In college, I remember hearing that someone had calculated that all humans living today were descended from everyone who lived before 1200 A.D.

That statistician (Joseph Chang) is referenced an article I recently read that points out some flaws in his ideas and mentions that currently statisticians guess that humanity’s most recent common ancestor lived during the Golden Age of Greece (and probably lived in Asia).

The article’s interesting in that it describes the logic and methodology the study followed (to a limited extent) and describes some of the obvious consequences (today’s Klansmen are undoubtedly descended from Africans).
