Ancestors of 20th century humanity may be diverging from other hominid variations now...specifically, European and Asian groups may represent the most advanced strains of humanity worldwide, rather than any African line. Some theories see virtually all substantial human evolution taking place primarily in Africa, with one or more waves of migrations outwards to Eurasia spreading the genetic improvements worldwide. The latest genetic finds seem to dispute this, saying that after a certain point human evolution was occuring faster in Eurasia than Africa, and perhaps feeding evolutionary improvements back to the hominid homelands instead, via migration and competition.

If it is true that Eurasians began outpacing African hominids during this time, it may have had something to do with the several extra geophysical advantages (and challenges) the Eurasian continent itself offered natives compared to Africa, as described for later developments regarding humanity by Jared Diamond in articles like "Why Did Human History Unfold Differently On Different Continents For The Last 13,000 Years? -- A Talk By Jared Diamond", The Third Culture, found on or about 1-2-99 on the web |
