Biology students are examining the diagram below, which shows four vertebrate embryos at the same stage of development. The students are asked, how do the embryos provide evidence for

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.
