Four evolutionary factors
WebFeb 24, 2012 · Summary There are four forces of evolution: mutation, gene flow, genetic drift, and natural selection. Mutations create new genetic variations in a gene pool. Gene … WebFour major forces are usually listed for changing gene frequencies in populations, namely migration, mutation, selection and random genetic drift. These forces constitute the mechanisms underlying the evolutionary process. 1. Migration: Migration occurs when a large influx of people moves into another population and interbreeds with the latter.

One tradeoff is between number of offspring produced and the amount of energy (both physical resources and parental care) put into each offspring. Timing of first reproduction is another tradeoff. toyota supra te koopWebEach of these four processes is a basic mechanism of evolutionary change and is illustrated with an example of gene frequency change in a beetle population with brown and green individuals.
