According to my courses, Homo sapiens appeared around 300,000 yrs. ago,
(so-called 'archaic' sapiens) and modern man, H.sapiens sapiens appeared
approximately 120,000-100,000 yrs. ago.
According to DNA hybridization studies, and assuming a uniform molecular
clock, the pongid-hominid split occured approximately 7-5mya.
