Pat Shipman's argument that Wolf-Dogs enabled humans to outcompete neanderthals

The scientists determined genetic diversity was just as high for the African dogs as it was for the East Asian village dogs that were the focus of the earlier research.
"Species tend to show the highest genetic diversity near their place of origin," said Boyko. He explained that this is because the species have "been there longer and therefore have had more time to accumulate diversity, and because as a species expands its range by colonizing a new region, it usually does so with a relatively small band of individuals carrying just a subset of the genetic diversity found in the ancestral population."

Here, by comparing population genetic results of humans and dogs from Siberia, Beringia, and North America, we show that there is a close correlation in the movement and divergences of their respective lineages. This evidence places constraints on when and where dog domestication took place. Most significantly, it suggests that dogs were domesticated in Siberia by ∼23,000 y ago, possibly while both people and wolves were isolated during the harsh climate of the Last Glacial Maximum. Dogs then accompanied the first people into the Americas and traveled with them as humans rapidly dispersed into the continent beginning ∼15,000 y ago.

23,000 years ago was the last common ancestor of two domestic dogs in Siberia....Sledding was probably the first use of dogs - not hunting - at least in Siberia....

that Chow Chows originated from the Chinese indigenous dog about 8300 years ago.
