There is a “ghost” ancestor in the human genome
Deep learning allows scientists to "scour" the human genome, and leads to the discovery of a third ancestor besides Neanderthals and Denisovans. Who is?
Why did it take 20 years for the sequencing of the human genome?
Decades to get there, then finally in 2001 the sequencing of the human genome. Was it complete? No. Today, finally a complete sequence. Maybe.
