Henry Charlton Bastian was the most prominent leader of that faction of Darwinians, though Huxley was so successful in defining them out of the story that very few people today even realize that there WERE Darwinians who were serious, talented evolutionary scientists, yet also thought abiogenesis was necessary in evolution up to the present day.

巴斯蒂安。亨利查尔顿是那一派系达尔文主义者的最杰出领导者，虽然赫胥黎是如此成功将他们划出了这个故事，以至于今天几乎没有人还认识到曾经有这样一群达尔文主义者，他们是严肃的，富有天赋的进化论科学家，并且直至今日依然认为自然发生说在进化论中是必需的。

If a mother's stress adversely affects the development of her fetus then selectively aborting boys, rather than wasting time and resources on bringing them to term, would make evolutionary sense.

At present the mechanism of endangered species mostly confined to the morphology point of view, few physiological point of view of ecology, the lotus leaf fern Adiantum growth conditions of the study also stay in more qualitative analysis, there are few quantitative analysis of its optimum growth environment , The experimental use of morphological and physiological ecology of the idea and will use the components of the research methods, to be a long time to further explore their own independent development of plant taxonomy, morphology, physiology, ecology and other subjects the intrinsic link between , With a view to a new high on the survival of endangered species, adaptation and evolutionary mechanism.

目前对物种濒危机理的研究大都局限在形态学角度，很少有生理生态学角度的研究，对于荷叶铁线蕨生长条件的研究也多停留在定性分析上，很少有定量分析其最适生长环境，本实验采用形态学与生理生态学结合的思想，并将采用构件理论的研究方法，拟进一步探讨长期以来各自独立发展的植物分类学、形态学、生理学、生态学等学科之间的内在联系，以期能在一个新的高度上探讨濒危物种的生存、适应对策和进化机制。
