User blog comment:Gary3008/A study on Dinosaur Puffles/@comment-3169402-20140118210339/@comment-24096114-20140119123152

The first species were bacteria forms which then evolved through the Palaeozoic. Era to become small sea lizards later moving onto land and then dinosaurs. Some dinosaurs were then growing feathers and that is how birds evolved. Penguins, in the virtual universe of CPm were some of the first birds as they were known as caveguins and developed a language during the Mesozoic. Other branches of these reptiles evolved into mammals like modern day puffles. Crabs and other crustaceans are completely different and are invertebrates rather than vertebrates (mammals, birds, reptiles, etc.) so I believe neither theories are correct when put against scientific research. Maybe we will find out when we go back to the Cretaceous next week!
