While fossil records prove that some anatomically
modern human groups reached the Levantine corridor (the
modern Middle East) as
early as 100,000 years ago, genetic testing indicates that
human populations inhabiting the globe today descended from a single group that
migrated from Africa only 70,000 years ago — an unexplained gap of 30,000 years.
This timeframe suggests that
early modern humans or Homo sapiens
migrated out of Africa thousands of years
earlier than what scientists previously thought.
