Evolution of the Dog Family
It seems that dogs have been man’s best friend since the beginning of time, but in reality, it isn’t true. While the lives of canines and humanity have been interlaced for quite a while, it didn’t happen overnight. It took a lot of work to domesticate dogs into partners and pets. It’s believed that they started out as wolves in the wild and there wasn’t always the current number of breeds in the world.
The Evolution of the Domestic Dog
It’s known that dogs have been domesticated for quite a while, but it’s not all that clear how it originally happened way back in the beginning. The oldest known fossil belonging to a domesticated dog dates back to around 14,000 years ago. However, there is no actual fossil link between ancient wolves and the smaller dogs that were discovered from the same time period, lending some questions to whether these smaller dogs were domesticated wolves or a separate but related breed of animal. In fact, the origin of dogs (not wolves) has been quite a mystery. There are theories that man took wolf cubs from wolves and domesticated them anywhere from 10,000 years ago to 140,00 years ago but the exact time frame is still unconfirmed.

Evolution of Wild Dogs
Wolves are believed to have evolved from small primitive carnivores known as miacids. These animals existed 50 million years ago. Wild dogs or wolves most likely originated in Asia, around 700,000 years ago. Fossils have been found to support this theory. The dire wolf, the largest type of wolf, was believed to have evolved in North America at an even earlier date. The dire and grey wolves shared a continent until most large creatures – dire wolves included – went extinct around 16,000 years ago. Scientists believe that wild dogs came from these wolves, before they became domesticated dogs.

Interspecific hybridization is the breeding process that takes place between different species. For instance, scientists believe that red wolves are the product of natural interspecific hybridization between grey wolves and coyotes. Many of today’s dog breeds are the result of this type of breeding. Pure breeds from different dog breeds are bred together and the puppies born are considered hybrids with traits from both of their parents. The phrase “designer dog” is often used in reference to breeding that is done in this manner.
