The four main ideas of Darwin's evolutionary theory are variability in populations, overproduction of offspring, competition for resources and inheritance of traits. Variation provides advantages to some members of a population. The surviving individuals pass their traits to the next generation. 4.Evolution by natural selection is a process by which the characteristics of a population—not those of an individual—change over time. 5.The relative fitness of a trait or gene is defined as the expected reproductive success of an individual with that trait or gene, relative to other members of the population.
