Question

Name any two temporary embryonic structures in vertebrates which provide evidence for evolution.

Answer 1

There were certain structures which were present in the organisms at the early stages. There was evolution which leads to change in certain features. There are still certain structures which are observed in the early embryonic stage such as notochord is the rod-like structure which is present in the larvae of certain vertebrates. There are gill clefts present in the embryonic structures in vertebrates. These structures provide evidence for evolution.
