Now, a study published Friday in the journal Science has shown that the genetic diversity in modern dogs can be traced back to the end of the last Ice Age, linking Fido and Rex to ancient canine populations.
Researchers studied DNA extracted from bones from ancient dogs for clues to evolutionary changes that occurred thousands of years ago, and found that just after the Ice Age, there were at least five types of dog with distinct genetic ancestries. They found that dog lineages have "mixed and combined," and are still present in the dogs of today.
...
And while modern European dogs appear to come in such different shapes and sizes, genetically, they share a recent common ancestor and are not as genetically diverse as they once were.
Bergstrom told CNN that before 4,000-5,000 years ago, Europe had a greater diversity of dogs, with some animals similar to Middle Eastern, Siberian and "everything in-between" dogs.
At some stage, however, this diversity was lost, and is not found in today's European dogs.
"If we look at present-day (European) dogs, despite their enormous variation in terms of what they look like they actually derive from just a small subset of the diversity that used to exist in Europe," he said.
"It's a bit of a mystery how this happened," Bergstrom told CNN, "but likely at some point a single population of dogs banded across Europe and replaced everyone else."

Which brings us to the question how come advanced life forms have a face?
My Podengo, Murph is not mentioned ! C’mon CNN
Traced to 600 BC the Podengo has been kept wild and pure by the Portugese for the last 1500 years.
We call Murph the “cave dog” for his savage hunting skills, unbelievable hardiness, gnarly fur, curved teeth and at first his lack of wanting to be civilized.
Never seen anything kill rabbits so effectively. They don’t get away. He grabs them by the back, snaps their back then immediately swallows them hole, head first, legs down.
He now knows how to pretend at manners thanks to 7 years with his adopted Boston Terrier brother.
Wish he hadn’t been spayed ... a rescue runaway.
Genesis Chapter 1. Created and reproduce after their KIND.
Variation based on already inherent genetics, nothing new under the sun.
Mix dogs of all sorts over a few generations and you get a Dog Dog. It will have the ability to produce and make more......Dogs; then selectively breed for traits and you’ll get big dogs, little dogs, shorthairs, long hairs, droopy ears, tall ears.....all with long tails....But that ain’t evolution.

My dog Rayol is a default dog. Mixed breed, 30 lbs. looks like a coyote with a curly tail.
Compare that to post #5.
A dog’s butt.
Neanderthal women were referred to as “dogs” by Cro-Magnon men. There were 5 types: Ugly, Really Ugly, Ultimate Ugly,
Beyond Ugly, and Socially Distanced Ugly.
Did Cro-Magnon men have beer goggles?
“It’s a bit of a mystery how this happened,”
sometimes looks are everything?
didn’t they have coyotes back then?
sorry i dont believe anything from cnn
My eyes! My eyes!
These are Indian dogs, no?
