WebRegions rich in endemism tend to have experienced major events that caused fragmentation of the ranges of many species. Such fragmentation events leading to geographic isolation include continental drift, mountain building, and sea level changes. Subsequent to their isolation, taxa may undergo evolutionary radiation in a given locality. WebSep 16, 2024 · Hint: Continental drift affects organisms by changing the current environment in all of these ways. Organisms may have to adapt, move, or go extinct. a. It causes climate change, which puts selective pressure on organisms. b. It causes changes in habitats, such as when large amounts of shallow marine habitat were lost in the formation …
Speciation And Continental Drift - Biology Resource
WebHow does continental drift affect evolution? As continents broke apart from Pangaea, species got separated by seas and oceans and speciation occurred. Individuals that were … WebVicariant Speciation. Vicariant speciation—also known as dumbbell speciation—occurs when a physical barrier, like a river or a valley, splits a population of a single species into two or more reproductively isolated groups.This process is illustrated in Figure 3 below. This diagram shows the process of vicariant speciation. A physical barrier splits a population … ctl in co
