Ancient Dog Skull Shows Early Pet Domestication

Eddie W. -- In the 1970’s, wolf fossils were found in the Atlay Mountains of Sibera, and it was recently looked up and was found out that it was one of the first pets. Usually, 14,000 year old dog fossils are the oldest ones scientists find but this one was older, close to 26,500 years old. Because there’s not a lot of history recorded about wolves, scientists don’t know how the genes of the wolves’ population changed to be dogs and when it actually happened. ’’ That's why our find is very important—we have a very lucky case,” ( Yaroslav Kuzmin). This quote shows that they needed to find out about that dog in order to get some info on when wolves’ genes population changed. Yaroslav Kuzmin and a group of scientists compared the fossils of the dog to other wolves’ bones and dog fossils about the same age as the other dog. They found out that the dog was similar to dogs in Greenland because it looked similar to one. ’’Animals that were more comfortable around humans underwent changes in their growth rates—probably regulated by hormones—that eventually changed their reproductive patterns, sizes, and shapes, turning them into dogs,’’ ( Susan Crawford). This quote is evidence that the wolf could have enjoyed being around people so much, that there hormones took control of how they looked and their inherited traits changed.


I think this is really interesting because this one of the first pets that people had. It is helpful to people because it involves some history of wolves and dogs. The Article used evidence from scientists and zooarchaeologists, and anthoropologists so I think this author, you could agree with. This article includes a photo that would call attention to readers. This article has a few historic details about fossils. It explains why and how things could have happened. When there was evidence the article said where it came from.
