WebDifference from macroevolution. Macroevolution is guided by sorting of interspecific variation ("species selection"), as opposed to sorting of intraspecific variation in microevolution. Species selection may occur as (a) effect-macroevolution, where organism-level traits (aggregate traits) affect speciation and extinction rates, and (b) strict-sense species … WebBiologyWise provides a brief description of the four basic modes of speciation, namely allopatric, parapatric, peripatric, and sympatric speciation. “Multiply, vary, let the strongest live and the weakest die.”. … WebTypes of Speciation: Speciation is of following types. 1. Allopatric Speciation (alios— other, patria— native land): In this type of species formation, a part of the population becomes geographically isolated from the main population.
