Washington D.C. [USA] June 28: It is worth noting that dogs are the best friend of man and the faithful companions on which a human can rely.
They live with us, play with us and sleep with us. But how did a wolf-like animal evolve for tens of thousands of years to become a beloved member of a family?
Through genomics, scientists at the University of Michigan have compared the DNA of a dog and a wolf. the genes involved in domestication.
Research has identified that in some places DNAs do not seem to match.
Researchers used statistical methods to unravel the genetic changes of old dogs and wolves, found at landfills. 5000 years ago. It results from the first efforts of domestication of the man from those badociated with the development of specific races.
"The hypothesis of the neural crest postulates that the phenotypes we see in domesticated animals come back again and again." Coloring, tame behavior – can be explained by genetic changes that act in a certain type cells during development called neural crest cells, which are incredibly important and contribute to all kinds of adult tissue, "says postdoctoral researcher Amanda Pendleton.
