The 'Murican Alligator A project contrived and assembled by Zach wedel

The Skull of an American Alligator

Some background, the American Alligator or the Alligator Mississippiensis by it's scientific name, is a large scale reptile found easily south of the United States, hence it's name (Louisiana, Mississippi, Alabama, Georgia, and Florida) and at size yields to be 10-15 feet and averages to around 1000 pounds, and as for females they measure 9.8 feet in lengths and weighs in around 700 pounds. They also have a carnivorous diet and have an average life span of 35-50 years. The American Alligator or alligators in general love to live and frolic in swamps and marsh-like areas

B. Homologous Structures

Proof that Alligators are related to creatures you would be surprised to know...

Homologous structures are bone structures that are very identical but have a different purpose. Let's take a bird and a human for example, they both have identical bone structure. However, birds fly, and humans don't. Of course, 'Murican Alligators have been proven to relate to humans, penguins, and bats. Therefore, they all have a common ancestor, which we don't know exactly who...

Chart that projects how close alligators and crocodiles are related to other animals.

Morphological/Molecular Evidence. Did you know that birds are primarily related to alligators? Nether did I! In 2004, a team of scientists at UC Santa Cruz discovered that birds are most related to alligators due to their molecular and morphological correspondence. Morphological evidence is evidence that proves two different animals have evolved in a similar matter due to a common ancestor. Therefore, the American alligator and birds have a supposed common ancestor that was believed to live around 240 million years ago. It has also been proven that alligators and birds have similar vocal structures. Scientists aren't exactly sure how similar birds and alligators are, but it has been estimated that they are ~93% similar to each other

Comparative Embryology

Phases of the 'Murican Alligator's time in in an egg before it is born...Nothing much else to say

Alligators in general have a very unique hatching evolution. It is also worthy to note that the #1 cause of human- alligator is protection of young.

Vestigial Structures. Vestigial Structures are obviously structures that animals have but don't use. However, their ancestors did at one point. The American Alligator's first and second ancestors supposedly had horns in the back of their eyes. The reason they have this is still unknown, but it definitely proves that Evolution occurred.

Transitional Fossils


These two reptilian creatures are obviously ancestors of the american alligator due to their uncanny similarity. However, if these images were compared to a modern alligator, then it proves that alligators snouts have grown almost twice their size. Their diet also changed as they used to eat only crustaceans.
