Question

11.4. give one example of a homologous trait and one example of a vestigial trait, and explain how such traits support the theory of common descent. complete the following passage describing how scientists use physical traits to help determine evolutionary relationships. when two species share a number of homologous traits, it is evidence that they share a recent common ancestor. vestigial traits are those that in an organism. the presence of vestigial traits can also help determine relationships between species that possess homologous traits that are obvious, are no longer present, large, no longer function, small, still function

Explanation:

Homologous traits show recent common - ancestry. Vestigial traits no longer function. Their presence helps in evolutionary relationship determination.

Answer:

When two species share a large number of homologous traits, it is evidence that they share a recent common ancestor. Vestigial traits are those that no longer function in an organism. The presence of vestigial traits can also help determine relationships between species that possess homologous traits that are obvious.
