What is a Mammal?

Mammals have two unique characteristics, the presence of fur or hair and mammary glands where milk is produced to feed the young.

Mammals are thought to have evolved from the Cynodonts which arose during the Permian. These possessed both reptilian and mammalian characteristics. It wasn't until the late Triassic that the first mammal Adelobasileus arose.
