Darwin's Legacy: Scenarios in Human Evolution compares ideas about human evolution Darwin published in The Descent of Man in 1891 to 30 scenarios about the evolution of such unique human characteristics as bipedalism, hairless skin, secondary sex characters, language and culture that anthropologists and psychologists published between 1950 and 2006. It evaluates ideas about hunting and scavenging, aimed throwing, primitive warfare, aquatic life, courtship, and sign language in light of modern data on genetics, stone tools, fossils, and primate behavior. Parallels between Darwin's ideas and those of modern researchers are striking.
