Macroevolution comprises the evolutionary processes and patterns which occur at and above the species level. [ 1 ] [ 2 ] [ 3 ] In contrast, microevolution is evolution occurring within the population(s) of a single species.
Yuri Aleksandrovich Filipchenko, sometimes Philipchenko (Russian: Юрий Александрович Филипченко; 1882 — 1930) was a Russian entomologist who coined the terms microevolution and macroevolution, as well as the mentor of geneticist Theodosius Dobzhansky. [1]
As with Haldane and Fisher, Dobzhansky's "evolutionary genetics" [59] was a genuine science, now unifying cell biology, genetics, and both micro and macroevolution. [44] His work emphasized that real-world populations had far more genetic variability than the early population geneticists had assumed in their models and that genetically distinct ...
Macroevolution is guided by sorting of interspecific variation ("species selection" [2]), as opposed to sorting of intraspecific variation in microevolution. [3] Species selection may occur as (a) effect-macroevolution, where organism-level traits (aggregate traits) affect speciation and extinction rates, and (b) strict-sense species selection, where species-level traits (e.g. geographical ...
Controversially, Goldschmidt advanced a model of macroevolution through macromutations popularly known as the "Hopeful Monster" hypothesis. [ 3 ] Goldschmidt also described the nervous system of the nematode , a piece of work that influenced Sydney Brenner to study the "wiring diagram" of Caenorhabditis elegans , [ 4 ] winning Brenner and his ...
Simpson argued that the microevolution of population genetics was sufficient in itself to explain the patterns of macroevolution observed by paleontology. Simpson also highlighted the distinction between tempo and mode.
Lauren Sallan is an American academic who is the head of the Macroevolution Unit at the Okinawa Institute of Science and Technology and was previously the Martin Meyerson Assistant Professor in Interdisciplinary Studies at the University of Pennsylvania. She is a paleobiologist who uses big data analytics to study macroevolution.
Macroevolution – Evolution on a scale at or above the level of species Speciation – Evolutionary process by which populations evolve to become distinct species Natural speciation Allopatric speciation – Speciation that occurs between geographically isolated populations
