“We came to the conclusion that our data consisting of prehistoric three Neolithic genomes and DNA from thousands of modern dogs from across the world supported only a single domestication event from a group of wolves somewhere in Eurasia sometime between 20,000 to 40,000 years ago,” co-author Krishna Veeramah, an assistant professor of ecology and evolution at Stony Brook University, told Gizmodo. “In addition, most of the dogs people keep as pets today are likely genetically the descendants of the dogs that lived amongst the first European farmers 7,000 years ago, and perhaps even as far back as 14,000 years ago when people were still practicing a hunter-gatherer lifestyle.”
Disagreement on the issue of climate change was anticipated from the beginning of the meeting in Hamburg and Germany Chancellor Angela Merkel has expressed that is “the one crucial issue” to be discussed at the meeting. The US broke with the other members of G20 in June when it abandoned a coalition of 147 nations in the Paris Climate Accord. At the time, Trump insisted that the agreement would be renegotiated but other leaders said that was a pipe dream. Chancellor Merkel reiterated in Hamburg that “the other 19 member states of the G20 say that the Paris agreement is irreversible.” She also made it clear that she “deplores” the fact that the US pulled out of the accord.
