WebJan 1, 2005 · In terms of microevolutionary theory, it may be of little consequence whether macroevolution results exclusively from the cumulative effects of intrapopulational changes in the frequencies of small-scale gene variants, or involves an essential input of nonstandard (indeed often nongenic) “mutational” mechanisms at key stages. WebThe five "forces" that can cause shifts in gene frequency (microevolution) are: Natural Selection : when some genes are more beneficial than others to survival and/or reproduction, those genes tend to …
