Mummy lice found in Peru may give new clues about human migration

Lice from 1,000-year-old mummies in Peru may unravel important clues about a different sort of passage: the migration patterns of Americas earliest humans, a new University of Florida study suggests.

...scientists may be able to link the 1,000-year-old lice found in the Western Hemisphere with those in Siberia or Mongolia, confirming existing theories that Americas earliest residents originated there, he said.
Had these immigrants traveled by land masses, there was a very small window of time, about 13,000 years ago, when the glaciers retreated enough to allow passage through the Bering Strait on the way to South America, Reed said. Another proposed theory is a seafaring route, but this would have required sophisticated oceangoing vessels for which no evidence from the time exists, he said.

The idea that human beings didn’t have seaworthy boats 13,500 years ago has pretty much been abandoned. It’s pretty obvious such boats existed and were in use, possibly since 50,000 years ago when Australia was first settled.
