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?
Charles Darwin proposed that natural selection was the mechanism responsible for evolution. This idea suggests that organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations, leading to gradual changes in populations over time.
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 is the cause and effect of Darwin's theory?
The cause of Darwin's theory of evolution was his observations of natural variation and adaptation in species during his travels, particularly in the Galapagos Islands. The effect of his theory was a paradigm shift in biology, leading to a better understanding of how species change over time through the process of natural selection.
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 did ideas of Charles Darwin cause controversy?
Darwin's theory of evolution contradicts the literal interpretation of creation as taken from The Bible
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 Mutations cause infections?
Mutations themselves do not cause infections; rather, they can occur in pathogens like bacteria and viruses, potentially affecting their ability to infect hosts. For example, mutations may enhance a virus's transmissibility or resistance to treatments, leading to more severe outbreaks. In this way, while mutations are a factor in the evolution of infectious agents, the actual infections are caused by the pathogens themselves, not the mutations directly.

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 is the correct statement for mutations?
Mutations are changes in the DNA sequence of an organism's genome, which can occur spontaneously or be induced by environmental factors. They can be classified as beneficial, neutral, or harmful, depending on their effects on the organism's fitness. While some mutations can lead to new traits that contribute to evolution, others may cause genetic disorders or diseases. Overall, mutations are a crucial source of genetic diversity in populations.

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).
