What evidence do these similar structures provide in support of evolution?

Comparative DNA samples from chimpanzees and humans show very well the concept of evolutionary common ancestry. Aside from that, the differences in DNA among organisms, especially at certain loci, show how long two, or more, organisms shared common ancestry.

How do fossils provide evidence that evolution has taken place?
Fossils show evidence of evolution by showing a picture to the past and through some methods how DNA of one animal may be similar to that of a modern animal.
The approach to evolution that involves the study of similar structures that appear during the development of different organisms is known as the study of?
Comparative Embryology- This is the study of similar structures appearing during the embryonic development of related organisms.
What does your current evidence tell us about the evolution of prokaryotes and eukaryotes?
Prokaryotes are much simpler organisms than eukaryotes. It is thought that eukaryotes evolved from prokaryotes. In both cases the evolution process was lengthy and similar to the evolution of other organisms.
How does comparative anatomy support then idea that organisms share ancestors?
Comparative anatomy does not prove evolution itself, but is strong evidence because it shows that animals and species do change through periods of time; if evolution were not so, there would be no comparison possible since they would either be exactly the same or they would be different species.
How can a taxonomist might use embryological evidence in classifying an organism?
Related species have similar embryos.
What is the study that can provide evidence of evolution?
Fossils, patterns of early development, similar body structures, DNA, and protein structures.
What are examples of structural evidence of evolution?
Similar bone structures in species
Similarity of structure of the forelimb of a bird and a mammal is an example of what evidence?
Homologous structures - the forelimb structures are anatomically similar and were derived from a common ancestor; however, they have evolved completely different uses. This provides evidence for divergent evolution or adaptive radiation.
How fossil provide evidence that evolution has taken place?
Fossils show evidence of evolution by showing a picture to the past and through some methods how DNA of one animal may be similar to that of a modern animal.

What are similar structures that evolved independently called?
Similar structures that have evolved independently are called homologous structures. An example would be the wings of a bird and the wings of an insect.
Why are vestigial structures evidence of evolution?
Because of the morphological homologies they display with similar structures in other extant and extinct lifeforms, following, like virtually every other morphological or anatomical feature of life, the nested hierarchies of biology.
What evolution is called when unrelated organism live in similar environment?
And come up with similar solutions, both physiological and behavioral? Analogous structures arising from convergent evolution.
The structure of the forelimb of a bird is similar in structure to that of the forelimb of a mammal suggesting that both descended from a common ancestor What is this similarity an example of?
Homologous structures - the forelimb structures are anatomically similar and were derived from a common ancestor; however, they have evolved completely different uses. This provides evidence for divergent evolution or adaptive radiation.
How can embryonic development can be used as evidence for evolution?
Related species have similar embryos.
How do analogous structures support evolution?
Since the wings of insects and birds have different structures (or different designs) but perform similar functions, they are analogous organs. Now, since the analogous organs have different basic design, so they do not indicate a common ancestor for the organism. The analogous organs provide evidence for the evolution in another way. The presence of analogous organs indicates that even the organisms having organs with different structures can adapt to perform similar functions for their survival under hostile environmental conditions. Thus, the presence of analogous organs in different animals provide evidence for evolution by telling us that though they are not derived from common ancestors, they can still evolve to perform similar functions to survive, flourish and keep on evolving in the prevailing environment. The analogous organs actually provide a mechanism for evolution.
What evidences exist to support evolution?
Fossils, Similarities in early development, and similar body structures
