Human evolution, the process by which human beings developed on Earth from now-extinct primates.Viewed zoologically, we humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago. We are now the only living members of what many zoologists refer to as the human tribe, Hominini, but there is abundant ...

Dunbar's number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships—relationships in which an individual knows who each person is and how each person relates to every other person. This number was first proposed in the 1990s by British anthropologist Robin Dunbar, who found a correlation between primate brain size and average social ...

During human evolution, individuals interacted mostly within small groups that were connected by limited migration and sometimes by conflicts. Which preferences, if any, will prevail in such scenarios? Building on population biology models of spatially structured populations, and assuming individuals' preferences to be their private information, we characterize those preferences that, once ...

According to Pulitzer Prize-winning biologist Edward O. Wilson, groups are the driving evolutionary force of the human species. It’s the cooperators, the team players who set aside selfish desires for the good of the group, that outcompete groups of non-cooperators and ensure their genes are passed on to future generations.
