Allergies May Come From Neanderthals

New studies published in the American Journal of Human Genetics have revealed evidence that human interbreeding with Neanderthals may have given us the genes responsible for allergies.

These same genes, it should be noted, likely played an important role as well in helping our species adapt to the new climate, flora and fauna, and pathogens of environments like Europe after our ancestors left Africa. Neanderthals inhabited these places for many thousands of years before our arrival, giving them a valuable head start which interbreeding may have passed on to us.

  1. Allergies are probably one price we pay for living in more or less 'germ free' environments. 
    Our immune systems like any military set up needs some 'exercises' or 'war practice' - if no target is easily available the immune system seems to pick one and the human body suffers 'allergy' as a result.
