Most animals with backbones, vertebrates, have a similar body plan: skull, ribs, two pairs of limbs, tail. What does this sugges
daser333 [38]

The correct answer is E. Vertebrates are all related to a common ancestor

Explanation:

According to biology and evolution, organisms from different species but that share similarities in morphology (body structures) as well as in genetics often have a phylogenetic relationship which means they descend from the same organism or share a common ancestor. This applies to multiple taxonomical levels including classes such as mammals or birds as it has been proved each of this derived from a common ancestor. Therefore, the similarity in the body structure (morphology) in all mammals suggest vertebrates are related to a common ancestor and as they evolved from this, they share similarities not only in terms of morphology but also in genetics.
