These baboons borrowed a third of their genes from their cousins

Genetic analyses of baboons in Kenya reveals that most of them carry traces of hybridization in their DNA.

Fifty years of observations turned up no obvious signs that hybrids fare any worse than their counterparts. But the new findings suggest that appearances can be deceiving.Genetic analyses of baboons in Kenya reveals that most of them carry traces of hybridization in their DNA.
