1·I can imagine that seed dispersal might be a factor.

我觉得种子传播可能是一个因素。

2·Plant species dependent solely on seeds for survival or dispersal are obviously more vulnerable to any decrease in plant fecundity that occurs.

显然，仅依靠种子生存或传播的植物物种更容易受到植物繁殖力下降的影响。

3·The structure of cycads male cones is quite consistent with the wind dispersal of pollen, clouds of which are released from some of the larger cones.

4·The nature of the geographic separation necessary to isolate populations depends entirely on the biology of the organism and its potential for dispersal.

地理上的隔离是隔离种群所必需的条件，且地理隔离的性质完全取决于生物体的生物学特性及其分散的可能性。

5·The most successful groups of land plants are those that evolved methods of fertilized sex cell dispersal that are independent of water and structures that protest developing embryos from drying out.

最成功的陆生植物群体是那些进化出了受精性细胞散布方法的群体，这些方法不依赖于水和防止发育中的胚胎干涸的结构。

6·Plants have different mechanisms of dispersal for their spores.

9·It was once assumed that improvements in telecommunications would lead to more dispersal in the population as people were no longer forced into cities.

10·What we see today is the product of evolutionary events, resulting from the dispersal of a few human populations out of Africa around 60,000 to 70,000 years ago.

我们今天看到的是进化事件的产物，是大约6万到7万年前少数人类从非洲迁徙而来的结果。
