. . . and then takes some lumps

The skeletal diversity that many scientists use to divide up fossil species in our evolutionary past masks a genetic unity that actually encompassed relatively few species, contend researchers in an opposing camp.

Our family tree does the splits…

Large-scale changes in climate and habitats may have sparked the evolution of many new animal species in Africa beginning 7 million to 5 million years ago, including a string of new species in the human evolutionary family.

Early Brazilians Unveil African Look

Prehistoric human skulls found in Brazil share some traits with modern Africans, leading a Brazilian scientist to theorize that Africans rather than Asians first arrived in the Americas sometime before 11,000 years ago.

Fossil Skull Diversifies Family Tree

A 3.5-million-year-old skull found in Kenya represents a group of species in the human evolutionary family that evolved separately from australopithecines such as Lucy's kind in Ethiopia.
