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 does comparing the embryos of different organisms support the theory of evolution?
The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
How does embryology support evolution?
Through studying embryos, scientists have found that vertebrate animals seem to have a common design, even though their adult forms are different. Arm buds on different species, for example, look the same early on during embryonic development, yet they will develop into very different forms in the adult (a flipper, an arm, a wing, etc).
How does molecular biology support the theory of evolution?
If you look at the gene sequences of a species, you can see a clear homology among the same species. Distantly related species wont have similarity at DNA level. Hence by knowing the molecular level information one can predict the evolution of a species.
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.
Describe three lines of evidence that support the theory of evolution Provide an example for each line of evidence you list?
Fossil Record the ordered array in which fossils appear within layers of sedimentary rocks. Comparative Anatomy comparison of body structures in different species, which give signs of common descent. Biogeography the geographical distribution of species.

How does the existence of different varieties of species support the concept of evolution?
It doesn't. It supports creation.
What argument did Darwin support about the beak size and shape of Galapagos finch species and its relationship with something else?
Darwin used the wide variation of beaks to support his theory of evolution. He speculated that all the different finches had descended from one species and were not different species.

What philosophy do those who support a theory that any attempt to regulate business is the same as blocking the natural evolution of the species support?
social darwinism
When those who support a theory that any attempt to regulate business is the same as blocking the natural evolution of the species support the philosophy?
Social Darwinism

What flexible column of material provides support for vertebrate embryos?
Notochord
How does the geologic time scale help support the theory of evolution?
It shows the process of wich the species eveolved, what are it's common ancestors, how its related to similar species, and so on and so fourth.
How does scientific evidence support the theory of geologic evolution?
I am a geologist and I know of no theory of "geologic evolution". "Evolution" as defined by Darwin describes the origin of species based on the survival of the fittest. This certainly can not be applied to geological processes, although life is integral to geology.
Those who aupported a theory that any attempt to regulate business is the name as blocking the natural evolution of the species support the philosophy of?
social darwinism
Darwin proposes that all species of the natural world are in a constant state of evolution whereby natural selection plays a pivotal role in the survival of species Do you agree with this theory of yo?
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.
