Question

The diagram shows the embryo development of four vertebrates and suggests all of the following EXCEPT

Answer 1

Answer:

The correct answer would be B) there are no similarities in the embryos of all four groups.

There are similarities in various stages of the embryonic development of different species. They look very similar in the early stages of development. The ancestors of the different animals are same and this implies that they are related.  

For example, the embryo of both human and fish has gill slit but in the later stages, the gill slit of human embryo disappears. The difference in later stages shows the evolution of different traits but the beginning of creatures are same.

It is why comparative embryology is also used to provide evidence of evolution.

Thus, the development of four vertebrates and suggests all of the following EXCEPT there are no similarities in the embryos of all four groups.
