Enamel is responsible for giving out teeth some bite, and now scientists may have worked out where it originates from.

A team of researchers have revealed that new fossil and genetic evidence suggests that enamel in fact evolved from the scales of ancient fish which swam the seas around 400 million years ago. Scientists have long puzzled where enamel came from before becoming part of our teeth.

In the body of humans and other vertebrates, enamel is the hardest tissue. Now scientists may be able to explain where it comes from, using the fossils of two primitive fish.

After examining the bony fish from the Silurian Period, they found enamel coating on their scales...
