AmphibiansElaborate thoroughly: What insects are expected to have the most sclerotized heads? Explain. Does an exoskeleton have an impact on this importance?Describe the evolution of mammals, tracing their synapsid lineage from early amniote ancestors to true mammals. How would you distinguish pelycosaurs, early therapsids, cynodonts, and mammals?
- fossil bird salamander 2. This fossil bird and this living salamander both have tails. However, they have different tail structures. The bird has a very short tail made of just one bone that helps it have a light skeleton for flying. The salamander has a long tail with many bones that helps it balance while it runs. What most likely explains why both the bird and salamander have tails and why the tails are different? a) The salamander and bird both inherited tails from a shared ancestor population, but this population separated into different environments. In each environment, different types of tails evolved, which helped the populations survive. It is impossible to explain the body structures of different species. The way that structures change over time is very complex, and no one has ever observed these changes occurring. The bird and salamander are different species, so they do not share an ancestor population. These species had separate ancestor populations, and each evolved a…b) How would you distinguish pelycosaurs, early therapsids, cynodonts and mammals? Expound.In your own words: In which ways does the limb orientation of "advanced" tetrapods differ from that of "primitive" tetrapods?
