In 1994, a Swiss biologist named Pascal Gagneux began a Ph.D. program in zoology. His research plan was to stalk populations of wild chimpanzees in Cote d’Ivoire and Mali. Specifically, Gagneux was in search of chimp nests in forest trees. After he figured out where the chimps slept, he’d wait until they left during the day to search for food before climbing trees to collect their hair. Gagneux’s aim was to document genetic diversity in our nearest, dearest, and critically endangered relatives. In order to see what made one chimp different from another, and one population of chimps different from the next, he needed to be able to take that hair he’d collected, extract DNA from its follicle, and quickly multiply the DNA. If Gagneux had embarked on his quest just a few years earlier, that (...)
