On some matters \u2014 such as the types of genetic changes that make the two differ \u2014 the researchers are more or less in agreement. Yet the teams have all arrived at wildly different conclusions about the timing, location and basis for the reinvention of ferocious wolves as placid pooches. \u201cIt\u2019s a sexy field,\u201d says Greger Larson, an archaeogeneticist at the University of Durham, UK. He has won a \u00a3950,000 (US$1.5-million) grant to study dog domestication starting in October. \u201cYou\u2019ve got a lot of big personalities, a lot of money, and people who want to get their\u00a0<i>Nature<\/i>\u00a0paper first.\u201d<\/p>\n<p>In January, Erik Axelsson and Kerstin Lindblad-Toh, geneticists at Uppsala University in Sweden, and their colleagues reported in<i>Nature<\/i><sup><a id=\"ref-link-1\" title=\"Axelsson, E. et al.

In the paper and in media interviews, the researchers argued that dog domestication was catalysed by the dawn of agriculture around 10,000\u00a0years ago in the Middle East, as wolves began to loiter around human settlements and rubbish heaps (see\u00a0<a href=\"http:\/\/doi.org\/mv4\" target=\"_blank\"><i>Nature<\/i>http:\/\/doi.org\/mv4; 2013<\/a>).<\/p>\n<p>But Larson, who has worked with Lindblad-Toh on other projects, says that their claim is dubious. He notes that bones that look similar to those of domestic dogs predate the Neolithic revolution by at least several thousand years, so domestication must have occurred before then.<\/p>\n<p>[ <a href=\"http:\/\/www.nature.com\/news\/dog-genetics-spur-scientific-spat-1.13227\" target=\"_blank\">click to continue reading at NATURE.com<\/a> ]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>from NATURE Dog genetics spur scientific spat Researchers disagree over canine domestication. by\u00a0Ewen Callaway Scientists investigating the transformation of wolves into dogs are behaving a bit like the animals they study, as disputes roil among those using genetics to understand dog domestication.
