I think it's because the way our body is formed from the so called, "First humans" on earth. and by that, the first humans have to be warm blooded to keep warm. they didn't have lots of shelter, and so they had to be warm. They did have hair, but they needed more than that. That's how our body works. But it is not important that mammals have to be warm blooded.
Birds and mammals are called warmblooded animals because their bodies temperature stays steady (as long as their healthy), 36.6 degrees celcius. Coldblooded animals, like reptiles, adjust their body temperature to whatever temperature they find themselves in (so the body temperature of a frog should be about the same temperature as that of the water its swimming in). Warm blooded animals need a steady temperature for a lot of systems in the body to run correctly (that's why when you have a fever, you're often not hungry-- your digestive system works differently than normal). I hope it answers your question!
Except for Mammals and Aves all other organisms are cold blooded.
White tigers are mammals which are all warm blooded. According to Rick James, certain women may be cold blooded, but that is another matter.
Mammals are warm blooded because we are mammals and we are warm blooded
Birds and Mammals come to mind . . .
Mammals are not cold blooded.They are warm blooded.
there are no cold blooded mammals no there are no cold blooded mammals
The bilby is warm blooded. It is a mammal, and all mammals are warm blooded.
they are warm blooded mammals are warmblooded.
All mammals are warm blooded (endothermic)
Cats are warm-blooded, as cats are mammals, and all mammals are warm-blooded.
Warm blooded. They are mammals, which feed breast milk. All mammals are warm blooded.
