Where did your dog come from? New tree of breeds may hold the answer

From the 80-kilogram Great Dane to the 1-kilogram tiny teacup poodle, there seems to be a dog for everyone. Now, the largest genetic analysis to date has figured out how those breeds came to be, which ones are really closely related, and what makes some dogs more susceptible to certain diseases.
"They show that by using genetics, you can really show what was going on as [breeders] were making these breeds," says Elinor Karlsson, a computational biologist at the University of Massachusetts Medical Center in Worcester who was not involved with the work.
After dogs were initially domesticated—likely between 15,000 and 30,000 years ago—people picked the best hunters, house guards, and herding animals to be their best friends, depending on their needs. There were dogs for war and for cuddling, for fur and meat, and for being good companions. Today dogs come in 350 or so breeds, each with specific traits and behaviors. Many arose in the past 200 years. Some studies have defined the genetics of a relatively small number of breeds, but none has*been comprehensive enough to show how and when most came into existence. "The whole period in between [domestication and today] has been a black box," Karlsson says.

Ha, thanks for posting, that is pretty cool.
Ah never mind!
Dog sex doesn't HAVE to include manual stimulation by a human every single time.
Relax, you'll get yours soon enough.
Ostrander and Parker say they see this publication as a midpoint, not an endpoint.
"We had reached a point where we could begin to do some of the things we wanted to do," Ostrander explains. "By no means are we done."
