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 .
Modern synthesis or modern evolutionary synthesis refers to several perspectives on evolutionary biology, namely: Modern synthesis (20th century) , the term coined by Julian Huxley in 1942 to denote the synthesis between Mendelian genetics and selection theory.
The theory of evolution explains these homologous structures: all four animals shared a common ancestor, and each has undergone change over many generations. These changes in structure have produced forelimbs adapted for different tasks. [49] The bird and the bat wing are examples of convergent evolution.
An example of evolution as theory is the modern synthesis of Darwinian natural selection and Mendelian inheritance. As with any scientific theory, the modern synthesis is constantly debated, tested, and refined by scientists, but there is an overwhelming consensus in the scientific community that it remains the only robust model that accounts ...
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 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 ...
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
The modern synthesis a generation later, roughly between 1918 and 1932, broadly swept away all the alternatives to Darwinism, though some including forms of orthogenesis, [45] epigenetic mechanisms that resemble Lamarckian inheritance of acquired characteristics, [53] catastrophism, [58] structuralism, [69] and mutationism [78] have been ...
