The students are asked, how do the embryos provide evidence for organic evolution.

Explanation:

The embryos of different vertebrate groups have been found to have similar morphological features during the early stages of development. This similarity suggests a common ancestry. The closer the resemblance between the embryos in early stages the closer the phylogenetic relationship of the organisms.
