The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.

The same kinds of cells that grow in similar patterns in different but related organisms produce?
The same kind of embryos
How do embryos support the Theory of Evolution?
By monitoring how and what an embryo grows as it matures, you can see a lot of things that you cannot see in a fully grown animal. For instance, human embryos have a tail at certain stages in development. They also surprisingly have gills at one stage. Two of these pairs of gill slits disapear as the embryo grows, and the final pair move upwards to become your eustacian canals and ears. This shows us that humans once had tails and that hundreds of millions of years ago we also had gills, which means that at some point in our past we were once sea dwelling.Embryology shows that organisms look the same at their earlier stages. This supports evolution. Evolution is the idea that many organisms have a common ancestor, and that is why they have similar traits.The stages of development of the embryos of different organisms are extremely similar, thereby suggesting common ancestors.
How are embryos used as evidence of evolution?
this is because they have a link with early ancestors of similar structure.
How do the embryos of different species support the theory of evolution?
The morphology of embryos at various stages, and even the developmental patterns of embryos, show the same pattern of nested hierarchies that we find in morphology, behaviour and genomes, independently confirming common descent, but also teaching us how morphologies could diverge through relatively minor genetic shuffling.
How embryology is used to study evolution?
Embryology is used in evolution because its shows a common ansetor. For example, a human and fi sh have similar embryos. Both embryos have pharyngeal slits. In a fish those develop into gills. In humans those turn into our ears.
How embryos help identify a common ancestor of different organisms?
we compared their bone.
What is suggested by the similarity of early embryos of different species of vertebrates?
evolution from a distant common ancestor
Do all organisms start out as embryos?
No, not all organisms start out as embryos. Embryos are typically seen in higher animals that undergo sexual reproduction, where a fertilized egg develops into an organism. Organisms like bacteria and protists reproduce asexually and do not have an embryonic stage in their life cycle.
The same kinds of cells that grow in similar patterns in different but related organisms produce?
The same kind of embryos
Do embryos of many different vertebrates look much more similar than the adult organisms?
yes
How are vertebrate embryos evidence of evolution?
All vertebrate embryos look roughly the same, showing that they come from a common ancestor.

What do all vertebrate organisms have in common when they are embryos?
pouches
Why does comparative embryology show similarities between organisms that do not appear to be similar as adults?
Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. All of the animals except for fish, lose their gills slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage
How can embryonic development can be used as evidence for evolution?
Related species have similar embryos.
How has the early stages of development in embryos evidence of evolution?
stoned monkeys rule the world
How are embryos used as evidence of evolution?
this is because they have a link with early ancestors of similar structure.
