1. Silurian, Carboniferous, Jurassic, Eocene, Miocene 2. Fossil Evidence, Genetic Evidence 3. Being that the first birds and mammals, as well as gymnosperms appeared during the Mesozoic Era, the character likely evolved 245 million years ago. 4. It would be Analogous because of convergent evolution. 5. Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Carnivora, Family: Canidae, Genus: Canis, Species: C. lupus (Dog) 6. see attached page 7. The ability to reproduce and survive in an area means a species does not need to adapt or evolve. Unchanging ecological conditions result in this long-term stasis. 8. Geographic isolation plays a big role. A subset of a population can be geographically isolated by a variety of mechanisms.

Unformatted text preview: Examples might be a river altering it's course, rifting (formation of the African Rift Valley resulted in rapid speciation/ diversification), or formation of new mountain ranges to name just a few. Formation of new ecological niches also plays a big part. Extinction events that left many niches vacant have been major drivers for subsequent biodiversification and rapid speciation. The most famous event was the mass extinction event at the end of the Cretaceous period but there have been many such events. A much larger one, in fact, occured at the end of the Permian period. Rapid climate changes also create new and different ecological niches to be rapidly filled. Glaciation is an example....
