Question

In the earliest stages of development the embryos of a fish, calf, human, and tortoise all look similar. In the next stage the calf and the human look most alike. What assumption can be made based on this similarity?

The Answer is D

Answer 1

The assumption that can be made based on this similarity is "Out of the animals listed, calves are most genetically similar to humans."

Step-by-step explanation:

A phylogenetic tree can be described as a diagram which represents the evolutionary similarities and differences among different organisms. It tells which organisms have some common ancestor in common.

The similarity between the early stages of development in the fish, calf, humans and tortoise embryo show that they might have common ancestors. Further similarities between the calf and humans show that they are more similar to one another as compared to the other species.
