are provided by Pittaro and a growing number of other technical divers.

Pittaro taught diving for several years in a local dive club in the city of Rio Tercero in the province of Cordoba in Argentina before becoming a professional diving instructor for an international agency. He moved to Florida in the United States and began technical diving around 2001. After his move, he created the “Neptuno’s World” website about caves and shipwrecks for divers and non-divers alike. The site also included GPS positioning information of interesting locations for other divers.

“Then I joined a technical diving forum called The Deco Stop,” says Pittaro, “and they started hosting websites to help support the forum. [.] I had a good deal from them, [with] plenty of bandwidth to show my photos and videos and space to store them, so I took it and [that] is how neptunoworld.com [was] born in 2003.”

When Robert Mayer, a student of Pittaro’s wife (who is a diving instructor and also a fellow technical diver) asked if he could use their diving videos for a 24/7 channel on Winamp, Pittaro thought it was an excellent idea. “Lots of people now [are] porting their videos to Robert’s project. [H]opefully [the channel] is going to be a place with tons of different videos that will keep people stuck there all day [while] amusing others that for any reason can’t dive.” Pittaro hopes that it will let the audience’s “imagination fly a bit.”

Technical diving, according to Wikipedia, is “a form of SCUBA diving that exceeds the scope of recreational diving. Technical divers require advanced training, extensive experience, and specialized equipment.” Technical diving also requires the diver to pay attention to a lot of different things, even before adding a video camera to the mix. Pittaro says that “in tech diving or cave diving you need to be very focused, you are already very over-tasked looking at your time, your depth, the current, your buddy, your gas, drysuit, you have lots of gear, deco bottles, flashlight, scooter, and [the list] goes on and on.” Trying to film a dive requires even more care. “[Y]ou can’t be making a video and kicking the silt in your back that could be fatal for you or somebody else if the water inside the cave turns [into] a ball of mud.”

While some may consider this activity dangerous, to Pittaro danger is relative. “I can’t work in a nuclear reactor if I don’t know anything about it,” he explains, “because [it] is more likely I’ll make it blow away and kill myself and put others in danger or even kill them. Cave diving is about the same, there are some levels risks on it, like silt, no direct access to the surface, no light, very complex tunnels systems and many others, but that is why we get trained [.] and get the best gear we can get, because all that is going to be what keeps us alive in there.”

“Cave diving isn’t dangerous,” he continues, “if you have the appropriate level of training for the dive you want to do. [.] You need to build up experience progressing from simple dives to more complex. [Y]ou can’t just do a dive 3000 feet inside the cave after your first cave certification; you need maybe several years of cave diving to go there safely.”

Cave diving provides an interesting perspective on these little-explored environments. “Caves are very special in every point of view,” says Pittaro. “They are [.] very fragile environment[s] that need a lot of care. Diving them, taking videos and pictures help me and hopefully others to understand them and to see how fragile and nice they are and how to preserve them.”

While cave diving is mostly about exploring and appreciating new environments, shipwreck diving is a unique way to explore history while paying respect to those who may have lost their lives during a battle or an accident. Sometimes technical divers discover something about a shipwreck that corrects the history books. The ship might have found its final resting place somewhere other than recorded, or sometimes it “is easy to tell that the wreck didn’t sink in the way the history said; for example one that [was] supposed to be broken in half and when you go and see it, [you] find it all intact and [in] one piece.”

Technical divers can be a close-knit group of enthusiasts. Pittaro met his future wife Lesley soon after they both started technical diving. They kept running into each other, became friends, and “we teamed up often when going out diving.” Pittaro says about their marriage: “If I can trust my life [to] her on a dive I thought it would be safe to marry her.” Neptunoworld includes a section that chronicles their several honeymoons together exploring new destinations, some of them actually out of water.

As the Internet continues to mature as the major distribution network for entertainment and educational content, expect new specialty channels to emerge. Content like the Technical Diving Channel allows the world to share in the sights and sounds of frontier destinations, captured by real explorers. Pittaro plans to continue documenting his dives with images and videos and make them available over the Internet.

What happens if Pittaro becomes too old to dive?

“I can [sit on the] couch with my wife and watch our own life on TV, [.] remember all those incredible places we had been, [and] maybe share it with new family members.”

An Interview with Becca Walker

Thursday, April 28th, 2005

Gender issues such as the role of women in science and technology were brought to a head recently when Lawrence H. Summers, president of Harvard University, suggested at an academic conference that intrinsic differences between males and females may explain why there are fewer women in science, mathematics and engineering. Summers, according to his defenders, intended his statement as merely one of several hypotheses to explain this obvious and little researched discrepancy.

