Question

Which of the following statements about descent with modification is false?

A. Any two species share some characteristics because they descended from a common ancestor that lived at some point in the past.

B. Over time, evolution by natural selection causes organisms to accumulate differences from their ancestors.

C. All similarities between organisms result from descent from a common ancestor.

D. Organisms that share a more recent common ancestor are likely to be more similar to one another than are organisms that share a distant common ancestor.

Answer 1

Choice C is false.

Explanation: According to the evolutionary biologists, the descent with modifications is dependent upon the biological features, genetic inheritance as well as the environmental conditions in which the similar of different kind of populations reside in. However, all of these similarities are undoubtedly not dependent upon a common ancestor. These similarities might arise due to common environmental conditions as well. For example, people residing at very high altitudes all over the globe have similar biological features, although they do not share a common ancestor.
