True.
the species come from a common ancestor
The early embryos of all animals have a very similar appearance. This is no different for chicken and pig embryos.
Actually yes it can. Embryos, DNA sequences, and fossils amongst others things can help show similarities within species. This can show that those species have similar traits because they evolved from a common ancestor. But those differences show why they are different species and thus evolving.
Depending on what animal because animals are very different from one another, but that would mean you are considering humans not animals.
i dont know hahahha
what is Similar structures that related species have inherited from a common ancestor
similar chromosomes make them up.
Related species have similar embryos.
Badgers are similar to mammals such as weasels and skunks. They are all burrowing mammals that have flat, elongated bodies.
The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
homologous structures
this is because they have a link with early ancestors of similar structure.
