Question

All of the following examples provide evidence for evolution except

• A. Humans have a nonfunctional appendix located near the junction of the small intestine and large intestine.
• B. The DNA sequence for histone proteins is highly conserved for multiple species.
• C. Most marsupials are indigenous to Australia, but marsupial species such as the opossum exist in the Americas and are not closely related to the Australian marsupials.
• D. Acquired characteristics, such as the presence of a docked tail in certain dog breeds, can he passed along to offspring.
• E. Gill arches are present in all vertebrate species during embryonic development.

Answer 1

The correct option is B The DNA sequence for histone proteins is highly conserved for multiple species.

A. The non-functional appendix is a vestigial organ that was functional in ancestors.

B. The DNA sequence for histone proteins is highly conserved for multiple species as it similar in all the species. So, it does not provide any evidence for evolution.

C. Australian marsupials are an example of convergent evolution.

D. Acquired characters are passed on to offspring and this states the Lamarck's theory of acquired characters.

E. Gill arches provide embryological evidence for evolution.

Hence, histone proteins do not provide any evidence for evolution.

So, the correct answer is 'The DNA sequence for histone proteins is highly conserved for multiple species'.
