Q Why do chipmunks, rabbits, squirrels and beavers have exactly the exact same sort of teeth?

A Erin Flynn, conservation education curator at Henry Vilas Zoo in Madison, Wis.:
Squirrels, beavers, chipmunks and rabbits all have similarly shaped teeth because most those animals have teeth that always grow throughout their lifetimes.
The same as your fingernails grow continuously throughout your life — you need to clip and file them to keep them strong and healthy — these animals have to weigh lots to maintain their teeth sharp and nice.
Maintain their teeth so that they do not grow and they have to take care of. they can keep ingesting, your teeth must be able to fit in their mouth.
Beavers, chipmunks and squirrels are all in the family. Rodents tend to be omnivores, which means that they could eat just a bit of what. Rabbits, on the other hand, are vegetarian (herbivores).
Some rodents are far more technical, like beavers. They have those big teeth that are really perfect for chewing down the trees that they use to make dams, their homes.
A guideline using critters is that form follows function. Should you have a look at the human body and teeth of an animal, you can generally figure out what sort of habitat that they live in and what they eat.
Dog teeth, for example you’d see on dog or a cat, is a indication of a predator. Teeth could be a indication of an omnivore. With something like a beaver that has such powerful teeth prominently it’s always a fantastic bet that it is a chewer.
