If humans were as varied as dogs we would range in height up to 22 feet tall and in weight more than 1,000 pounds! In the ultimate canine ancestral story, And Man Created Dog, traces the genetic journey from wolf to dog, taking you back 100,000 years to meet the "mother of all dogs."
It's no accident that dogs evolved this way, as humans we have been selectively breeding them for around 14,000 years to serve our needs as labourer, companion, hunter, herder and warrior, as well as to suit our aesthetic fancy.
They're not just your best friends, but likely your oldest.

Find out what scientists are learning about dogs' unique ability to communicate with humans, and how powerful brain chemicals work to cement our affection for each other. Delve into the history of selective breeding and see how man created dogs to serve our needs as laborers, companions, hunters, herders, and warriors, as well as to suit our aesthetic fancy.
From immense Great Danes and diminutive Chihuahuas to curly-haired poodles and streamlined greyhounds - it's no coincidence that dogs are in fact the most diverse mammals on the planet.
Recently, I had the chance to preview a National Geographic Channel special, And Man Created Dog (airing Sunday, August 8, 9p.m. ET/PT). This show is about canine evolution; one of our favorite topics! I must admit I had trouble with its title (too human-centric) and its diorama-like reenactments that confidently state scientific conjecture as proven fact. There is also too much of a “golly gee” flavor to the narrative for my taste. But mainly, I am disappointed that alternative theories of canine evolution aren’t presented, including one to which we subscribe: co-evolution. It’s possible that wolves shaped us as much as we shaped them. Considering that wolves have been among the leading megafauna predators for millions of years, our ancestors would have had a lot to learn by observing their hunting prowess.
Nonetheless, it is interesting and well worth watching. Two of our favorite researchers—UCLA’s Robert Wayne and Barnard’s Alexandra Horowitz—help explain the story, which includes an emphasis on the longevity of the canine/human partnership.
Another problem I have with the program is the lack of coverage about how closing breed registry books means that dog breeding (especially in the U.S.) has increased the prevalence of canine diseases and resultant health problems. This is such an important topic—it deserves more coverage (or a whole show unto its own). The program spends much too much time with more “exotic” storylines, such as how Italians train Newfies (and other water dogs) to perform water rescues. Or how Italians use dogs for their truffle hunting—seems as if some producer wanted to spend a paid vacation in Italy, perhaps.
Among the most poignant pieces of evidence for the long term association of “us” and dogs is an archeological finding from Chauvet Cave in Southern France: two sets of footprints—those of a dog (which are different than a wolf’s) and a young child—embedded close together in the fossilized mud of the cave floor. The propinquity of the two left no doubt that a prehistoric child and his dog were in that cave together 26,000 years ago! That is, in itself, worth tuning in for.
