Morphological and Molecular Evidence- The closest relative of the Mexican Grey Wolf is considered the North American Gray wolf. The Gray wolf is an ancestor of the domestic dog.The Mexican Grey wolf is a subspecies of the North American Grey wolf that was once native in Arizona, New Mexico, and Texas. Design of fur on the back is the same. Both wolves having the resemblance of a German Shepherd. Broader skull and long ears.DNA is passed down through the mother's blood line, genetically wolves and dogs are 98.8% identical. This evidence shows evolution in my animal because genes are passed down from generations. They can have the same DNA but different names.

Homologous Structures- The Siberian Husky, Humans, Bats, Canines and whales all have the same forelimb structures. Four different bones that are put together in a similar way. All structures look different and function in a different way than another organism. A Homologous structures is an example of an organ or bone that appears in organisms but have a different function. They are closely related but have evolved at different times.

Vestigial structures- The wolves have a structure that is called Dewclaws. Dewclaws are short nails or claws on a dog that don't touch the ground. Non-functional part of the wolves body they serve an early ancestor of huskies when they would climb trees.They're only 4 claws that touch but not 5.Vestigial structures are genetically determined that have lost some of the ancestral function but remain during the process of revolution. Shows evolution because it shows what ancestor canines used Dewclaws for and how they adapted to environment.
