NEET BIOLOGY

Detailed explanation-1: -Evolution is the change in inherited characteristics or traits in a population of organisms over many generations. The mechanism that best explains evolution is a phenomenon known as natural selection.

Detailed explanation-2: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

Detailed explanation-3: -Biological evolution is the change in inherited traits over successive generations in populations of organisms. Evolutionary modification of traits occurs when variation is introduced into a population by gene mutation or genetic recombination or is removed by natural selection or genetic drift.

Detailed explanation-4: -But these changes don’t persist. It takes a million generations or more to evolve lasting changes, the study found. Darwin was right: natural selection is beavering away all the time, and yet evolution itself plods along like a stick-in-the-mud.

Detailed explanation-5: -Evolution is change in the heritable characteristics of biological populations over successive generations.
