Answer

Answer:

D. Some traits in certain embryos disappear as the embryo develops.

Brief Explanations:

In embryology, it's known that some embryonic - stage traits are lost during development. For example, human embryos have gill - like structures early on which disappear as development progresses. The other options are incorrect: species with similar embryonic traits often have a common ancestor; similar embryonic traits don't always mean similar adult body forms; not all early - embryo traits remain throughout development.
