Evolution is the change in allele frequency (genotype) over time in a population of organisms resulting in alterations of the phenotype. Change over time gives rise to the diversity of species.

The theory of evolution by natural selection is the nonrandom survival and reproductive success of randomly varying organisms. This is the main adaptive driver of evolution and can lead to speciation. All organisms are variations and the environment, the natural selector, preferentially chooses those with beneficial traits to be reproductively successful in the immediate environment at a greater rate than their fellow population members. As their descendents possess these traits, the alleles shift in the population gene pool and evolution occurs. Gene flow and genetic drift also cause evolution, especially in small populations, but they are not adaptive drivers.
Basically, theory of evolution is the theory that explains the diversity of life. Many believe the father of evolution was Comte de Buffon, a French naturalist. However, he was unable to come up with a reasonable mechanism that drives evolution. Charles Darwin later came up with natural selection as the mechanism that drives evolution and wrote about it in his book On the Origin of Species.

The theory of evolution proposes that species change over time through a process of natural selection, where organisms that are better adapted to their environment are more likely to survive and reproduce. Over long periods, these small changes can accumulate and lead to the formation of new species.
