Sort of fits into Glenn's scenarios, I think.

Boston, Mass. -- Some unique behaviors associated with modern
humans--including a shift in diet and the earliest evidence of personal
ornaments like beads--may be linked to an increase in human population

a
new species in Africa around 200,000 years ago, subsequently migrating
