Siberian fossil revealed to be one of the oldest known domestic dogs March 6, Analysis of DNA extracted from a fossil tooth recovered in southern Siberia confirms that the tooth belonged to one of the oldest known ancestors of the modern dog, and is described in research published March 6 in the open
That close relationship that has existed since before they helped early humans take down mammoths. But the exactly how long canines have provided companionship just got a revision: The animal lived 35, years ago and was a type of ancient wolf, they determined.
That three-way split happened around the same time, and the Taimyr represents the most recent common ancestor of wolfs and dogs. Later, the Taimyr wolf lineage became extinct.
The researchers published their findings in Current Biology. If this model is correct then dogs were domesticated by hunter gatherers that led a fairly nomadic lifestyle. Larsen says that the archaeological evidence is biased towards the later stages of dog evolution because dogs probably didn't start looking like dogs as we know them until relatively recently.
However, he believes the process was a continuous one, so much so that he has banned the use of the words "dog" and "wolf" in his lab.
Further evidence of that muddling remains in modern day Siberian Huskies and Greenland sled dogs. They share a large number of genes with the extinct Taimyr wolves, because that ancient lineage apparently interbred with more domesticated dogs to give rise to those Arctic breeds.
The line between wolves and dogs was also blurred throughout the domestication process as animals from the wolf and dog lineages occasionally bred something they still do today. Still, despite this mixing with their wild cousins, dogs on the whole remain considerably more domesticated than cats.
But most people could have guessed that fact, even without science to back them up.Jan 19, · Imagine that some ancient wolves were slightly less timid around nomadic hunters and scavenged regularly from their kills and camps, and gradually evolved to .
The domestication of animals is the mutual relationship between animals and the humans who have influence on their care and reproduction. Charles Darwin recognized the small number of traits that made domesticated species different from their wild ancestors.
He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable.
Haplogroups A and B contained subclades that appeared to be the result of hybridization with wolves post-domestication, because each haplotype within each of these subclades was the result of a female wolf/male dog pairing. Wolf Origins.
The Evolutionary history of the wolf is not totaly clear, but many biologists believe that the wolf developed from primitive carnivores known as miacids. Smart News Keeping you current Humans May Have Domesticated Dogs Tens of Thousands of Years Earlier Than Thought Genetic analysis from an ancient wolf show just how.
When humans tamed wolves, dogs became the first domesticated animal. (Mary Altaffer/AP).
