cladogenetic

美[ˌklædədʒenɪsɪs] 英[klædəʊdʒenəsɪs]

n. [生]系枝发生；分枝进化

形容词：cladogenetic 副词：cladogenetically

First, there is speciation (species-splitting or cladogenesis), caused by geographical isolation or some other mechanism. 首先，因地理隔离或其它一些机制导致物种形成（物种分裂或系枝进化）。
Cook seems to have been the first to coin the term speciation for the splitting of lineages or cladogenesis, as opposed to anagenesis or phyletic evolution occurring within lineages. 这一术语与发生在世系内的“前进演化”或“种族的进化”这些提法相抵触。
