What do we have in common with a bear, a mole, a squirrel...or even a bat? Were all mammals.
Humans are just one of the 4,000 or so different species of mammals on our planet.
Mammals have three characteristics in common:
they have fur or hair;
they are warm-blooded, which means that they maintain a constant body temperature rather than adjusting to the temperature of their surroundings;
in the first few weeks or months of life, mammals are fed on milk produced by their mother.
Most people live in a building - their home. At home, you're in your
natural habitat. Different
mammals make use of many habitat types. Some mammals live in the desert,
while others live in wetlands. Some mammals such as dogs and cats,
often share your home. Forests, young and old, large and small, are
one of the primary habitats for many mammals.
