How is evidence from DNA useful in understanding the evolution of species?
Wiki User
∙ 11y ago
DNA molecules contain the assembly instructions for every living creature. Scientists compare DNA from ancient and present creatures to identify genetic similarities among species. The genetic similarities among species is the main evidence of evolution theory.

What qualities make evidence useful?
Dna fibers
Is the biological species concept is useful only for extinct organisms?
No, biological species concept is NOT useful for extinct organisms at all, nor organisms that reproduce asexually; it is only useful for organisms that produce sexually.
Is it true that To be a useful index fossil a species must have been rare?
False.
Which genetic engineering branch is most useful for the goal of supplying evidence in court?
Genetic FingerPrinting
What is plant molecular biology?
Molecular biology is the study of how proteins and other molecules interact. Plant Molecular Biology studies this in plants. Each gene is a blueprint for a protein, and it is variation in genes that produces the differences between species, as well as inherited differences between individuals of the same species. So, by studying life at the molecular level we can gain new insights into nature of life. Plant molecular biology might include identifying and understanding useful proteins in one species that confer a trait such as disease or drought resistance, and introducing them into another species which you would like to have that trait. Alternatively, it might be useful for inventing a new weed killer that is specific to weed species, but does not kill the crop you are trying to protect.
How are hominid fossils useful in the study of the history of mankind?
Because they are evidence of evolution!
How is anatomy used as evidence for evolution?
Anatomy is a useful tool in gaining evidence for evolution. The most useful thing is to examine homologous structures, ie anatomical similarities between different species. The best example of this is the pentadactyl limb. It is found in humans, dolphins and bats. This shows that at some point in the past there must have been a common ancestor from which these 3 diverse groups of animals evolved.
Why is it useful for a criminal lawyer to have a basic understanding of the principles of forensic pathology?
Knowing how the evidence works means you can then use it to support or fight the accusations made.
What makes evolution a therory?
Evolution, the change in allele frequency over time in a population of organisms, is fact. The theory of evolution by natural selection explains much about the fact of evolution. That is what make a theory, explanation. Facts are useful, but uninteresting. Theories explain facts by gathering many convergent pieces of evidence and putting it into a logical and consistent whole.
How does variation lead to evolition?
Variation is caused by new genetic mutations in a population which lead to different traits in a population. Evolution selets the most useful of these mutation, eventually leading to prominence of new traits within a species or population, or even new species.
Why is the theory of evolution important to doctors?
AnswerIt explains how we got to be the way we are, logically and accurately. Understanding where the appendix came from is useful for understanding how it functions in the body today. The same is true for lots of body parts including systems like the immune system. Hope this helps!It is also important for doctors because of drug resistant bacterias and viruses which is a direct result of evolution through mutations and natural selection.

Is the Darwin theory of evolution true?
We don't use the word "true" to describe scientific theories. They either fit the facts or they do not. Darwin's theory of evolution fits most of the observed facts, and does so beautifully. A theory is useful if it makes successful predictions. Darwin's theory has absolutely zero to do with belief in God. The Catholic Church does not hate God, yet endorses the view that evolution has occurred in much the way Charles Darwin described. Is there a scientific theory that better explains the evidence from paleontology, geology, anatomy, and molecular biology? No. Therefore, we provisionally accept the theory of evolution as an accurate depiction of the origin of species. Again, this has nothing to do with whether or not God exists and/or loves you. Evolution is wrong. God is true.
