Why birds don’t have teeth and the answer is surprisingly interesting

Have you been terrified of the human-like teeth of freshwater monsters such as Pacu fish, Piranha fish …, or deeply impressed with the snail’s up to 15,000 tooth count.
We know that most animals have teeth, but one species we are familiar with doesn’t have teeth – it’s the bird!

Why Don’t Birds Teeth? So don’t hesitate to find out now!

According to the Telegraph, research carried out by experts at the University of Toronto (Canada) has shown that the ancestors of modern birds survived the weather catastrophe more than 60 million years ago. And this “longevity” is due to the structure of the hard beak, which helps them eat the seeds.

The meteoric catastrophe hit the Earth which made food sources extremely scarce, climate change … It made carnivorous dinosaurs, lizards, including species of the Maniraptoran family. (dinosaur family, including birds) was abruptly wiped out at the end of the Cretaceous Period.

But strangely, birds with beaks but no teeth survived the great extinction. The question is, why is there this difference?

To find the solution, the experts analyzed data from more than 3,000 fossil tooth samples from 4 groups of the Maniraptoran family.

They suspect that the diet played a role in the survival of the modern bird’s ancestors at the time.

As they continued their research, they discovered the food used by modern avian parents – nuts. What modern birds have in common, however, is that they have a beak but no teeth.

So, now do you understand why today’s birds don’t have teeth? Because toothed birds are already extinct.
