People will replace teeth fish beak

In the not very distant future, people may appear mouths like fish beak, scientists believe. This is due to the fact that human teeth are virtually useless.

According to biologists of the University of Sheffield's Dr. Gareth Fraser, increase the length of human life and the modern diet consisting of "soft" consistency of products makes human teeth practically useless device. And as soon as they become an atavism, then after a number of generations even disappear, as has happened with tails, from which people were only the base - the coccyx.

Dr. Frazier believes that instead of the traditional appearance mouth with teeth   a certain similarity   fish beak   in terms of evolution and human biology is absolutely correct. Moreover, in contrast to the teeth, the beak does not rot, crumbling and falling. Scientists call this evolutionary change "logical and practical."

But do not hurry because this forecast to abandon a visit to the dentist - turning mouth with teeth   at fish beak   It would take more than a few million years. So that the prospect awaits except our very distant descendants. This conclusion Dr. Fraser did when studying features of tooth formation in humans and animals.

If human teeth are changed only once (indigenous milk), then some of the living beings, the process operates continuously as needed. Sharks, for example, new teeth grow every 2 weeks. Dr. Fraser argues that identified the cells that are responsible for the constant regeneration of teeth. According to the scientist, nature is very wisely limited the supply of human tooth - ever it is we do not need. (READ MORE)
