Why do mutations increase the effectiveness of natural selection?
1) They increase the genetic heterogeneity of individuals in the population.
2) Each species and population is saturated with mutant genes that make up the reserve of hereditary variation.
3) Mutations supply elemental material that is subsequently exposed to natural selection.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
