The world's first insect

Abstract

If we could visit the earth more than 400 million years ago, to see the first insect, ancestor of all the millions of species of insects that live today, what would it be like? How did that first insect behave? What did it eat and who were its enemies? Incredible as it may seem, we can answer all this and even more: DNA analysis indicates that today there is an animal that profoundly resembles that first insect, and you can see it with your own eyes!
