A population of Mountain Gorillas recently underwent a complete upheaval in the most central aspects of their gender-based social structures. If they can do it, so can we. … More What Mountain Gorillas Can Teach Us about Gendered Behaviors
(A long discussion of animal communication can be found in my book.) In the last 40 years, there have been many apes that have been taught to communicate with humans using sign language or other means, but the most famous among them are Koko the gorilla, Washoe the chimpanzee, and Kanzi the bonobo. These are … More Koko, Washoe, and Kanzi: Three Apes with Human Vocabulary
Science moves so fast in our modern era that we forget how young some scientific disciplines really are. Darwin founded evolutionary biology just over 150 years ago. Mendel did the same for modern genetics around the same time, although his work didn’t blossom (pardon the pun) until several decades later. The scientific study of animal behavior didn’t really … More The “Trimates,” The Founding Mothers of Primatology
In the study of human evolution, one conundrum has always vexed us: how did humans evolve such powerful brains? Few Differences in Chimp and Human DNA The genome of Homo sapiens is remarkably similar to those of our closest extant relatives, the common chimpanzee (Pan troglodytes) and the pigmy chimpanzee, or bonobo (Pan paniscus). On the sequence level, we … More Genes Found that May Explain Expansion of Higher Brain Function in Homo sapiens
It is readily apparent that humans are, by far, the most intelligent species on the planet. How this came to be, however, is anything but clear. Our substantial cognitive abilities are made possible by our enormous brains. When it comes to brain size (relative to body size), humans have the largest brains of any vertebrate. … More Is Violence What Made Humans Smarter than Other Animals?
