New research challenges the traditional belief that only men were hunters in ancient times. Physiological and archaeological evidence suggests that females also participated in hunting during the Paleolithic era. Estrogen played a significant role in their ability to engage in long-distance hunting. Neanderthal remains show a balanced distribution of bone injuries related to hunting. The myth of 'Man the Hunter' persists due to stereotypes and sexism. The rise of agriculture led to the separation of men's and women's work spheres, negatively impacting women.
