High gene flow via sporedispersal in an earlier period when C. thalictroides was widely distributed in China is a plausible reason for the low genetic differentiation among populations.
孢子扩散引起的高的基因流可能是导致水蕨种群间低的遗传变异的主要原因。

But the first comparative analysis of fungal spore form and reproductive dispersal shows that shapes are no evolutionary accident.
