|Kamilah the gorilla|
The full genome of Kamilah, a female gorilla from San Diego zoo, has been sequenced. With this one all extant great apes, excepted the bonobo, have been fully sequenced.

The authors propose a divergence of Gorilla from the Pan-Homo branch c. 10 million years ago. But this is based on a most unlikely assumption of Pan-Homo divergence happening only 6 million years ago, when it's surely of at least 8 million years (and maybe as many as 10 million). A corrected estimate for the Gorilla branch could then be between 13 to 18 million years in fact.
