How can mutations lead to human evolution?
lions [1.4K]

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.

The rapid decomposition of organic matter produces evidence which supports: the slow accumulation of coal deposits long ages of
mixas84 [53]

Answer:

rapid burial of vast amounts of vegetation

Explanation:

The organic matter is always decomposing, just that it depends on the conditions at what kind of a rate the decomposition will happen. If the climate is warmer and humid, then the decomposition is very quick. This results in a rapid burial of enormous amounts of vegetation. As the vegetation dies out, it piles up constantly, decomposes very quickly, and if there is something that can cover it, like mud for example, it will be buried in the ground. This is actually how the big deposits of coal have got the basis to form in the Carboniferous period.
