Which of the following describes how dna provides evidence to support that life changes over time?
a. some animals exhibit similar structures, possibly due to a common ancestor.
b,. some animals exhibit similar stages of embryonic development.
c. some animals exhibit structures that are no longer used for any purpose.
d. some animals exhibit similar biological proteins.

Option D

Explanation:

The replication of DNA produces a specific type of protein and the protein are functional protein. Specific proteins serve special function.

Pressence of same type of protein in the organism shows that there is a relation between the two organisms having same type of protein.

Both the organisms have same recent common ancestor and that why they have similar biological proteins.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
