Dog Cages

Genetic analyses have so far yielded atypical results. Vilà, Savolainen, and colleagues (1997) concluded that the ancestors of dogs split off from other wolves between 75,000 and 135,000 years ago, while a postliminary analysis by Savolainen et al. (2002) indicated a "common origin from a one gene pool for all dog populations" between 40,000 and 15,000 years ago in East Asia.

Verginelli et al. (2005), however, suggest both sets of dates must be reevaluated in light of http://www.petsdo.com/store/dog/carriers-crates-cages recent findings showing that poorly calibrated molecular clocks have systematically overestimated the age of geologically recent events. On balance, and in arrangement with the archaeological evidence, 15,000 years ago is the most likely hour for the wolf-dog divergence.
