disruptive selection
A technical term in evolutionary biology referring to natural selection that favors extreme trait values over intermediate ones, potentially leading to speciation.
分断選択は、集団内の極端な形質を好む自然選択の一形態である。
Disruptive selection is a form of natural selection that favors extreme traits within a population.
自然選択 (natural selection) is the broader process; 分断選択 is a specific type of natural selection.
安定化選択 (stabilizing selection) favors intermediate traits, opposite to 分断選択.
方向性選択 (directional selection) shifts the population mean toward one extreme, while 分断選択 favors both extremes.
Compound of 分断 (division, splitting) and 選択 (selection), likely a calque of the English term 'disruptive selection'.
