It's National Dog Day today so on the subject of dog domestication and their ancient DNA, here is a re-post of the special Science did earlier this year:
http://www.sciencemag.org/site/extra/dogs/
Special CollectionDogs: Scientist's Best Friend. map. Collage by Chrystal Smith/Science. What does it mean when a dog wags its tail? How are dogs helping us fight diseases? And how did dogs evolve from wolves? Check out the Science's latest coverage of man's best friend to find out.

Researchers have analyzed variations in the DNA of hundreds of people living around the planet to see how selection affects the human genome. "The take-home message is that we continue to find a lot more genetic variation between humans than we appreciated previously," University of Washington’s Evan Eichler tells The Scientist.

So climate had more of an effect driving some species to extinction then!
http://www.sciencemag.org/content/349/6248/602.abstract
Climate killed off the megafauna The causes of the Pleistocene extinctions of large numbers of megafaunal species in the Northern Hemisphere remain unclear. A range of evidence points to human hunting, climate change, or a combination of both. Using ancient DNA and detailed paleoclimate data, Cooper et al. report a close relationship between Pleistocene megafaunal extinction events and rapid warming events at the start of interstadial periods.

IFL does it's own version from the Nature paper posted here yesterday:
http://www.iflscience.com/plants-and-animals/how-neanderthals-made-their-mark-our-species
Ancient members of our species had sex with Neanderthals. That lineage contributes to 1–3% of the DNA in almost everyone outside of sub-Saharan Africa today. This much we know. When, where, and how often is a bit more murky.

This maybe of some use here for interested in Neanderthal Genetics:
http://www.gibmuseum.gi/Calpe_Home.html
Calpe 2015. Redefining the Neanderthals. The year, when we are celebrating our 85th anniversary, the Gibraltar Museum has put together a very special and high-profile programme of international speakers who will converge on Gibraltar to discuss the topic of “Redefining the Neanderthals”.

Hot off the press! This is covered in both Nature and Science, see this article to be linked to them:
http://www.bbc.co.uk/news/science-environment-33612869
Two separate genetic analyses have found evidence for a surprising genetic link between the native populations of the Americas and Oceania.