I recently interviewed Becca Walker, a geosciences graduate student at the University of Arizona, and I asked her why she thought gender is still even an issue. “You tell me,” she laughed while shaking her head. “I think one of the things that’s being investigated right now is why the gender ratio in graduate programs is essentially 50/50, and actually even leaning now more toward women, but when you look at who is getting these academic positions, women compose, you know, a very small minority.” While there seems to be no obvious answers, Walkers suggested further research might be helpful, such as surveys and interviews with faculty members, staff members and graduate students from various colleges and universities about their perception of these gender issues in academia. “I think there needs to be a lot more consideration of this issue.”

In the geosciences, Walker says she has not faced explicit sexism while a graduate student, although she knows of other women who have. She believes she was able to prove herself as a woman in geosciences by being physically fit and keeping up with “the guys.” She expects these issues to be more difficult for women graduate students as they attempt to enter the work force when their education is complete. “One of the major issues is, if you’re applying for a tenure-track position, what about children? […] Is it possible to do cutting-edge research, do excellent teaching, have a service component, and have a family? […] If you have a child, I mean, that is a major chunk of your time budget.”

Facing Challenges

If anyone is up to the challenges that these issues present, it is Becca Walker. In 2003 she was diagnosed with hepatitis, likely brought on by a soil microbe she caught during field work or other outdoor activities. “It’s probably a microbe that everyone in the population gets exposed to, but for some reason my immune system reacted really strangely to it.”

Although she was able to recover from the hepatitis quickly, her immune system also attacked and destroyed her own bone marrow. She was not a good candidate for a bone marrow transplant so doctors turned to immunosuppressive therapy. This therapy purposely killed her immune system in the hope of also killing off the particular cells that were attacking her bone marrow. After the therapy, her immune system and bone marrow needed time to grow back, but challenges remained. Becca had to protect herself from illness until her immune defenses returned. She took time off from school for treatment and recovery.

Walker is still in recovery, but she has returned to school with a vengeance. “I think that being back here and teaching and getting back into my research was one of the most important elements in my recovery.” It may be too dangerous for her to return to outdoor field work, but she has found a different environment to research: kindergarten through 12th grade classrooms.

Scientist/Teacher Partnerships

Many K-12 teachers instruct courses on subjects in which they have no formal training. To address this issue, several programs around the country partner scientists and other specialized experts with teachers to enhance the teachers’ abilities and knowledge in the natural sciences, technology, and mathematics. In return, scientists can come away with more effective teaching skills.

The “Collaboration to Advance Teaching Technology and Science” (CATTS) program is “a partnership between the University of Arizona and local school districts to improve science, mathematics and technology teaching at all levels” according to the CATTS website. This unique program brings CATTS fellows from the University of Arizona into K-12 classrooms. The working theory is that teachers will learn from the research experience of scientists, and scientists will learn from the pedagogical experience of teachers, benefiting school children in the process. While programs such as CATTS are created with the best intentions, not all scientist/teacher partnerships are successful.

Walker has been researching these partnerships to look for those factors that lead to success, and those that do not. She has spent time in K-12 classrooms observing scientist and teacher interactions. She also collected journals, conducted surveys, and interviewed the participants. In her research Walker has identified successful partnerships as being marked by specific shared goals, expectations, and labor; well-defined roles; equality; good communication, and an honest investment in learning from and teaching each other. She recently presented her results at GeoDaze 2005, an annual symposium at the University of Arizona of undergraduate and graduate research.

When partnerships failed, Walker found that negative factors such as intimidation and lack of communication were involved. For example, teachers were sometimes intimidated by the scientists, while poor communication regarding goals and roles led to confusion and conflict. Walker observed fellows that focused on teaching the students rather than the teacher. She also observed teachers who took breaks and conducted unrelated work while the fellow was left to lead class lessons alone.

Fortunately, even these ineffective partnerships could be turned around if negative factors were recognized and the partners invested their time and effort to resolving their differences. Sometimes it was as simple as someone finally speaking up. Walker described one situation in which the fellow approached the teacher and expressed his frustration with her lack of involvement and the need for them to plan their lessons outside of class. “He hadn’t communicated that need up until that point, and when this teacher realized ‘oh, […] I didn’t think this was one of the important criteria for us working together. Of course I’ll set aside time,’ the partnership evolved very successfully after that. So it’s definitely…it’s possible to overcome the majority of these barriers as long as there is honest communication about what needs to be changed.”

