GEOLOGY

Detailed explanation-1: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

Detailed explanation-2: -In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.

Detailed explanation-3: -Charles Darwin understood that evolution was a slow and gradual process. By gradual, Darwin did not mean “perfectly smooth, ” but rather, “stepwise, ” with a species evolving and accumulating small variations over long periods of time until a new species was born.

Detailed explanation-4: -Evolution Is Change in the Inherited Traits of a Population through Successive Generations.

Detailed explanation-5: -The genetically inherited trait that increases the survival of that species would persist through the process of evolution by NATURAL SELECTION. The genetic trait that evolves from this process increases the probability that the species will survive in that particular environment is called an ADAPTATION.
