Jun 27, 2019 · Darwin defined evolution as a process of “descent with modification.” He believed that some organisms within a species have trait variants that make them fitter and more likely to reproduce. Over time, inherited modified traits become dominant in the population, and a new species may emerge.
Apr 24, 2024 · Charles Darwin’s theory of evolution had three main components: that variation occurred randomly among members of a species; that an individual’s traits could be inherited by its progeny; and that the struggle for existence would allow only those with favorable traits to survive.

Darwin's explanation for this great unfolding of life through time—the theory of evolution by natural selection —transformed our understanding of the living world, much as the ideas of Galileo, Newton, and Einstein revolutionized our understanding of the physical universe.
Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection. This SparkNote will first take a look at Origin of the Species, and then more closely examine Darwin's theories .
