Recently polypod ferns have been demonstrated to undergo diversifications in the Cretaceous after the rise of angiosperms. To further test this proposal, an adaptive evolutionary analysis was performed on the rbeL gene sequences of Polypodiaceous ferns under models allowing w (nonsynonymous/synonymous rate ratio) to vary among sites.

为验证蕨类植物在白垩纪适应被子植物兴起而发生分化的观点，本研究以水龙骨科附生蕨类为对象，利用位点间可变ω（非同义替换率d和同义替换率d的比值）模型对其rbcL基因的适应性进化进行分析。

Species: sensitive fern; in some classifications included in Polypodiaceae.
