Julian Huxley presented a serious but popularising version of the theory in his 1942 book Evolution: The Modern Synthesis. In 1942, Julian Huxley's serious but popularising [70] [71] book Evolution: The Modern Synthesis [2] introduced a name for the synthesis and intentionally set out to promote a "synthetic point of view" on the evolutionary ...
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.
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 ...
Fourth, the modern evolutionary synthesis involved agreement about which forces contribute to evolution, but not about their relative importance. [36] Current research seeks to determine this. Evolutionary forces include natural selection, sexual selection, genetic drift, genetic draft, developmental constraints, mutation bias and biogeography.
Mainstream evolutionary psychology grew out of earlier movements which applied the principles of evolutionary biology to understand the mind and behavior such as sociobiology, ethology, and behavioral ecology, [5] differing from these earlier approaches by focusing on identifying psychological adaptations rather than adaptive behavior. [20]
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 ...
As a whole, these models argue the inadequacy of the modern evolutionary synthesis on the roles of genes and natural selection as the principal explanation of living structures. Developmental systems theory embraces a large range of positions that expand biological explanations of organismal development and hold modern evolutionary theory as a ...
