Ancient Life Could Return to Arctic and More

Ancient Life Could Return to Arctic and More

There’s been a lot of cool news in natural science lately, so today I thought I’d provide some synopses and links. Enjoy!

Ancient Life Could Return to Arctic by 2010:

  • Global warming means that the ancient forests of northern Canada could return as early as 2100.
  • Fossilized forests of willow, pine, spruce, oak, and hickory, which grew in Nunavut’s Bylot Island  between 2.6 and 3 million years ago, may find conditions warm enough to begin growth several decades from now.
  • Of course, it takes hundreds of years for a forest to develop.

Khoe-San Peoples Diverged Before ‘Out-of-Africa’ Migration of Modern Humans:

Genetic Mutation May Have Spurred Human Migration

  • And speaking of early human migration, new Wake Forest Baptist Medical Research Center has found that a genetic mutation that occurred 85,000 years ago may have allowed more immigration for modern humans.
  • The mutation allowed humans to convert plant-based polyunsaturated fats (PUFA) to PUFAs for the brain, which increase brain size and develop its complexity.
  • Although modern humans developed 180,000 years ago, they mostly stayed in Africa until about 100,000 years ago.
