WebHybridization may increase the invasiveness of introduced species, either by introducing genetic variation, heterosis, or by creating novel genotypes which perform better in a given environment. Gene flow between introduced and native species can also result in the loss of biodiversity through genetic pollution. WebTHE FORCES OF EVOLUTION. Today, we recognize that evolution takes place through a combination of mechanisms: mutation, genetic drift, gene flow, and natural selection. These mechanisms are called the “forces of evolution” and together they can account for all the genotypic variation observed in the world today.
