My idea is that if the evolutionary theory is correct, and that their are planets that can support life, that the dominant species of those planets would be reptilian. The reason I say this is because scientists say that reptiles and dinosaurs were the most dominant on this planet before the mass extinction by the comet or volcanic eruption. If a different planet had went through the evolutionary steps as earth did, and didn't have a mass extinction, then reptiles would be the most dominant species. And since they would be the most dominant, that means they would have went through millions of years of evolution, so who really knows how these creatures can modify their body or do anything special? Any ideas/thoughts/or suggestions?
