Do I have this roughly right? About our last common ancestor

[IgnorantApe]

1. So, roughly 7 million years ago there was a population of African apes.
2. This population split up (for whatever reason)
3. The various new sub-populations then evolved into separate creatures: humans, chimps, gorillas

The human-chimp last common ancestor was the last ape who gave birth to the creatures who would end up splitting up geographically and passing on their DNA in separate places eventually culminating in the evolution of the chimpanzees (pan & bonobo) and modern humans.

Is that essentially correct?
