This … WebThere are a few basic ways in which microevolutionary change happens. Mutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population. Imagine that you observe an increase in the frequency of brown coloration genes and a decrease in the frequency of green coloration genes in a
WebHow does continental drift affect speciation? All of the listed responses are correct. Mutations in what class of genes have probably been responsible for many of the changes leading to the great diversity of life existing today? … WebGenetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations. Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100\% 100% frequency, of other alleles.
WebGlossary. Continental drift. The movement of continents as a result of plate tectonic processes. This was especially important for Southern Hemisphere continents. … WebAt the most basic level, mass extinctions reduce diversity by killing off specific lineages, and with them, any descendent species they might have given rise to. In this way, mass extinction prunes whole branches off the tree of life. But mass extinction can also play a creative role in evolution, stimulating the growth of other branches.
