A study of distribution patterns of the diverse sexual forms among both monomorphous and polymorphous groups is expected to throw some light on the intermediate steps in the evolution of dioecism from hermaphroditism if one might assume that dioecy 作者: BAN 時間: 2025-3-23 03:08 作者: 保守黨 時間: 2025-3-23 09:29 作者: Blood-Vessels 時間: 2025-3-23 13:33 作者: 教育學(xué) 時間: 2025-3-23 17:07
