Keeping Warm -- Evolution to the Rescue
Today's timely site from the folks at the Why Files takes a look at the
latest scientific findings on how humans adapted physiologically to living
in a polar climate. Gentle Subscribers shivering in much of North America
recently may enjoy taking the lofty view of the body's evolution to life in
a cold climate presented at this web page.
"How did people get accustomed to living near the poles? ... Making body
heat is a big problem. For most of human history, staying warm was not just
a matter of comfort, but of survival. ... Understanding the when, where and
how of this adaptation is a critical issue for studying human migration,
and now comes an answer, [from] Douglas Wallace, a population geneticist at
the University of California at Irvine." - from the website
The site features an upbeat and lucid examination of groundbreaking
research in the human evolutionary response to living in a polar climate.
The relationship of DNA sequences of mitochondria and adenosine
triphosphate (ATP) production is explained in layperson's terms with the
aid of a large, friendly diagram. Additional information reveals some
surprising implications of the mitochondria DNA adaptation.
Nip over to the site for a fascinating explanation of the body's adaptation
