In the old world, placental animals become the dominant mammal, but in Australia, placental animals ruled.24 Are we living in a Scientific Revolution? How is evolution used in biology? These animals evolved together in similar climates before the continents split a few hundred years ago. The only examples of parallel evolution that I know of are the parallel evolution of placental and marsupial animals. The animals developed similar quill structures even though they live in different parts of the planet and are completely different species. The only examples of convergent evolution I know about are the case of echidnas, hedgehogs, and tenrecs. It is so crazy that two species form opposite parts of the world will evolve with similar features, or that similar species will develop similar traits in completely different habitats. I was always interested in lectures about things like convergent and parallel evolution. In some of these cases, I think that the species still alive evolved separately from the extinct species, but shared things like body types and features.Įcology and evolutionary biology are so cool. I think there are also a number of extinct animals that share similarities with animals still roaming the earth today. Many of the wing patterns and colors are shared between different species of butterfly. From what I know about evolutionary biology, butterflies offer one of the best examples of parallel evolution.
