Here’s a section all about the animals that are most like you—that’s right, mammals. Let us tell you a little about yourself and other mammals. Mammals are warm-blooded animals that have mammary glands and a four-chambered heart. They give birth to live young (as opposed to laying eggs) and are either partially or completely covered in hair. The teeth of most mammals come in a variety of shapes and sizes designed for chewing many kinds of foods. (Humans, for example, have incisors for cutting, molars for crushing, etc.) Plus, mammals have larger brains than other vertebrates of equal size, making them most capable learners. Which is why you were able to read that last fascinating fact. There’s much more to know about mammals, so spend some time in this section acquainting yourself with these animals.
