Segmentation is the secret behind the extraordinary diversification of animals.

"The researchers found that the genes controlling segment formation during embryo development are almost the same in drosophila (an arthropod) and in annelid marine worms, on which they concentrated their studies. These similarities led them to conclude that the genes had been inherited from a common ancestor, which was itself segmented. It also appears that vertebrates inherited this characteristic from an ancestor they share with the arthopods and the annelids. This is what the researchers are now seeking to confirm.
This work supports the idea that segmentation only appeared once in the history of evolution and that it led to the broad diversity of animal groups possessing it."