The work Walker has done is also applicable to the relationship between scientists and the general public. She hopes that her work will highlight these issues for scientists, teachers, and the public alike, leading to more effective partnerships in the future.

Looking Ahead

As for her own future, Walker will soon have a Masters degree and will eventually pursue a Ph.D. She plans to continue teaching and conducting research, including a possible return to outdoor field work. “I think that the further away I get from this illness, I might be a little bit more ballsy and decide, you know, I’m really going to have to be more careful, but I’m going to re-initiate doing field work.”

Which leads me back to my original question…why is gender still even an issue? With grace, intelligence, and passion, Becca Walker belies any suggestion that intrinsic differences between males and females explain why there are fewer women in academic positions.

An Interview with Geologist Jay Quade - Page 1

Monday, March 21st, 2005

The Desert Laboratory sits on Tumamoc Hill overlooking the city of Tucson, Arizona. Rainfall amounts here have been above normal this winter and the desert is in bloom. I am sitting in the office of Dr. Jay Quade, from where the view of both Tucson and the desert is spectacular. A faculty member in the Geosciences Department at the University of Arizona, Dr. Quade has recently returned from his latest trip to Ethiopia with samples of tuff - a rock of compacted volcanic ash barely distinguishable from soil - important for dating sedimentary layers in the region. Why does the tuff need to be dated? Somewhere between layers of datable tuff lies the dates of important events in the origins of modern humans.

With a climate similar to Tucson at its warmest, Gona Western Margin in the region of Afar in Ethiopia on the African continent has become a hot spot for scientists looking for fossil evidence of hominids, those evolutionary precursor primates related to modern humans. Dr. Quade is a member of the expedition that recently announced in the journal Nature the second discovery to date of fossil remains of Ardipithecus ramidus. This species may be one of the last common ancestors of humans and chimpanzees.

“I know “ramidus” means “root” in the local Afar language,” explains Dr. Quade, “and that’s the basic idea…is that this is near the base of the human tree, in fact, down in the root system somewhere.” The sample data used by the team for their Nature article “Early Pliocene hominids from Gona, Ethiopia” suggests the fossils are nearly 4.5 million years old. This is significant because around that time the hominid branch splits, leading to chimpanzees and modern humans. In fact, Ardipithecus ramidus has both human and chimpanzee characteristics.

“If you were to encounter these creatures in the street today, they’d look like apes. You’d say ‘that’s an ape,’ except for one thing…there is some evidence that they were bipedal - in other words, upright walking.” That bipedal ability is shared with modern humans. However, Ardipithecus ramidus likely had the brain size of modern chimpanzees.

Dr. Quade was asked to join the research team in 1999 during a panicked telephone call. The original geologist was no longer available. With the expedition about ready to begin, Dr. Quade agreed to head for Ethiopia. He brought to the team the ability to work with fine layers of sediments and trace these layers over long distances, in order to find samples that can be dated by current dating procedures. He also had experience in reconstructing paleoenvironments from the little evidence available in the geologic record. As the team began to explore As Duma in Gona, Dr. Quade was able to point the way to promising sites. Should interesting fossil fragments be found, he could then help restrict their age.

Why Ethiopia? “It’s clear that Africa is the cradle of mankind. When you look at the fossil record within Africa and then outside of Africa for, say, the Pliocene period, 4.5 million years ago, or 6 million years ago, the late Miocene, our antecedents are showing up in deposits in Africa, and mostly in Ethiopia, and they’re not showing up outside of Africa. So we know that Africa itself is the cradle, but we don’t really know where. You have to keep in mind that Ethiopia is famous for its fossils not necessarily because that’s where man developed, down in the Ethiopian Rift, in these big river valleys that occupy the Ethiopian Rift, but it is were they’re preserved.”

The geologic record is preserved in the basin formed by the rifting of Ethiopia. The land is being ripped apart by tectonics, and in a few million years the Red Sea will intrude further into the African continent. There are plenty of rivers in the region to deliver sediments to lower lying areas. The fossil fragments found tend to be in sediments deposited near lake shores. (Go to Page 2.)

