Embryos of different species look very similar, which shows that the organisms share a ancestor.

Hi!

The answer would be common.

Embryos have been closely studied as evidence of evolution, and this study is known as embryology. During embryo development, it is observed that the embryos of fish, mammals, reptiles, birds and all have remarkably similar structures with only minor distinctive features.

An example of such a feature is the presence of gill slits in both humans and fish in embryos. Now in fish, this part gives rise to gills which are particular to fish, but are seen to disappear before birth in humans.

The developmental similarity is suggestive of the fact that all species are related, and at some point in the scheme of evolution, diverged from a common ancestor.

Hope this helps!
