Is there Cambrian explosion? The anwser is : we don't know. According to the recent study, the reason why there is not much animal fossil found before the Cambrian is because the animals haven't evolute the harden part of their body tissue yet. So most of the animals lived in that period havn't preseve as fossil. However at the edicaran biota, we found many sinian animals and some of them resemble to the latter animals like trilobite and jellyfish. So the animals in the cambrian period may not b appear studdenly. Beside the evolution is proved by the genes of birds which can express the character of dinosaurs. If there is no evolution, why should they chicken contain the dinosaur genes?
