Question

If two modern organisms are distantly related in an evolutionary sense, then one should expect that______________. A) they live in very different habitats.B) they should share fewer homologous structures than two more closely related organisms.C) their chromosomes should be very similar.D) they shared a common ancestor relatively recently.E) they should be members of the same genus.

Answer 1

Answer:

Option B

Explanation:

They will be distantly related in that they share fewer homologous structures than closely related organisms. These distantly relatéd organisms may be unrelated but yet appear alike, this can be explained as the case of common adaption to similar environmental conditions becoming evolved in both but they are still distantly related. For example, the the wings in a bat, insect and birds. These are distantly related but the wings perform the same function, almost have a similar form but their embryonic origin is different meaning this three organisms do not share a common ancestor that had wings.

Answer 2

Answer:

They should share fewer homologous structures than two more closely related organisms.

Explanation:

Organisms that share similar environment have the tendency to share similar physical features. This process is known as convergent evolution.

Convergent evolution is the process in which organisms that are not closely related, independently evolve similar traits as a result of these organisms having to adapt to similar environments or ecological niches.
