Re: When did human races split?

Does anyone know the up to date estimates on when the major races of
human-kind split apart? For example if you go back far enough we must
have all been African. When did the poulations split into negroids,
caucasoids, South East Asians/pacific islanders and North East Asians?

Here's what I found on wikipedia:

" According to The Human Species (2003) and Physical Anthropology,
humanity can be divided into two major braches: the African branch and
the non-African branch. The non-African branch includes two subgroups,
one Eurasian and the other Oceanic. The Eurasian and Oceanic branches
are the products of this common origin. The Eurasian branch split into
the Caucasoid and Mongoloid branches. The Mongoloid branch then divided
into the East Asian subgroup and the Amerindian subgroup. The Oceanic
branch divided into the Southeast Asian subgroup and the Pacific
Islander subgroup. According to The Human Species (2003), East Asians
generally are more genetically similar to the South Asians than to
Southeast Asians, because the Far East and the Indian Subcontinent are
members of the Eurasian branch while Southeast Asians (including
southern Chinese) are members or the Oceanic branch"

Now I'm wondering if this information is still generally accepted by
experts, and I'm wondering when each of these splits occured. When did
Africans split from non-Africans? I've heard everything from 50,000 to
150,000 years ago. When did the Eurasian branch split into mongoloids
and caucasoids?
