Is Genetic diversity is the raw material for evolution?

Answer 1

Mutations occur randomly, and every once in a blue moon, a mutation offers some benefit to a individual of a particular species in a particular place and allows that individual to have more offspring than its peers. If the mutation provides enough benefit to some individuals, they will have a tendency to survive and reproduce (as per the principle of natural selection).

Natural selection reduces variability by killing off less fit individuals. It is mutations that increase the variability and allow evolution (successful natural selection, not mass extinction, but controlled deaths) to occur. Without variability there is no evolution.

Answer 2

In the sense that genetic diversity is the raw material on which natural selection acts. The variant selected has progeny that may shift the allele frequency in a population of organisms over time, thus leading to evolution.

Answer 3

The raw material for evolution is the unit of heredity called the gene. A gene is part of the complex molecule called DNA.

Answer 4

genetic mutations in DNA that produce greater results for survival

Answer 5

Somewhat. Variation in organisms forms the material that natural selection works on and natural selection is the main driver of evolution, especially adaptive change.

Answer 6

The raw material for evolution is DNA.
