Um.  I don't think this is correct.  In the "Eve" episode of Nova last
year, the diagram was resolved by molecular similarity studies in the
opposite way (that is, "chimps" and "gorillas" should be exchanged in
the above diagram).

If *I'm* remembering the program correctly, the human-chimp common
ancestor existed about 5 million years ago, and the human-chimp-gorilla
common ancestor existed about 8-12 million years ago.

Molecularly, gorillas are an equal distance from either humans or chimps
(about 95% similarity according to the Nova episode mentioned), while
chimps are closer to humans than to gorillas (about 98% similarity).
