share a common ancestor
Explanation:

Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.
<u>Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their differences as they currently exist.</u>
