Which conclusions can be made about the animals of each class based on the structural similarities of the embryos? select all the correct answers. 1.there is an evolutionary link among the classes. 2.the adults of each class may share structural similarities. 3.reptiles must have given rise to fish and amphibians. 4.animals of each class have analogous structures.

The correct answer is option 1, that is, there is an evolutionary link between the classes.  

The study of one kind of proof of evolution is known as embryology, that is, the study of embryos. An embryo refers to an unborn young in its initial stages. Embryos of various distinct types of animals, that is, mammals, reptiles, birds, fishes, etc. seems very identical and it usually becomes tough to differentiate them apart.  

Various traits of one kind of animal are observed in the embryo of another kind of animal. This illustrates that the animals are identical and that they are developed identically, signifying that they are associated, have common descendants and that they began the similar, slowly developing distinct traits, however, the fundamental plan for the beginning of the creature remains similar.  

Answers are 1) There is an evolutionary link among the classes. 2) The adults of each class may share structural similarities.
