We have conducted studies of the deoxyribonucleic acid (DNA) of mitochondria (mtDNA), organelles within cells that have their own unique DNA. This DNA is usually inherited only from the mother, and so changes in it serve as a useful clock for timing speciation events. We have, for example, replaced the mitochondrial DNA of cow egg cells with those from rabbits, fertilized these eggs and allowed them to gestate. The calves are born with the mtDNA of lagomorphs, and they live just fine, which shows there is nothing intrinsic to rabbit mtDNA that will not work in cows.
We can construct a hierarchy of life very similar to the tree designed by Linnaeus using mitochondrial DNA. This tree demonstrates the interconnectedness--the shared ancestry of life. This is probably the key genetic evidence for evolution.
There are plenty of other good pieces of evidences. Endogenous retroviruses (ERVs) are snippets of DNA inserted into genes or introns which then may be passed from one generation to the next. There is no compelling reason for the same sequences of foreign DNA in similar organisms aside from that of common ancestry.
As for human beings, we have our own tell-tale genetic evidence. Our #2 chromosome is clearly the result of a fusion of two earlier primate chromosomes. The evidence for this is abundantly clear. In addition, we also have a non functioning gene, L-gulonolactone oxidase (GULO) for the syntehsis of ascorbic acid we share with our simian ancestors. Why should monkeys and men share this common defect aside from common ancestry?
What else can I help you with?
How can DNA show some evidence of evolution?
DNA can provide evidence of evolution through the presence of homologous genes, which are genes shared among different species that originated from a common ancestor. Additionally, the similarity of DNA sequences between related species can show how closely they are related evolutionarily. Mutations in DNA can also accumulate over time, leading to genetic variation that drives evolutionary change.
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.
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.
What are the four types of evidence that supports the theory of evolution?
The four types of evidence that support the theory of evolution are fossil records showing transitional forms, similarities in embryology and anatomy across species (homology), biogeography (distribution of species around the world), and genetic evidence such as DNA comparisons that show relationships between different species.
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.
What is the biochemical evidence that supports evolution?
DNA
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.
Why is DNA a useful piece of evidence in studying evolution?
DNA is a useful piece of evidence in studying evolution because it carries genetic information that can show how species are related and how they have changed over time. By comparing DNA sequences, scientists can track evolutionary relationships and understand how organisms have evolved and adapted to their environments.

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.
How is DNA evidence used in evolution?
All species have the same genetic code.
What are types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils
