New Media  | 12 de febrero de 2009  | Vistas: 498

Based on her book Why Sex Matters: A Darwinian Look at Human Behavior, evolutionary biologist Bobbi S. Low explains the traits, biases, and preferences of sexual behavior in humans and animals.  Referring to behavioral ecology, and using specific examples from around the world, she describes how humans and other species are both similar and different. She also discusses the importance of understanding evolution in dealing with diseases, conservation, and sustainability.
