Which statement concerning the evolution of species A, B, C, D, and E is supported by the diagram below?

• Species B and C can be found in today's environments.

• Species A and D evolved from E.

• Species A and C can still interbreed.

• Species A, B, and E all evolved from a common ancestor and all are successful today.

According to some scientists, patterns of evolution can be illustrated by the diagrams below.

• The organisms at the end of each branch can be found in the environment today.

• The organisms that are living today have all evolved at the same rate and have undergone the same kinds of changes.

• Evolution involves changes that give rise to a variety of organisms, some of which continue to change through time while others die out.

• These patterns cannot be used to illustrate the evolution of extinct organisms.

This diagram suggests that

• different groups of organisms may have similar characteristics because of common ancestry

• because of biochemical differences, no two groups of organisms could have a common ancestor

• evolution is a predictable event that happens every few years, adding new groups of organisms to the tree

• only the best adapted organisms will survive from generation to generation

The most likely explanation for the branching pattern seen in the circled region labeled X is that:

• environmental changes resulted in extinction

• speciation occurred as a result of inbreeding

• no speciation occurred during this time

• environmental changes influenced speciation

Which statement best describes species E?

• Species D is an ancestor of species E.

• Through natural selection, species E produced increased survival mechanisms.

• Species E had greater success due to patterns of behavior.

• Species E had insufficient adaptive characteristics for survival in a changing environment.
