Why do domestic animals look different from wild animals?

This statement is more general, and not all domestic animals are necessarily very different from wild animals. It's just that some domestic animals are pets, so they will look more beautiful and richer than wild animals. For example, dogs are an example. Often wild dogs or wolves are single in appearance, all of which are one color and figure, but pet dogs have all kinds of appearances, whether curly or mini. Wild animals living in nature, if they are of the same species, have a uniform internal appearance, almost all of which are the same appearance, while wild boar or bison, because they often fight with carnivores, look more fierce and stronger than domestic pigs and domestic cattle, and their bodies are more robust, rather than simply long meat.

I believe we all know that many poultry and livestock raised around us are domesticated by wild animals. After all, human beings are very powerful and have tamed many animals. For example, wolves have become dogs after human domestication. However, many netizens have found a common phenomenon, that is, wild animals and domestic animals always look different, even if their blood relationship is close, and sometimes they can tell the appearance of wild animals and domestic animals at a glance. This reason is the same as that of wild animals.

Let's talk about the difference between dogs and wolves. Both wolves and wild dogs have the same appearance. For example, the hair color is mainly grayish yellow, but there are many types of domestic pet dogs. For example, pugs, Teddy and huskies have different looks. This is because of artificial modification. Because these are ornamental animals, many dogs' looks change according to human preferences, but wild animals are often thousands.

Let's talk about the differences in looks caused by living habits. Compared with domestic pigs and cattle, wild boar and bison are obviously more fierce and robust. Perhaps domestic animals are not smaller than them, or even bigger. However, domestic animals often grow fat meat instead of exercising in the wild, while wild boar and bison look much bigger and have stronger meat, because they live in the wild and face different situations every day.
