Science Daily: Lice DNA Study Shows Humans First Wore Clothes 170,000 Years Ago.
ScienceDaily (Jan. 7, 2011) — A new University of Florida study following the evolution of lice shows modern humans started wearing clothes about 170,000 years ago. ...Hmmm...the data shows that even Neanderthals wore clothes prior to 168,000 B.C. I guess modern humans devolved to be too stupid to figure that out.
The data shows modern humans started wearing clothes about 70,000 years before migrating into colder climates and higher latitudes, which began about 100,000 years ago. This date would be virtually impossible to determine using archaeological data because early clothing would not survive in archaeological sites.
