Restless Genes [A] The drive tо see whаt lies beyоnd thаt fаr hоrizon or that ocean or this planet is a defining part of human identity and success. Not all of us ache to ride a rocket or navigate an endless sea. Yet, as a species we're curious enough and fascinated enough by the prospect to help pay for the trip and cheer at the explorer's return. Yes, we explore to find a better place to live or acquire a larger territory or make a fortune. But we also explore simply to discover what's there. [B] "No other mammal moves around like we do," says Svante Paabo, a director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, where he uses genetics to study human origins. "We jump borders. We push into new territory even when we have resources where we are. Other animals don't do this...In just 50,000 years, we covered everything. There's a kind of madness to it. Sailing out into the ocean, you have no idea what's on the other side. And, now, we go to Mars. We never stop. Why?" [C] Why indeed? Paabo and other scientists examining this question are themselves explorers, walking new ground. They know that they might have to rethink their ideas at any time. They know that any ideas about why we explore might soon face revision as their young disciplines turn up new evidence. Yet, for those trying to figure out what makes humans tick, our drive to explore is an exciting subject. What gives rise to this "madness" to explore? What drove us out from Africa and on to the moon and beyond? [D] If we are born with a drive to explore, perhaps the reason lies within our genes. In fact there is a variant of a gene called DRD4, which helps control dopamine, which is a chemical important in learning and reward. Researchers have tied the variant, known as DRD4-7R and carried by roughly 20 percent of all humans, to curiosity and restlessness. Dozens of human studies have found that 7R makes people more likely to take risks; explore new places, ideas, foods, relationships, drugs, or sexual opportunities; and generally welcome movement, change, and adventure. Studies in animals suggest that 7R increases their taste for both movement and new things. [E] Several studies tie 7R to human migration. The first large genetic study to do so, led by Chuansheng Chen of the University of California, Irvine in 1999, found 7R more common in present-day migratory cultures than in settled ones. A larger 2011 study supported this, finding that 7R, along with another variant named 2R, tends to be found more frequently than you would expect by chance in populations whose ancestors migrated longer distances after they moved out of Africa. Neither study necessarily mean that the 7R form of the gene actually made those ancestors especially restless; you'd have to have been around back then to test that idea with certainty. But both studies support the idea that a nomadic lifestyle selects for the 7R variant. [F] Another recent study backs this up. Among the Ariaal people in Africa, those who carry 7R tend to be stronger and better fed than those without 7R if they live in nomadic groups, possibly reflecting better fitness for a nomadic life. However, 7R carriers tend to be less well fed if they live in villages. The variant's value, then, like that of many genes and traits, may depend on the surroundings. A restless person may do well in an environment that often changes, but have trouble in a world where everything stays the same. [G] So is 7R the explorer's gene or adventure gene, as some call it? Yale University evolutionary and population geneticist Kenneth Kidd thinks that exaggerates its role. Kidd speaks with special authority here, as he was part of the team that discovered the 7R variant 20 years ago. He thinks that many of the studies linking 7R to a nomadic life suffer from bad methods or math. He notes, too, that the large number of studies supporting 7R's link with these traits is countered by another large number of studies showing no link. [H] "You just can't reduce something as complex as human exploration to a single gene," he says, laughing. "Genetics doesn't work that way." [I] It would be better, Kidd suggests, to consider how groups of genes might lay a foundation for such behavior. On this, he and most 7R advocates agree: Whatever we ultimately conclude about 7R's role in driving restlessness, no one gene or set of genes can make us want to explore. More likely, different groups of genes contribute to multiple traits; some allow us to explore, and others, with 7R quite possibly among them, press us to do so. It helps, in short, to think not just of the drive to explore but of the ability and not just the motivation but the means. Before you can act on the drive, you need the tools or traits that make exploration possible. Which of these sentences might Kenneth Kidd agree with?
