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. Darwinism. Charles Darwin in 1868. Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809-1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.Overproduction. 3. Adaptation. 4. Descent with Modification. Why must there be variation in the population in order for natural selection to occur? Because if there is no variation, there is no survival of the fittest. If all organisms are the same, it makes no difference which ones are killed, the gene pool stays the same. If there is variance ...It helps in accumulating and preserving beneficial mutations that increase an organisms chance of survival. Darwin's theory of natural selection states that nature selects organisms that have features favorable for their survival, while eliminating inferior species. Natural selection is a key to the origin of new species from the existing ones. This competition follows from the conditions of limited resources and excess fecundity. Darwin referred to this ecological competition as the “struggle for.Evolution by natural selection occurs when certain genotypes produce more offspring than other genotypes in response to the environment.
