About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
