Woody plants represent the ancestral growth form in angiosperms with herbs evolving repeatedly from them. While there are a number of hypotheses about drivers of the evolution of the herbaceous habit, the ability to avoid frost damage in winter by discarding their aboveground biomass has often been invoked as the main force in their evolution. We propose instead that any unpredictable disturbance might have been much more important than the seasonal frost, as herbs easily survive repeated disturbance.

草药的进化:难题的关键可能是宽容而不是回避

木本植物代表了被子植物的祖先生长形式,草本植物从它们中反复进化。虽然有许多关于草本习性进化的驱动因素的假设,但通过丢弃其地上生物量来避免冬季霜冻损害的能力经常被认为是其进化的主要力量。相反,我们建议任何不可预测的干扰可能比季节性霜冻重要得多,因为草药很容易在反复干扰中存活下来。
