Here's why:
* Live Birth: Mammals give birth to live young, as opposed to laying eggs.
* Placenta: A key characteristic of mammals is the placenta. This organ connects the developing baby to the mother's bloodstream, allowing for the transfer of nutrients and oxygen and the removal of waste.
* Nourishment: Mammals nourish their young with milk produced by mammary glands.
Examples of mammals include:
* Humans
* Dogs
* Cats
* Whales
* Elephants
* Horses
* Bats
* Monkeys
