Why does embryology suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common.

In the examination of the embryological stages of various organisms, it appears to be very similar in their structure, for instance, all vertebrate embryos have gill pouch and that evolved in gills in fish and head and neck in others.

The tail of the vertebrates is also an example that is present during the embryological stage but later regressed in human and other have them. On this basis, it can be stated that embryology suggests an evolutionary relationship.

explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
