The DNA hybridization method, which has been nicely calibrated against
the fossil birds, gives the gorilla branch at 10-11 Myr, the chimp-
hominid split between 7.7 and 6.3 Myr.  This method is the most accurate
so far because it utilizes all the nuclear DNA, not just what is expressed
(and is thus under various rates of natural selection).  The 90+ percent
junk DNA isn't under selection and so probably has a constant clock rate
compared to proteins.
