Question

read the information before answering the question. the observation of embryological similarities among different species best supports which of these ideas? species em yotic stages have nothing to do with evolution. species share a common ancestry and have evolved over time. species were created independently with no evolutionary connection.

Explanation:

Embryological similarities among different species are evidence used to support evolutionary theory. If species had no evolutionary connection (created independently), we would not expect such similarities in their embryonic stages. Also, the idea that embryonic stages have nothing to do with evolution is contrary to the evidence from comparative embryology. Comparative embryology shows that as embryos develop, the similarities can indicate a common ancestry. For example, vertebrate embryos (like those of humans, chickens, and fish) have similar structures (such as gill - slit like structures in early development) at certain embryonic stages, which can be explained by a common ancestor and evolutionary divergence over time.

Answer:

Species share a common ancestry and have evolved over time.
