How are embryos used as evidence of evolution?
this is because they have a link with early ancestors of similar structure.
What happens during the embryonic period of pregnancy?
The embryonic period are the first eight weeks of development of the child, beginning with fertilization. During this period, the embryo undergoes an amazing transformation from a single cell to a recognizably human embryo. In the mid-twentieth century, George Streeter devised a commonly used embryo classification system by dividing the embryonic period into 23 stages. The embryonic period is followed by the fetal period, which encompasses the remainder of theprenatal development.
How can embryos be used to show evidence of evolution?
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 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.
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 can embryonic development can be used as evidence for evolution?
Related species have similar embryos.
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.
What is indirect evidence?
Indirect Evidence of Evolution - is looking for signs of the results of evolution. - is evidence that can be used to deduce what you are trying to understand.
The term used to refer to the last seven months of human development?
Fetal Development period. Whereas the first 8-9 weeks is embryonic development or embryogenesis.
What are subdiciplines used to understand human evolution?
Subdisciplines used to understand human evolution include paleoanthropology, genetics, archaeology, paleontology, and primatology. Each of these fields provides unique insights into the origins and development of humans through the study of fossil evidence, genetic analysis, ancient artifacts, and the behavior of closely-related species.
What is evolution and how does it works?
Evolution is the development of something, widely used to describe how the existence of everything came to be. http://en.wikipedia.org/wiki/Evolution
Beta-carotene is consumed with food such as carrots and is converted into vitamin that is used as a photopigment and regulates embryonic development?
Vitamin A
Why are vestigial proof of evolution?
Evidence, not proof. Scientists do not prove things. Your coccyx for one bit of evidence, This is the " stump " of a vestigial tail that is now used for another purpose in humans; to help with sitting. Sometimes this tail does grow out in child development. This is evidence of the concept of evolutionary common ancestry.

How is DNA evidence used in evolution?
All species have the same genetic code.
