In 2005, researchers cracked the code of the chimpanzee genome, providing a window into the differences between humans and our closest primate cousins. Science correspondent Jon Cohen has been following the DNA hunt, as well as new studies in ape communication, human evolution, disease, and diet. In Almost Chimpanzee, Cohen takes readers on a scientific journey behind the scenes in cutting-edge genetics labs, rain forests in Uganda, sanctuaries in Iowa, experimental enclaves in Japan, and even the Detroit Zoo.
