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.
