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.

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.

What is the importance of adaptation as a mechanism for the survival of species?

Animals can defend themselves against predators and extreme weather by adapting. Numerous birds may conceal themselves under long grass, while weeds, insects, and other creatures can alter their color to blend in. Predators find it challenging to locate them in search of food as a result.

<h3>What are species?</h3>

A species is a unit of biodiversity as well as the fundamental classification and taxonomic rank of an organism in biology. The biggest group of organisms in which any two individuals of the right sexes or mating types can conceive a fertile offspring, usually by sexual reproduction, is referred to as a species. A species can also be identified by its karyotype, DNA sequence, anatomy, behavior, or ecological niche. In addition, since fossil reproduction cannot be studied, paleontologists use the chrono species idea.