An Interview with Geologist Jay Quade - Page 2

(Continued from Page 1.) Meanwhile, volcanoes in Ethiopia lay down layers of ash, pumice and other fragments through frequent eruptions. As this material begins to cement over time, it becomes tuff. Tuff sticks out from other layers because it is so light in color. The river and volcano activity are preserved in the varying layers of sediments that make up rock sequences in the region. In the background image the tuff is visible as light tan layers and the sequence is capped by a dark layer of basalt. Researchers can start to build a chronology of events by analyzing rock layers above and below the layer that contains fossil fragments from Ardipithecus ramidus, thus narrowing in on an age for the fossils.

Two types of absolute dating were of particular importance for this research. Samples of tuff from layers above and below the discovered fossil fragments were dated using radiometric dating, specifically Argon-40/Argon-39 dating. While the ash itself cannot be dated using this technique, ash nearer volcanoes may contain tiny plagioclase (a mineral) crystals that formed when magma spewed by the volcano rapidly cooled, trapping a particular amount of potassium inside individual crystals. Over time some of this potassium decayed into argon. By measuring the amount of argon to original potassium, and knowing that the decay rate is constant, an age can be determined for the sample. (This process is described in more detail in “An Interview with Geologist Jay Quade - Tools of Time.”) Combining the radiometric data with paleomagnetic data (also described in “Tools of Time“) Dr. Quade’s team was able to determine that the Ardipithecus ramidus fossils are between 4.51 and 4.32 million years old.

The article in Nature is not the end of story. While he could not speak specifically about what has been found, Dr. Quade indicated that his recent trip back to Ethiopia was fruitful. “There is much more complete evidence now. Various groups have found it but it’s unpublished. So stay tuned. […] It’s an ongoing story and there’s a lot happening.”

While the story about human origins continues to unfold, Dr. Quade is continuing other lines of research, including refining the use of the geologic record to reconstruct ancient climates and environments and studying the Atacama Desert in Chile as a Mars analog.

A few million years of evolution have led us from Ardipithecus ramidus trying to survive the violence of the Ethiopian environment to Homo sapiens sapiens - modern humans - also trying to survive the violence of the same region (see “An Interview with Geologist Jay Quade - Geology, Famine and War.”) But there is a huge difference between these two species, evident in the professional and personal passion of scientists like Dr. Quade. Modern humans also return to Ethiopia to sift through rock fragments and study rock layers because they are passionate about their interests and curious about our origins. We reconstruct our past to build a better future by using our higher brain functions, a result of the sometimes violent evolution of the primate family, to pursue knowledge.

The beckoning fossil fragments have something to tell us. That we listen is the direct result of evolution at work. Our response to this new knowledge will indicate where humanity is heading.

An Interview with Geologist Jay Quade - Geology, Famine and War

Monday, March 21st, 2005

Embarking on a geology expedition might sound exciting or boring, depending on your interests. However, there is more going on behind the scenes than just scientific research. Sometimes scientists find themselves in the middle of suffering and violence, and they begin to question why they are there, even as their heart reaches out to those in need, or as they work while gunfire is heard too close for comfort.

Ethiopia is a country where climate cycles lead to prolonged periods of drought. This and ethnic and religious differences often lead to tribal clashes. The result is human suffering and death. I ask Dr. Quade about how research into ancient hominids is helpful to society and individuals, in the face of such hardship.

“[...] you go to a place like Ethiopia,” he answers, “and I often ask myself this question - surrounded by famine, people are suffering - ‘Why am I doing this? Why are we pouring…this is money from the National Science Foundation of the US and the world.’ What we actually should be doing is feeding these people.”

But there is something about this research that interests a lot of people, even those most at risk of suffering. “It tickles a nerve. It tickles an intellectual nerve. We want to know where we came from. People are fascinated with that question. And I think that’s fair.” Many of the Ethiopians that researchers come into contact with agree. “They are fascinated as well,” says Dr. Quade. “They are caught up in the fever as well. They understand what these things [hominid fossils] are. […] They are getting at the roots of our origins.”

Some members of the Afar Tribe helped the research team search for fossils, but they carried weapons with them, as the Afar Tribesman in the image on the left demonstrates while holding an AK-47 against his shoulder. At one point during an early expedition, the team continued working while military escorts held back rebels making their way through the region. War does not recognize the scientific research site as a separate zone of nonviolence.

In Ethiopia, where the geologic record is tempting scientists with a treasure trove of fossils, the logic of science runs head on into the illogic of famine and war. The best in people is in conflict with the worst. Perhaps the common thread of curiosity about our human origins through people otherwise in conflict might be the foundation on which to build a more accommodating and peaceful future.
