Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.

  1. Climate

    Globe’s non-Africans all descend from a single move out of Africa

    Look back far enough and everybody’s ancestors were African no more than 72,000 years ago. Climate scientists would up that date to perhaps 100,000 years ago.

  3. Fossils

    ‘Cousin’ Lucy may have fallen from a tree to her death 3.2 million years ago

    A contested study suggests that Lucy, a famous fossil ancestor of humans, fell from a tree to her death.

    The first farmers were two groups, not one

    The humans that began farming 10,000 years ago in the Fertile Crescent may have been two cultures living side-by-side.

    Wolf species shake-up

    A genetic study says red wolves and eastern wolves may really be mixtures of coyotes and gray wolves, not distinct species.

    The turning of wolves into dogs may have occurred twice

    The process of turning wolves into dogs, called domestication, may have occurred twice — in the East and the West — ancient DNA suggest.
