One in 3.1 billion

Interesting article on a Penn State finding a mutation on a letter that caused skin to whiten in those who thrived in Europe. My family already calls me a mutant because of my red hair. Apparently there are 3.1 billion letters. The gene in question is SLC24A5.

Another good article: http://www.courant.com/news/health/hc-gene1216.artdec16,0,604779.story?coll=hc-headlines-health

"Because modern humans originated in Africa, genetic variation among people of African descent tend to be the greatest of all ethnic groups." ... very interesting.
