A mutation does not affect an organism trait for a reason. It is neutral which depends on the environment.
1. The mutation rates affect the evolution of the population by two factors. Firstly, every new mutation overcomes the effects of survival. When new mutations exist in one or two individuals, they are often lost from the population due to genetic drift, or change. For example, the mutation may never make it to a gamete and may get lost. Secondly, the selective value of the mutation can determine its affect of the population. If it's harmful then the selection would act to reduce its frequency and eventually remove it.
A frame-shift mutation has greater potential to affect the evolution of a population because it can alter the entire reading frame of a gene, leading to a non-functional protein. This can result in significant changes to an organism's phenotype, potentially affecting its survival and reproduction, and thereby influencing the population's evolution.

if there is too less population then the natural population will increase and there might be an end to the human population.
yes. yes it can.
It depends on the mutation. Some mutations have no effect on survival, some mutations are lethal, and some mutations make an individual better adapted to its environment, so it will be more fit than those without the mutation, and therefore produce more offspring with the same mutation, which could change the allele frequency of a population.

it changes it
Chromosomal mutation
A mutation is a change in the genetic code of one allele of your genetic code. ( rarely does mutation affect both alleles ) Most mutations are neutral, some are deleterious, but sometimes a mutation in the germ line can convey some slight advantage to progeny. An example of this is lactose tolerance in some peoples of the world.
"Neutral" isn't a molecular-level concept. A neutral mutation is one that doesn't affect the fitness of the organism; fitness is depending on the environment. For instance, a mutation that's neutral when nutrients are plentiful might become positive or negative if a particular nutrient becomes rare.
