It is obvious that the coelophysis evolved to the archaeopteryx, and then to the pigeon based on their foot bone structures. The coelophysis has four thin phalanges with the smallest one extending the most and the third finger being the longest. In the archaeopteryxś foot, it also has four thin phalanges. The shortest is the first and is sticking out, whilst the third is still the longest. Although the phalanges are even thinner. The pigeon, has four thin phalanges as well. Even though they are more spread apart, the first is sticking out more and the third is still the longest.

The Alligator is more closely related to the Archaeopteryx than the insect is. It is related more because the Alligator also has Vertebrates which the Archaeopteryx also hase but the insect does not. So this is why the Alligator is more closely related to the Archaeopteryx than the insect is.
