00:03dogs are now man's best friend but at some point likely over 23,000 years ago
00:08dogs were still wolves not yet domesticated but now experts are
00:12looking into what makes some dogs act more like wolves specifically what
00:15drives some breeds to do this more than others the researchers looked at 28
00:23purebred breeds playing for them recordings of wolves howling finding
00:27that while there wasn't any statistical difference in how young dogs
00:29reacted with older dogs there was here's one of the researchers to explain
00:33the main finding was that the breed matters actually more precisely that those breeds
00:44which are genetically closer to wolves are more prone to responded howling and they
00:51also show more stress signals than dogs which are less related to wolves the
00:56stress signals being yawning shaking the body licking the mouth and scratching
01:00all were more frequent in dogs with closer genetic ties to wolves so what do
01:07these findings mean exactly well the researchers say that selective dog
01:10breeding has brought dogs closer to human society than to their historical wolf
