What is the value of a transitional fossil?

A.Transitional forms show the evolutionary steps between species.

B.Transitional forms are analogous fossils.

C.Transitional forms discredit the theory of evolution.

D.Transitional forms are proof of punctuated equilibrium in evolution.

A

Answer: A.Transitional forms show the evolutionary steps between species.

Fossils are dead remains. Organisms leave imprints upon death and these imprints are preserved in sedimentary rock. A transitional fossil, however, is any fossil of a life form capable of exhibiting common traits between an ancestral group as well as its derived descendant group. These fossils are important as a result of their ability to demonstrate the evolutionary changes occurring between organisms. This can help in displaying seemingly intermediate traits between a common ancestor and all of its descendants.
