進化枝（Clade）是指生命進化樹上包括祖先分枝和所有子代分枝（branch）總和的一個群體分枝。比如說，圖中藍色和紅色區域可以稱為clade，而綠色區域不可以，因為他是一個不完整的群體，藍色群體也是其子代。
基本介紹
- 中文學名：進化枝
- 英文：clade
Aclade(fromAncientGreek:κλάδος,klados, "branch") ormonophylum(seemonophyletic) is a group consisting of an ancestor and all its descendants, a single "branch" on the "tree of life".The ancestor may be an individual, a population or even aspecies(extinctorextant). Many familiar groups,rodentsandinsectsfor example, are clades; others, likelizardsandmonkeys, are not (lizards excludes snakes, monkeys excludes apes and humans).
