The fact that both micro- and macroevolution (including common descent) are supported by overwhelming evidence remains uncontroversial within the scientific community. However, there has been considerable debate over the past 80 years regarding causal and explanatory connection between microevolution and macroevolution. [1]
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 ...
Macroevolution is the outcome of long periods of microevolution. [136] Thus, the distinction between micro- and macroevolution is not a fundamental one—the difference is simply the time involved. [137] However, in macroevolution, the traits of the entire species may be important.
I raised the same objection to Maveric149, and he convinced me that it is indeed a biological concept. I did some more checking on my own and indeed, these are valid biological terms. The point of contention is whether there is an absolute or relative difference between micro- and 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
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]
Thrift Store Shopping and Sustainability. For Gen Z, thrifting is life. The last time shopping for used, vintage clothes and items was this hot was in the 1990’s. And think back to the 80s, when ...
Also, ecological inheritance can occur within a species that effects the entire biosphere, and thus ecological inheritance has significant implications for macroevolution. [ 14 ] [ 15 ] Ancestral species may modify environments through their niche construction that may have consequences for other species, sometimes millions of years later.
