New research shows that even people who don’t speak a native language can maintain a genetic identity even without it.
It turns out that the Kalahari and Namib Desert peoples have maintained their distinctiveness even without their native tongue.
This finding may be due to, among other things, a desire to keep pace with the speed of evolution.
Southern Africa holds possibly the greatest human genetic diversity, and new research reveals that it is in better shape than previously thought.
The study uses a combination of genetic and linguistic analysis to explore the relationships between Angolan Namib dwellers.
They find the biggest genetic differences between populations with contrasting lifestyles.
The authors speculate that much of this local variation and global eccentricity was caused by genetic drift . .
