Did overhunting lead to domestication? : Past Horizons Archaeology

Did overhunting lead to domestication? : Past Horizons Archaeology | Animal Domesication | Scoop.it

A new study on the populations of wild cattle and boars in the Levant Valley by Nimrod Marom, Guy Bar-OzLaboratory of Archaeozoology, University of Haifa, Israel has been published in PLOSone online Journal. The research helps reshape our present understanding on the beginning of agriculture and domestication of animals.

Dog and man: a 30,000 year friendship : Gene Expression

Dog and man: a 30,000 year friendship : Gene Expression | Animal Domesication | Scoop.it

To the left is a figure which illustrates the phylogenetic inferences from a new paper in Nature Communications, The genomics of selection in dogs and the parallel evolution between dogs and humans (see Carl Zimmer’s coverage in The New York Times). Why is this paper important? The first thing that jumped out at me is that because they’re using whole genomes (~10X coverage) of a selection of dogs and wolves the results aren’t as subject to the bias of using “chips” of polymorphisms discovered in dogs on wolves (see: Genome-wide SNP and haplotype analyses reveal a rich history underlying dog domestication). The second aspect is that the coalescence of the dog vs. wolf lineage is pushed further back in time than earlier genetic work, by a factor of three. A standard model for the origin of dogs is that they arose in the Middle East ~10,000-15,000 years ago , possibly as part of the broad shift of lifestyles which culminated in the Neolithic Revolution.
