How Much Is That in Dog Years? The Advent of Canine Population Genomics

ABSTRACT authors comment on two studies that analyzed multiple genomes of dogs and wolves. The studies reached different conclusions about the date and population effects, a disparity attributed to reliance on molecular evolutionary rates that differ by an order of magnitude. The results of the first study are said to indicate a more complex pattern of amylase copy number variation in dogs and wolves reflecting humans' relationship with dogs, but may not have resulted during early domestication
