What are some mammals with very short hair?

Most of the 5,400 mammal species are covered with enough hair that they are strong enough to be called "fur" - both warning and placentals are usually covered with a striking layer of fur, helping them maintain warm. Obvious examples are kangaroos, mice, bears, cats and dogs.

Some mammals have hair so short that if you look at them from a distance, it's not obvious. Only when you look close to them, is it clear that they are only mammals with very short hair. Examples of mammals with very short hair include elephants, rhinos, cetaceans (whales and relatives), naked molish rat and we humans. Especially people who are among mammals with very short hair did not cause any small amount of controversy, and some creationists claimed that the human absence of long hair is proof that we have been created as a fundamentally different entity than the rest of the animal kingdom.

Even evolutionary biologists.Rt that virtually disappears, is unclear and the object is a lot of controversy.For sea mammals such as whales, the reason seems to be clearer - it will be streamlined for swimming. Naked molish rat is one of the mammals with very short hair due to its underground lifestyle. Although the naked mole rat has several long hairs for sensory purposes, most of her skin is relatively free from him, giving him the name "naked".

Of course, the most controversial of mammals with very short hair are people. Why did people lose most of their hair a million years ago or something? Nobody knows it at the moment. Some scientists believe that the early members of the family homo , from which people have developed, spent so much time in the water that they have developed different adaptations for semi-desktop lifestyle, including short hair and increased subcutaneous fat. Others believe it has something to do. Overall, more research and theorization are needed.
