Answer:
How Mutations Can Lead to Human Evolution?
Explanation:
A mutation is the random change in the nucleotide sequence or in the DNA organization (genotype) of a living being, [1] that produces a variation in its characteristics and that is not necessarily transmitted to the offspring. It occurs spontaneously and suddenly or due to the action of mutagens. This change will be present in a small proportion of the population (variant) or the organism (mutation). The genetic unit capable of mutating is the gene, the unit of hereditary information that is part of DNA.
In multicellular beings, mutations can only be inherited when they affect reproductive cells. A consequence of mutations can be, for example, a genetic disease. However, although they may seem harmful in the short term, mutations are essential to our long-term existence. Without mutation there would be no change, and without change life could not evolve.

Answer:
When literacy rates goes up then crude birth rates will automatically be decline
Explanation:
Crude birth rate refers to the number of births /1000 in a population. It doesn’t count the age and sex in a population.
General fertility corresponds to number birth of a women age between 15- 49 in a year.
Factors Affecting fertility Rates: Healthcare,Education
Healthcare: Improvement in healthcare leads to drop infant mortality rate , knowledge of birth control measures and economic status have an impact on birth rates.
Education: Female literacy rate and knowledge of birth control and employment opportunities also decline crude birth rate.
