Rosati, A. G. (2018). The ape inside us: Chimpanzee behavior and human evolution. Natural History, 126, 34-36.[PDF] Abstract
Darwin noted that a major challenge for his theory of human evolution was “the high standard of intellectual powers and moral disposition” that our species has obtained. Yet Darwin was also a forerunner of the nascent field of comparative psychology—gathering observations of animals from animal breeders, his own pets, and primates in the London Zoo—and ultimately made a strong argument for continuity between human and animal behavior. This tension between how animals can both appear incredibly humanlike, but also sometimes quite alien, has long captivated scientists—along with anyone who’s ever pondered what’s going on in the mind of their pet.
