Ideas For Problems

Raw ideas for problems that no one has developed yet. Like an idea? Flesh it out, then post it back for review and publication.

Amylase expansion
Wolves have 2 copies of the amylase gene, while domesticated dogs (and humans) have 5 to 30+ copies.

Some American dog breeds really ARE native!
A study published July 2013 compared mitoDNA of Inuit, Eskimo and Greenland dogs, Alaskan Malamute, Chihuahua, xoloitzcuintli and perro sín pelo del Peru to both East Asian & European dogs. Data for malamutes were ambiguous, but they found NO mitoDNA signatures from European dogs in Inuit, Eskimo and Greenland dogs, and only 30% European markers in chihuahuas, xoloitzcuintlis and perro sín pelo del Peru. They also described the first DNA evidence showing the Carolina dogs (a pariah breed) may have ancient Asian roots. Their data strengthen the hypothesis that dogs present in pre-Columbian America arrived along with humans from Asia via the Bering bridge.
