Prehistoric fish have teeth like humans

Scientists have found that prehistoric fish 400 million years ago began to have teeth like mammals.

A group of international scientists from the UK, Switzerland and Australia used the latest high-energy X-ray equipment to test fossils dating to about 380 million years of the prehistoric Compagopiscis species. discovered in Australia.

After constructing a 3D model of the Compagopiscis prehistoric species from X-ray images, the scientists were surprised to find that this fish has developed both jaws and teeth like existing mammals. great.

This finding means extremely important, because it shows that humans can develop teeth and jaws much earlier than we previously meant. This also means that humans can evolve faster.

Previous studies suggest that humans first developed jagged jaws to tear raw meat and then develop complete teeth. These vertebrate animals only develop teeth and jaws about 7 million years after the extinct Compagopiscis fish.

However, if a species of fish considered to be an ancestor of humans began millions of years earlier than we mean, then the first vertebrate species will develop teeth sooner. .

'This is evidence that teeth appear in the first vertebrates and help clarify the debate about the origin of teeth,' said Professor Philip Donoghue, a member of the research team from Bristol (England). ), said on the Daily Mail.
