Embryological development in animals displays the same set of nested hierarchies that is known from comparative morphology and genetics, and thus evidence for common descent.
Nota bene: this adherence to nested hierarchies is not to be confused with the 19th century hypothesis of ontogeny recapitulating phylogeny. Embryos do not go through evolutionary stages during their development, but they dodisplay atavistic developments that are consistent with phylogenies based on other sources.

How are embryos used as evidence of evolution?
this is because they have a link with early ancestors of similar structure.
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.
What are used as evidence for evolution?
Fossils. These show the incredible amount of time required to turn early life forms into stone. Studying the fossils, one can see the similarities and evolution of species over time. UNREST.
How is DNA used as evidence of evolution?
All living things have DNA -- both coding and non-coding DNA. The percentage of similarity between living things matches up with the preexisting theory of evolution.
How does embryology give evidence of evolution?
AnswerEmbryology does not provide any evidence for evolution. Ernst Haeckel's comparative embryo drawings have been known to be fraudulent for over 60 years although they are still used in some textbooks and by some ardent evolutionists. Embryos are different all through their development. Use of such alleged evidence is at best misleading and at worst is downright deceitful.Recent attempts to resurrect Haeckel's reputation only serve to show more details of his deceit. One example is how Haeckel deliberately left out the developing "heart pouch" from his drawings of the human embryo.Second answerComparative embryology shows that many different lifeforms go through similar stages of development, which points to common origins. You can read more about this online. Regarding the aforementioned fraud, Robert J. Richards, Professor of the History of Science and Medicine at the University of Chicago, states that the claims are "logically mischievous, historically naive, and founded on highly misleading Photography." For more, see his paper "Haeckel's embryos: fraud not proven."The Hox genes regulate body plans in embryological development, and are considered one of the primary pieces of evidence for common ancestry of species. Please also refer to the link from Christ's College on the Hox genes for that.
How can embryonic development can be used as evidence for evolution?
Related species have similar embryos.
How are embryos used as evidence of evolution?
this is because they have a link with early ancestors of similar structure.
Is fossil evidence used for the Theory of Evolution?
Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.

How could a study of these embryos help show the relationships among animals with backbones?
A study of the embryos could help show the relationships among animals with backbones. This will reveal the symmetry of the embryo which can be used for classification purposes.
How is DNA evidence used in evolution?
All species have the same genetic code.
What are the evidence used for hundred years ago to show the earth's is not flat?
what evidence could be used from four hundred years ago to show that the earth is not flat
Are people who believe in evolution ignorant?
If you mean, "are they ignorant for being in evolution," then no. The theory of evolution is a well-founded, heavily detailed theory with an enormous amount of evidence behind it. The theory of evolution is used to study disease. It's used to study agriculture. It's used to bring together all of the sciences pertaining to life.
What are four areas of study used as evidence of evolution?
Part 1: Evidence from the Fossil RecordPart 2: Evidence from Geographic Distribution of Living SpeciesPart 3: Evidence from Homologous Structures and Vestigial OrgansPart 4: Evidence from Embryologymore: What_are_the_four_pieces_of_evidence_for_evolution
How can evolution be seen over big amounts of time?
Through fossil and genetic evidence. Genetic evidence can be used to construct trees of relatedness; fossil evidence can be used to give us an idea of what remote ancestors looked like and when they lived.
What is indirect evidence?
Indirect evidence refers to information that requires some form of inference or interpretation to establish a connection to a particular fact or conclusion. It does not directly prove a point but rather provides clues or support for a theory or argument. Examples include circumstantial evidence or expert opinions.
