Humans’ Ancestral ‘Homeland’ Traced to Northern Botswana
Africa has long been known as the cradle of life, but the exact location of our evolutionary breakthrough has evaded researchers – until now. In a stunning development, a study released Monday reveals that our ancestral homeland lies buried within an arid region in northern Botswana.

Adapting to higher altitudes gave the people in the Andes Mountains an advantage most inhabitants of the “New World” unfortunately did not have: They were able to avoid being completely wiped out by the diseases of European colonists, according to a new genetic study of people in the region.

Decoded Genome May Help Tortoise Win Survival Race
A “slow and steady” adaptation to evolving hazards will not save the Mojave Desert tortoise from extinction, and to save the endangered iconic species researchers have decoded the tortoise’s genome to identify specific genes that will guide conservation efforts and improve its likelihood of survival.
