Explanation:
1.Best similarities appear in stage 1 and stage 2. In embryonic development, STAGE 1 shows similarities as the structure of the various animals, such as cats, birds, fish, lizards and humans, appeared the same.
2.Fish embryos go through a process called mid-blastula transition which is observed around the tenth cell division in some fish species. Once zygotic gene transcription starts, slow cell division begins and cell movements are observable. During this time three cell populations become distinguished.
3. a different structure like forelimbs, their sizes as well as eyes begin to appear. Further Explanation: An embryo refers to the early phase of development in organisms. ... The progressing developmental stage ensures that the organism develops and matures into a fully developed individual.
4.yes it can be evidence that evolution takes place, the evidence of structure and studying of their molecular structure may suggest that they are related to each other.
