First of all, most mammals have fur rather than hair.
Both fur and hair primarily provide warmth. Fur and hair, however, also provide distinctive markings that can be involved in mating, aid in touch-sense input, and provide protection from the sun.
In addition, some more aquatic mammals (such as seals and otters) have a high oil content in their coats, which aids in buoyancy in the water.
I'm almost certain that fur and hair have other uses, especially if you add whiskers into the larger hair-and-fur discussion.
mammals because mammals have hair and birds have feathers.
Answer:Having curly hair doesn't make you warmer than straight hair.FactWhat might keep you warmer is if you have more hair than other people. If you have more hair you have a better chance to keep your self warmer.
Many animals are born without fur. Among them are rats, mice, aardvarks, rabbits, wombats, squirrels, groundhogs, raccoons, birds, and bats. +++ And humans! Even though our hair is vestigial rather than a full coat.
The average amount is hair on human heads is 100,000. Blondes have more hair than other hair colors at 140,000.
Bears are mammals because they have hair or fur, give birth to live offspring (rather than laying eggs), and feed their young with milk produced by mammary glands. Additionally, bears are warm-blooded, meaning they can regulate their body temperature internally.
Yes, mammals are the only animals with hair, or at least, the only ones with the kind of hair that you are thinking of. Mammals have a particular kind of hair, which is made out of a protein called keratin. There are other animals who have other kinds of hair. Insects have their own kind of hairs, which are sensory rather than protective in nature, and they are made of a different protein known as chitin.
Mammals are different than other animals for a few reasons, but the main one is the presence of hair or fur. Another reason is that mammals have mammary glands.
(1) Only mammals nurse their babies on the mother's milk. (2) Only mammals have hair. (3) Mammals are warm-blooded. Birds are warm-blooded, too, but nearly all other animals are coldblooded. (4) Mammals have a larger, more well-developed brain than other animals. (5) Most mammals give their young offspring more protection and training than other animals.

A krill is actually a very small crustacean, which is found in oceans and other bodies of water. They are not mammals, which usually are covered in hair.
"hair becasue they are mammals" This is actually a horrible explanation. Humans are mammals because we have hair. Dogs are mammals because they have fur. Camels are mammals, and the numerous sources I've viewed indicate that camels have hair, rather than fur. Again, to say, "hair [because] they are mammals," is rather ignorant to the definition of "mammal." All mammals have hair or fur.

We have hair because we are mammals. Mammals are air breathing, hair on bodys, and we dont lay eggs. Except for the pladipus. our hair is fur. its just sometines longer than fur. our hair is like a lions mane. its still fur.
Warmth Bear in mind that even though the amount of hair you have on your legs may not really make any difference to your body warmth, it is an evolutionary vestige of earlier species that had more hair, and which had no other way to keep warm than their own hair.

There is no reason other than that Guinea Pigs evolved to be mammals.
Mammals are the animals that typically have an outer covering of hair. This hair serves various purposes such as insulation, protection, and camouflage. Examples include dogs, cats, bears, and rabbits.
