Why is it carnivour have their teeth all thier lives while humans don't?

Question

humans when getting old almost lost all their teeth far before life span.

Answer 1

It is because carnivores in the wild die without teeth. Pretty simple.

Answer 2

In the wild, animals do not generally die from "old age" - they get slow and they die. If people died when they started getting slow, they would die long before they were 90, and long before they started losing their teeth.
If you have a house cat, they will live their full lifespan - that same cat in the wild will not live nearly as long, only a few years - if that. They will not have a chance to get old, slow and toothless. People have that luxury. Nothing is going to eat us when we're middle aged with sore knees - so we live long enough to lose our teeth. (Anyone who's ever had an old cat can tell you that they DO lose their teeth - they can also go blind and get arthritis, just like any other old animal)
Oh, and humans are omnivores, not carnivores. :)

Answer 3

Hmmmm...my great grandmother is 96. She has just about all of her teeth.

My Siamese cat died when she was 21.She had lost all her her teeth by age 17.

Other animals keep their teeth longer because they eat the right things for how they have evolved. They have to evolve with good teeth to compete. Humans these days don't eat right or take care of their teeth properly. Besides humans are not carnivores and we don't have to compete for food.

Answer 4

These organisms loose teeth as they get older also, but unless they are in captivity they starve and die.

Answer 5

i exactly do not know the scientific reason...........
but i think that may be due to the continuous use of their teeth for thier daily activities like hunting killing etc due to the daily use their teeth may be strong
