In a study appearing in Science Advances, researchers analyzed genetic samples from individuals who self-identified as South African Colored, a term denoting mixed ancestry. The researchers found that modern populations of this group in the Western and Northern Cape provinces retain majority Khoe-San genetic ancestry, exceeding 48%.

A genomic analysis of over 1,200 people from across South Africa reveals how colonial-era European, Indigenous Khoe-San peoples, and enslaved people contributed to the modern-day gene pool in South Africa.

Is it possible to find a common set of genes for regeneration, that could unlock a new understanding of this process? A comparison of the expression of thousands of genes from six animals found little evidence of a core conserved trait, but does point to some new areas to investigate.
