A new study of the dog family tree could rock the world of breeding. It could do so by proving that certain breeds actually descended from very different genetic lines. Even in cases when they were grouped together.
Dog Family Tree Shows More Diversity Than Believed
“In retrospect, that makes sense. What qualities you’d want in a dog that herds bison are different from mountain goats, which are different from sheep, and so on.”
This is according to the study author, Elaine Ostrander from the National Institutes of Health. This research has helped straighten out some of those genetic lines.Another piece of information discovered in this research on the dog family tree showed that there was once a uniquely American breed of dog. This possibly arrived with the first nomadic hunters. These animals were separated for thousands of years from their European and Asian kin. Later, as settlers came from Europe, they brought their breeds with them. As they did so, the American species is believed to have gradually died out.
No genetic trace of this unique American dog has ever been detected, until now. Two breeds, the Peruvian hairless dog, and the Xoloitzcuintli, clustered together in the data examined by the research. This suggested to the team that those two breeds might have the last genetic leftovers of this earlier, native dog.
