The modern synthesis [a] was the early 20th-century synthesis of Charles Darwin's theory of evolution and Gregor Mendel's ideas on heredity into a joint mathematical framework. Julian Huxley coined the term in his 1942 book, Evolution: The Modern Synthesis .
Several major ideas about evolution came together in the population genetics of the early 20th century to form the modern synthesis of Huxley's title, including genetic variation, natural selection, and particulate inheritance. This ended the eclipse of Darwinism and supplanted a variety of non-Darwinian theories of evolution.
The modern evolutionary synthesis is the outcome of a merger of several different scientific fields to produce a more cohesive understanding of evolutionary theory. In the 1920s, Ronald Fisher , J.B.S. Haldane and Sewall Wright combined Darwin's theory of natural selection with statistical models of Mendelian genetics , founding the discipline ...
The idea of an extended evolutionary synthesis extends the 20th-century modern synthesis to include concepts and mechanisms such as multilevel selection theory, transgenerational epigenetic inheritance, niche construction and evolvability—though several different such syntheses have been proposed, with no agreement on what exactly would be ...
Modern synthesis (20th century), the term coined by Julian Huxley in 1942 to denote the synthesis between Mendelian genetics and selection theory. Neo-Darwinism , the term coined by George John Romanes in 1895 to refer to a revision of Charles Darwin's theory first formulated in 1859.
Evolution: The Modern Synthesis – book by Julian Huxley (grandson of Thomas Henry Huxley); one of the most important books of modern evolutionary synthesis, published in 1942; The Genetical Theory of Natural Selection – book by R.A. Fisher important in modern evolutionary synthesis, first published in 1930
Genetics and the Origin of Species provided the outline for a synthesis of genetics with evolution, and was enthusiastically received by both geneticists and naturalists. Dobzhansky laid out an advanced account of the evolutionary process in genetic terms, and he backed up his work with experimental evidence supporting the theoretical arguments.
George Gaylord Simpson (June 16, 1902 – October 6, 1984) was an American paleontologist.Simpson was perhaps the most influential paleontologist of the twentieth century, and a major participant in the modern synthesis, contributing Tempo and Mode in Evolution (1944), The Meaning of Evolution (1949) and The Major Features of Evolution (1953).
