av A Forsman · 2015 · Citerat av 16 — The question whether greater diversity in functionally important traits stabilizes populations under more complex ecological conditions in the

Stabilizing selection operates by means of the removal, or elimination, of individuals who deviate from the established norm. Therefore, under the influence of stabilizing selection, a population remains unchanged for a given characteristic, despite the continuous process of mutagenesis.

Stabilizing selection ensures the preservation of persistent and bradytelic forms, as well as the preservation during phylogeny of old characteristics that have not lost their adaptive significance. For example, the structure of the thyroid gland’s hormone —thyroxine—has remained unchanged throughout the evolution of vertebrate animals. 2019-09-20 · Azcolvin429 (Selection_Types_Chart.png) / GFDL. The most common of the types of natural selection is stabilizing selection. In stabilizing selection, the median phenotype is the one selected for during natural selection.
