In this New York Times article, it introduced 27 new genomes
of ancient dogs. This study brings a lot more findings as well. The study
suggests dogs were domesticates around 20,000 years ago. Another idea it suggests
in ancient dogs being more genetically diverse than modern dogs. This all
provides new information and new thoughts on dog domestication. They also talk
about dogs coming from an extinct form of wolves, and how fast dogs spread all
across the globe. This brings up a lot of interesting theories on these dogs.
Some scientists think humans have an effect on this, and humans and dogs migrated
together, but in some areas this in not true. I believe some dogs where
probably taken to travel with humans resulting in the migration. These specific
dog breeds were probably pasted on from generations resulting in only certain
populations of dogs migrating. I agree with most of the theories presented in
this article, like humans and dog migration interacting intentionally. I also believe the theory dogs came from an extinct
form of wolves. They have many similarities, but so many differences from the
current wolves that dogs could be from an extinct version of wolves.
This is a very interesting article, I enjoy the theories presented on how humans and dogs had migrated together, it paints a nice picture but also raises questions on what would our day to day lives be if this were not to happen. Would we still have domesticated these wonderful animals? I also love to think of the fact that dogs descend from wolves, even the smallest of dogs.
