Some primatologists have argued that to understand human nature one must understand the behavior of apes. In the social interactions and organization of modern primates, the theory goes, that one can see the evolutionary roots of his own social relationships. One of the primary agents of genome evolution is gene duplication. Duplicated genes provide the raw material for the generation of novel genes and biological functions, which in turn allow the evolution of organismal complexity and new species. Collecting the DNA of humans, chimpanzees, bonobos, gorillas, and orangutans from blood and experimental cell lines, the researchers used microarray analysis to identify variations in the number of copies of individual genes among the different species.
