I wonder, how many new genes are present in dog's bread in captivity which are completely absent from wolves in the wild. I'm curious of our breeding has led to mostly/entirely phenomenological genetic changes or if there has been genetic mutations as well, which might suggest a path of speciation is occuring.

@freemo I can't answer your question precisely, but I do remember reading that black colored fur does not occur in the wild phenotype, and that any wolves that have black fur is because somewhere in their ancestry was a mating with a domestic dog.
