Think of it this way. We can use DNA to determine the relationships among a family (fathers, mothers, uncles, aunts, etc). This works because DNA holds clues to the ancestors of the organism it is in. So we can use DNA to determine how long ago two different species, or even families, etc had the same ancestor. So it's just like a regular DNA test, but scientists look at the relationship between species, not just individuals.
DNA is used as evidence for evolution because it can provide information about the genetic relationships between species. By comparing the DNA sequences of different organisms, scientists can determine similarities and differences, which can help to establish evolutionary relationships. This molecular evidence supports the theory of common ancestry and allows researchers to trace the evolution of species over time.
DNA is a long strand of nucleotides which form the genes that make up chromosomes. Scientists compare DNA from living organisms to identify similarities among species. The best explanation for many of the similarities we find is evolutionary common ancestry.
For example, the L-gulonolactone oxidase (GULO) gene is broken in both humans and old world primates. Evolution explains why the break is similar between us and all other platyrhinne, whereas in almost all other mammals the gene works just fine. The gene broke in some early primate ancestor, and because our diet has long been rich in ascorbic acid, this defect was never selected against, but instead became inherited among all descendant species.
All species use the same genetic code - A, T, C and G, the four bases used as ´letters´ in the genetic ´book´. This couldn´t have come to be independently, there was a single ancestor who passed the code on to all of us alive today through our ancestors tracing back to the first one.
Also DNA mutates over time, changing its code so it can code for different things in the plan of an organism. It does so slightly, so all species that ever existed slowly morphed into eachother. In the grand sweep of it, fish morphed into amphibians, amphibians into reptiles and so on. This didn´t happen between individuals - a fish didn´t give birth to an amphibian. It happened very slowly, and all thanks to the slow, slight mutation of DNA over time.

Why is information stored in DNA evidence for a creator and against evolution?
DNA evidence is not specifically stored as evidence for a creator or against evolution. However, some people may argue that the complex information encoded in DNA suggests an intelligent designer, while others view it as a product of natural selection and evolution. Ultimately, interpretations of DNA evidence depend on one's worldview and understanding of science and religion.
How is DNA used as evidence of evolution?
DNA can be used as evidence of evolution by comparing the genetic sequences of different species. Similarities in DNA sequences suggest a common evolutionary ancestor, while differences can indicate how species have evolved and adapted over time. By analyzing mutations and genetic variations, scientists can infer evolutionary relationships between species.
What A scientist makes the argument that she has found DNA evidence that shows that evolution does not exist. What would her evidence have to show for her to be correct?
For a scientist to argue that evolution does not exist based on DNA evidence, her findings would need to demonstrate that genetic mutations do not occur, that species do not share common ancestry, and that there is no evidence of natural selection influencing genetic variation over time. This would contradict the vast body of scientific evidence supporting the theory of evolution.
What are two types of evidence that suggest the evolution has occurred?
Fossil evidence, such as transitional forms showing intermediate characteristics between species, and genetic evidence, like similarities in DNA sequences among related species, both support the occurrence of evolution.
The study of can provide evidence of evolution?
The study of: (i) Cladistics: regional biodiversity, race circles, and geographical isolation; (ii) Genetics: DNA, chromosomes, viral insertions, common mutations; and (iii) Paleontology: fossils. These are some of the types of evidence for evolution.
How is DNA evidence used in evolution?
All species have the same genetic code.
What is the biochemical evidence that supports evolution?
DNA

Why is DNA the weakest evidence of evolution?
Actually, it is the strongest evidence for evolution. Without one fossil we would know from the DNA evidence that evolution has occurred and is occurring. It is in the DNA of organisms that we see the strongest evidence for common ancestry. The products of those genes are sometimes highly conserved down the ages. Ribosomes, the workbenches on which proteins are made, differ hardly at at between you and pets.

Where we apes?
The theory says we may have been because of evolution evidence and close DNA
How do they use DNA evidence today?
DNA evidence is used in criminal investigations to link suspects to crime scenes, identify victims, and exonerate innocent individuals. It is also used in paternity testing, identifying bodies in mass disasters, and studying genetic inheritance and evolution. DNA evidence is a powerful tool due to its accuracy and unique nature.

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.
