In Dog DNA, Small Size Has an Ancient Pedigree
The New York Times
New research finds a mutation that suggests the more diminutive canines’ DNA dates back to ancient wolves.
Big dogs get all the glory. I don’t have a peer-reviewed paper to prove it, but I can quote the greatest country singer of all time, Hank Williams, who is certainly some kind of authority.
To wit: “Move over little dog cause the big dog’s movin’ in.”
Not so fast, big dogs. A group of researchers who may not sing as well as Hank, but who make some impressive DNA charts, reported Thursday that part of the dog DNA responsible for small size is likely older than a variation that contributes to large size. The small-size version seems to be ancestral.
