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.

What mechanism did Charles Darwin believe caused evolution?
Natural Selection is what Darwin believed was the cause of evolution.
What best explains why mutations cannot 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.To say otherwise is incorrect.But mutations do cause evolution.

What can cause changes in DNA sequences?
mutations
Why dont all mutations cause cancer?
Mutations in the DNA can cause cancer, but it's not the only cause of cancer. Did you know you can get cancer if you are exposed to coals and tars too long?
Carcinogens are chemicals that cause?
Cancer or gene mutations.
What mechanism did Charles Darwin believe caused evolution?
Natural Selection is what Darwin believed was the cause of evolution.
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.
Why did ideas of Charles Darwin cause controversy?
Darwin's theory of evolution contradicts the literal interpretation of creation as taken from The Bible
Do mutations cause change in allele frequencies within a population?
Yes, they can. Mutation is one of the four main mechanisms of evolution.

mutations
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. 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.
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.
How do mutations cause genetic disorder?
it cause every cell
