Why did the warmblooded and coldblooded are difference?

Answer 1

Warm blooded animals are able to produce body heat, and can be active even in extreme cold. Mammals are warm blooded. Cold blooded animals become torpid and may even hibernate during cold weather. For example: a snake (reptile) is cold blooded and needs to bask in the morning sun to warm up before becoming more active. Frogs and toads will bury themselves in the mud of a pond to escape being frozen during winter.
