The theory of evolution is a simple but elegant idea that species arose from a common ancestor and that new species continue to arise as a result of natural selection working on the biological diversity of existing populations.

The modern synthesis of the theory of evolution combines several different scientific disciplines and their overlapping findings the original theory of evolution was based mostly upon the work of naturalists the modern synthesis has the benefit of many years of research in genetics and .

In his review of evolution in 1953, j b s haldane expressed his thoughts about evolution with the following developmental analogy: “the current instar of the evolutionary theory may be defined by such books as those of huxley, simpson, dobzhansky, mayr, and stebbins [the founders of the modern synthesis].
Evolution is among the most substantiated concepts in science and is the unifying theory of biological science charles darwin co-originated, with alfred russel wallace, the theory of evolution by . Darwin's influence on modern thought (although the ignorant misapplication of evolutionary theory known as “social darwinism” often gets blamed for justifications of racism, adherence to . Has the modern theory of evolution overthrown darwinism it has not on the contrary, it has shown charles darwin to be incredibly insightful despite all the things he could not have known. One of the leading scientists in advancing modern evolutionary theory was sewall wright his work on inbreeding, mating systems and genetic drift made him, along with r a fisher and jbs haldane, the founders of population genetics theory. Their presupposition is that evolutionary theory is antithetical to a belief in the existence of a supreme being and to religion in general repeatedly in this trial, plaintiffs’ scientific experts testified that the theory of evolution represents good science, is overwhelmingly accepted by the scientific community, and that it in no way .
Modern evolutionary theory
The theory of evolution is one of the fundamental keystones of modern biological theory the diversity of the living world is staggering more than 2 million existing species of organisms have been named and described many more remain to be discovered—from 10 million to 30 million, according to some estimates. The theory of evolution by natural selection, first formulated in darwin's book on the origin of species in 1859, is the process by which organisms change over time as a result of changes in . Modern synthesis or modern evolutionary synthesis refers to several perspectives on evolutionary biology, namely: modern synthesis (20th century) , a historical movement in evolutionary biology between about 1918 and 1970.

Modern evolutionary theory (neo-darwinism) we have thus far talked about a lot of terminology, and we are in a position now to pull more pieces of the puzzle together into a coherent picture of what so-called “neo-darwinism” or the “neo-darwinian synthesis” really is. Evolutionary genetics is the broad field of studies that resulted from the integration of genetics and darwinian evolution, called the ‘modern synthesis’ (huxley 1942), achieved through the theoretical works of r a fisher, s wright, and j b s haldane and the conceptual works and .
