Homologous structures (definition)

It's when very different animals have bones that appear very similar in form or function and seem to be related.

FOR EXAMPLE,⇒ The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
