Biology has catalogued many traits produced by point mutations (changes at precise positions in an organism's DNA)--bacterial resistance to antibiotics, for example.To say otherwise is incorrect.
But mutations do cause evolution. Biology has catalogued many traits produced by point mutations (changes at precise positions in an organism's DNA)--bacterial resistance to antibiotics, for example.

What else can I help you with?
Did Darwin believe that mutations are the main cause for evolution?
At the time that Darwin published his work the theory of genetic transfer of characteristics by Gregor Mendel had not been published. As a consequence genetic theory, mutations, recessive characteristics and allof those issues would be unknown.
How do lethal mutations and neutral mutations differ?
Lethal mutations cause such a radical change that the organism cannot live with it and dies. A neutral mutation is a simple change that does not affect the organism in any way, such as a new eye colour.
Do living things evolve because of mutations of their DNA?
Mutations usually cause things to evolve, depending on the gene which is mutated. Mutations are changes in the genetic material of an organism resulting in changes in the gene pool (if the mutated traits are passed on). If the mutated gene is a desirable/advantageous one, then the chances that it willbe passed on to future generations is increased. In this process, which occurs over a period of time, old genes may be lost in the gene pool, resulting in evolution.I don't see how it doesn't cause evolution.
Why can mutation affect evolution?
Mutations are random changes in an organism's DNA that can lead to new traits. These new traits can impact an organism's ability to survive and reproduce in its environment, influencing its chances of passing on these traits to future generations. Over time, accumulated mutations contribute to genetic diversity, which is essential for evolution by natural selection to occur.
Why dont all mutations cause cancer?
Not all mutations cause cancer because our cells have mechanisms in place to repair damaged DNA, preventing mutations from accumulating or causing harm. Additionally, mutations must occur in specific genes that regulate cell growth and division in order to lead to cancer. The body also has mechanisms to detect and eliminate cells with harmful mutations before they can develop into cancer.
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
Do mutations cause change in allele frequencies within a population?
Yes, they can. Mutation is one of the four main mechanisms of evolution.
Can chemicals found in cigarette smoke cause mutations to DNA?
Yes, chemicals in cigarette smoke, such as polycyclic aromatic hydrocarbons and formaldehyde, can interact with DNA and cause mutations. These mutations can lead to changes in the genetic information, which may increase the risk of cancer and other diseases.

Mutations are not able to cause things to evolve because?
Whoa. Mutations usually cause things to evolve, depending on the gene which is mutated. Mutations are changes in the genetic material of an organism resulting in changes in the gene pool (if the mutated traits are passed on). If the mutated gene is a desirable/advantageous one, then the chances that it willbe passed on to future generations is increased.

How do mutations relate to traits?
Mutations cause certain traits.
Can somatic mutations lead to evolution?
Only indirectly. For instance, the propensity of certain genes in somatic cells to mutate can itself be the result of a mutation in the germ plasm of the ancestor. Such mutations would alter the behaviour of the cell (they might cause a form of cancer, or they might cause the immune system to behave in new ways), and would therefore be selected for or against, causing the frequencies of alleles that regulate this propensity for mutation to shift in a certain direction over the generations. Other than that, mutations in somatic cells have little to no effect on evolution.
What types of external stimuli cause mutations?
While this question should be recategorized because external stimuli do not cause the mutations that result in hemophilia, there are many types of radiation that can cause gene mutations as well as chemical exposure. For example sun light is UV light radiation wich can cause mutations (for example the mutations that result in skin cancer).

What are some things that can cause those mutations that cause cancer?
Many herbicides and pesticides hit the nuclear material and cause mutations when used to protect crop plants. Apart from causing mutations these very chemicals are carcinogenic in nature and cause cancer.
