Dogs: the first ate fish thanks to humans

We humans have really had a lot of influence on it diet of the first dogs exist on Earth. But when did wolves become dogs and why? The first specimens appeared 30,000 years ago and were domesticated by humans about 15,000 years ago. It is not known whether the merit belongs to mankind or to the invention of agriculture.

For example, an analysis was conducted between the physical characteristics and diet of 200 dogs and 200 wolves that lived in Siberia for the past 11 thousand years. It turns out that the first dogs changed their eating habits to get the company of humans. Siberia was chosen because the first dogs were domesticated there and then conquered the whole world. There are two theories about how wolves became dogs. The first is that thousands approached the human settlements and then came domesticated. The second is that some wolves developed the ability to absorb starch, which allowed the animals to get more food.

Further analysis of the remains of Siberian dogs and wolves revealed another, more complex theory. Early Siberian dogs were smaller than their wild relatives with a much more varied diet. Mainly sea ​​or lake food. Siberia has frozen waters and it is not easy to get food in such climatic conditions. Here wolves have certain physical characteristics that the first Siberian dogs did not have. Scholars therefore concluded that the animals then ate seafood or lake fruits, as they were obtained by humans. So dogs got used to hunting less and less and more and more “spoiled” by people.

Here, over time, the change in diet has also led them to new diseases and new parasites. In addition, resulting in the death of domestic dog populations. The survivors, on the other hand, stayed with a microbiome suitable for the human diet and confirms their status as pets.
