Basically yes. But the genesis seems to be placed slightly more than 6000 years ago although the motivation is the same. Dates anywhere between 40,000 to 200,00 years are proposed for a sudden evolution of modern humans. We know that species form genetic gradients through both time and space and when we compare opposite ends of either extreme we see the greatest difference. There is usually no really sudden huge leap in either gradient although geographic features and elements of punctuated equilibrium lead to reasonably abrupt changes. Make sense?

Regarding bonobo/ chimp separation, about 2 million years I think is generally accepted. Couldn't find anything definite with a quick search.
