Domestication Might've Been Bad For Horses
A group of scientists looked at the genetics behind the domestication of the horse and showed how human manipulation changed horses' DNA.By Sebastian Martinez | December 16, 2014
Scientists tracing the horse's genome have found as humans domesticated the wild horse thousands of years ago, they affected the horse's DNA.
Scientists looked at two samples from the Taymyr Peninsula in Siberia, one of which dates back some 16,000 years and the other more than 40,000 years — well before humans domesticated horses. (Video via National Geographic)
In their research, two groups of genes covering social behavior, learning capabilities and muscular development, among other traits, could've been key in the domestication process.
