why the fur developed to animals why not for humans
Answers
Answer:
We know that at one point humans did have fur! But we don’t know why we lost it, so we have to guess.
Scientists think that our ancestors (so think of your grandmother’s grandmother’s grandmother’s grandmother but over a million years ago) experienced a very big change in the climate. The world became much hotter, and that meant that people had to start travelling further and further to find food.
Dr Nina Jablonski, an expert on ancient humans, thinks that slightly less hairy people may have been in better shape to travel these distances because they would have been able to keep cool more easily.
So if you’re less hairy, it means you can travel a long way, which means you can eat more food. If you’re more hairy, it means you can only travel a short way before you get too hot, which means you find less food and go hungry.
That means the people with less hair were the ones who stayed alive long enough to have kids. And just like how you might have the same eye or hair colour as one of your parents, those kids also inherited having less hair from their parents. That’s why nowadays you won’t see very furry humans.
All mammals (warm-blooded animals) have body hair, which protects their skin from sunlight and means it won’t get cut or grazed as much, but every animal has different kinds of hair for different reasons, such as:
The colour of hair can be very useful for animals like kangaroos and dingos because it can make the animal difficult to see. That makes it easier to hide from predators, and also easier for predators to stalk prey.Most animals need hair for sun protection, but some animals, like naked mole rats which always live underground, have no fur because they don’t need any protection from the sun.
Whales and dolphins, mammals that live in the sea, have almost no hair because it is very difficult to swim if you are covered in fur.
Hair can help keep you very warm, which is helpful in a cold place. Sea otters have some of the warmest fur in the world because they live in freezing cold water next to the Arctic.
If you are a very small animal like a mouse you can get cold easily, so hair is very important. But if you are a big animal like an elephant you might not need the warmth of hair as much.
