Humans share several features with salamanders.Certain genes and proteins are nearly identical between the two species; both species have four limbs with a similar skeletal structure; the species' early embryos are very similar; and where the salamander has a functional tail,humans have a vestigial tailbone.In evolutionary terms,these are examples of

Question

Quizplus · Accepted Answer

The fact that humans and salamanders share several features, such as similar genes and skeletal structures, as well as similarities in early embryonic development, indicates that these features are the result of homology. Homology is the sharing of common ancestry that results in the development of similar traits or structures. In this case, both humans and salamanders inherited these features from a common ancestor.
