🔴 **A structured coalescent model reveals deep ancestral structure shared by all modern humans**

_“Using cobraa, we present evidence for an extended period of structure in the history of all modern humans, in which two ancestral populations that diverged ~1.5 million years ago came together in an admixture event ~300 thousand years ago, in a ratio of ~80:20%.”_
