What Are Darwin's Four Main Ideas on Evolution? | Sciencing
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. See more
