Detailed explanation-1: -The sequence proposed by Darwin and Wallace for organic evolution is overproduction, variations, the constancy of population size, natural selection.
Detailed explanation-2: -Key points: The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Detailed explanation-3: -Ask most folks who came up with the theory of evolution, and they’ll tell you it was Charles Darwin. In fact, Alfred Russel Wallace, another British naturalist, was a co-discoverer of the theory-though Darwin has gotten most of the credit. Wallace died 100 years ago this year.
