Atomic theory basically states that matter is made up of discrete units called atoms where atomic radii are measured in the angstrom level (10^-10 meters) the standard model of the atom is the electron cloud model. This knowledge has resulted in the development of a more complete understanding of genetic changes that is usually described as the synthetic theory of evolution.

The modern synthesis was the early 20th-century synthesis reconciling charles darwin's theory of evolution and gregor mendel's ideas on heredity in a joint mathematical framework julian huxley coined the term in his 1942 book, evolution: the modern synthesis.
The combination of darwin’s theory of evolution and mendel’s theory of heredity is known as the modern synthesis and includes four causes of evolution population genetics tries to answer questions about why and how changes in the gene pool occur. The modern synthesis established that over time, some researchers answered no evolutionist lynn margulis showed that a major organizational event in the history of life probably involved the merging of two or more lineages through symbiosis. Huxley coined the phrase, the ‘modern synthesis’ to refer to the acceptance by a vast majority of biologists in the mid-twentieth century of a ‘synthetic’ view of evolution. The modern evolutionary synthesis is about evolution it explained how the discoveries of gregor mendel fit with charles darwin 's theory of evolution by means of natural selection mendel found out how we inherit our genes. The modern synthesis (also called neo-darwinism) was the work of many people, combining experimental and theoretical approaches, including fisher, haldane, wright, dobzhansky, mayr, huxley, simpson, and williams.
The modern synthetic theory of evolution showed a number of changes as to how the evolution and the process of evolution are conceived the theory gave a new definition about the evolution as “the changes occurring in the allele frequencies within the populations, ” which emphasizes on the genetics of evolution.

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. What, then, was the importance of the “modern evolutionary synthesis” to evolutionary theory perhaps jbs haldane said it best: the permeation of biology by mathematics is only beginning, but unless the history of science is an inadequate guide, it will continue, and the investigations here summarized represent the beginning of a new.

The resolution was called the evolutionary synthesis or modern synthesis, and one of its architects was russian population geneticist theodosius dobzhansky, who lived from 1900 to 1975. I call this updated theory the “integral model” of biological evolution because it integrates darwin’s ideas with the modern synthesis with major breakthroughs in biology over the past 50 years. 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.
