PBS Human Spark Episode One: On Becoming Us

A major focus of this episode is the differences between Neanderthals and homo sapiens. This episode was initially shown on TV in January, 2010. Until an April, 2010 paper, the preponderance of evidence suggested that the Neanderthals were an evolutionary dead end, dying out when confronted by a wave of homo sapiens migrating out of Africa. Whether or not modern humans are directly descended from Neanderthals has gone back and forth since the dawn of anthropology. The anthropologist, Carlton Coon (1904-1981), has theorized that at least some human groups carry varying amounts of Neanderthal genes. Recent work suggests that the genes of many human groups are about 1 to 4% Neanderthal.
