環境淘汰
表示
環境淘汰は、生物に作用する進化のメカニズムであり、性淘汰を含まないため、無性淘汰とも呼ばれる[1] [2] 。
選択的圧力
[編集]すべての生物は、環境が選択圧を及ぼす遺伝子プールの保管場所であり、この圧力はふるいのように機能し、環境により適した遺伝子プールを保管する生物はより多く繁殖するが、不適切なプールを持つ生物はより少なく繁殖し、個体群の異なる繁殖を引き起こす。それはより多数の繁殖を促進する環境であり、一部の個体の繁殖数の拡大と他の個体の繁殖数の収縮を促進する。
環境淘汰は、配偶者の選択がほとんどまたはまったくない場合、交配に関係なく集団のすべての形質が等しく繁殖する場合、および種が雌雄同体または無性生殖である場合に最大に機能する。
