The morphology of Alligator mississippiensis, American Alligator, allows for various people to conclude that this species has existed for thousands of years. The American Alligator is a keystone species in marsh ecosystems located in the Southeastern United States. One reason the American Alligator is a keystone species, is the fact that it has evolved a mechanism for when water levels are low. The alligator digs holes that retain water during dry periods. This mechanism is also a popular and vital habitat for survival of other animals located in that biome. The American Alligator is an interesting species when studying evolutionary biology because of their physical experience, such as body armor, and their …show more content…
The American Alligator provide foraging and refuge areas for both plants and animals during the dry season. The alligator is able to do this by digging holes, which retain water, and range from only a few to several meters in diameter. In this research studies, the scientist investigate the spatial distribution of alligator holes and whether this species is starting to use canals as refugee and foraging areas rather than using alligator holes.

Molecular Characterization of Dental Development in a Toothed Archosaur, the American Alligator, Alligator mississippiensis This article looks at the teeth of American Alligator and how these species evolved to have specialized teeth. Reasons for teeth to evolve into different tooth types is because the diet of these species could have changed over time. This could either be because of limited resources or their prey has adapted mechanisms to help prevent
