Why are teeth absent in birds?
Previous research in this area concluded that birds – which are the living descendents of dinosaurs – lost their teeth as part of the evolutionary advantage of improved flight.
Are there any other animals that have baby teeth?
Do other animal species have baby teeth and adult teeth, like humans? For sure. As with humans, you can tell an ape’s age by looking at its teeth, says Erin Stromberg, primate keeper at the Smithsonian National Zoo. In fact, most mammals have two sets of teeth in their lifetime.
Why do some animals have fewer teeth than others?
This equips mammals to really mash up their food, which increases the food’s surface area and enables them to absorb more energy and nutrients. “Fewer teeth mean [s] they can focus on very precise types of contacts, and interactions, between opposing teeth” and thus maximize on energy consumption, said Peter Ungar,…
Which is the least toothy animal on Earth?

What is the only mammal without teeth?
Out of all the mammals on earth, there are only two groups that don’t grow any teeth: pangolins and anteaters. Because they don’t have any teeth, they have no way to chew their food. Fortunately, both groups of animals don’t need to chew. Instead, they have long sticky tongues for capturing ants and other insects!
What animal has only one tooth?
Diphyodonts also differ from monophyodonts which are animals who have only one set of teeth that do not change over a long period of growth. In diphyodonts, the number of teeth that are replaced varies from species to species.
