您要查找的是不是：
- Mayr emphasized the importance of allopatric speciation, where geographically isolated sub-populations diverge so far that reproductive isolation occurs. 迈尔强调异域成种的重要性；在地理上孤立的亚群产生的分歧偏离太远，以致出现生殖隔离。
- 3) Geographic isolation may facilitate cryptic speciation of marine holoplankton.However,contribution of allopatric speciation is still questionable; 3)地理隔离有助于海洋终生浮游生物隐种的形成,但异域物种形成的作用仍值得商榷;
