Why Are There Different Breeds in Animals, But Why Don’t We As Humans?

As humans, just like the diversity we see in animals We don’t have different breeds. Yes, there are races, but we cannot call them breeds.

To understand why we do not have breeds like animals, Our living conditions differ from other animals, starting from the first humans We need to delve into its interesting depths.

First, it would be useful to go back in time a little.

Early hominids (great apes), ca. It evolved from monkeys 5 million years ago. Homo sapiens did not emerge until 150,000-200,000 years ago in East Africa, where we spent most of our evolution as a species.

Our species first left Africa approximately 50,000-100,000 years ago and rapidly spread throughout the world. That’s all we are descendants of our last African ancestors we are coming. Unlike most animals, relatively we are a young species And we are extremely active. Therefore, it is unlikely that we will be divided into other genera because the most important factors for dividing into subspecies are; isolation and time.

Many other animal species have existed much longer.

Other animals had much more opportunity to accumulate genetic variants. Penguins, for example, have twice as much genetic diversity as humans! Even our closest living relative, the chimpanzee, has been around for at least a few million years, and in a group of chimpanzees in Gomba, more than the entire human species There is genetic diversity.

The reason why domesticated animals such as dogs have so many breeds is that they can be grown under laboratory conditions. by artificial means We produce new breeds. We as humans, on the other hand, are widely intermixed. To put it more clearly; Many of us have many different genetic variations in our background, whether Icelandic or Kurdish. It’s kind of like a breed, actually.

As humans, we are not limited to a single geography.

Animals; limited by geographical features such as rivers, mountains, and glaciers. Therefore, it is much easier for them to isolate. On the other hand, people easily adapt to the environment and They are not limited to a single geography. We migrate, there are wars, there is trade… Therefore, we cannot have a long time with limited space for genetic diversity to increase and we cannot develop breeds.
