Why do a chicken embryo and a cow embryo look very similar even though the adults do not?

Question

Why do chicken embryos and cow embryos appear very similar during their early development, even though the adult forms are quite different? While these species are not closely related, they share similarities in their developmental processes. This raises the question of how their embryonic development can be so alike despite their distant evolutionary relationship. Is it due to shared genetic traits, or do the embryos undergo significant changes in utero that lead to the distinct structures seen in adulthood?

Answer;-They are distantly related, so their development is similar.Explanation;-Comparative embryology is the branch of embryology that compares and contrasts embryos of different species. It is used to show how all animals are related. Many things are compared (such as whether or not the organism has a notochord or gill arches). -Embryology proves the modern theory of evolution by the similar structures found in embryos. The greater the similarity in structure, the more closely related the species are and the more recent their common ancestor is.

The correct answer is 2nd statement. Explanation:Both the chicken embryo and the embryo of a cow look quiet identical as they both are distantly associated, and thus, it can be concluded that their development would be identical. The development of both the cow and chicken at the beginning similarly takes place. The resemblance in the development of both the embryos is the same because of the similarity of both ancestors.  This suggests that both the chicken and cow have originated from a similar organism, and then afterward got diverged into distinct species. It has been found that the organism that exhibits the same kind of embryonic development demonstrates similar ancestry.

The correct answer is they are distantly related, so their development is similar.The chicken and the cow are initially developed in a similar way. The similarity in the embryonic development is similar due to similarity in ancestor. It indicates that the chicken and the cow are developed from the same organism and lately diverged into different species. It is said that the organism, which have a similar type of embryonic development shows the same ancestry.

Correct "They are distantly related, so their development is similar."All animals came at some point from a common ancestor accordingly to the evolutionary theory of the organisms. So, this means that both cow and chicken are related, distantly related. They may have had a common ancestor. Although nowadays these two animals may seem quite distant, their embryological development is quite similar because of this common origin of both animals.

They are distantly related, so their development is similar.Chicken and cows are distantly related by many thousand years ago. The reason of these morphological and physiological differences that occurs later in the development is because of evolutionary biology. Despite this occurrence, almost every organism starts from a gamete to zygote to embryo and etc later on.

They are distantly related, so their development is similar.There's a phrase in biology called "Ontogeny recapitulates Phylogeny." This means that in embryonic development (ontogeny), genetic relatedness (phylogeny) is expressed.

I think the question needs to choose one from the last four lines. They are distantly related so their development is similar. They have different genetic materials. But they have similar structure of body. So they have similar embryo. And they are both vertebrate.
