常見(jiàn)例句用作形容詞 (adj.)It falls outside the scope of the formal taxonomic categories.它不屬于正規(guī)植物分類學(xué)的分類階元的范疇。For instance, all birds and reptiles are believed to have descended from a single common ancestor, so this taxonomic grouping is called monophyletic.例如,所有的鳥(niǎo)類和爬行動(dòng)物被認(rèn)為是從一個(gè)單一的共同祖先傳下來(lái)的,因此這個(gè)分類學(xué)的分組被稱為單系類群。 返回 taxonomical
