Despite repeated bouts of illness during the last twenty-two years of his life, Darwin's work continued. Having published ''On the Origin of Species'' as an [[abstract (summary)|abstract]] of his theory, he pressed on with experiments, research, and writing of his "big book". He covered [[human evolution|human descent]] from earlier animals including evolution of society and of mental abilities, as well as explaining decorative beauty in [[wildlife]] and diversifying into innovative plant studies.

尽管在他在生命的最后22年中反复发作疾病,但达尔文的工作一直在持续。在发表了《物种起源》作为其理论的摘要之后,他继续进行实验,研究和撰写了他的“全科书”。他介绍了人类起源于较早的动物,包括社会和智力的发展,以及解释野生动植物的装饰之美,并进行多样化的新型植物研究。

他对昆虫授粉的调查促使了1861年对野生兰花进行的全新研究,结果表明它们的花体具有适应性,以吸引特定的飞蛾进入每个物种并确保杂交。1862年,《'''<font color="#ff8000"> 兰花的传粉Fertilisation of Orchids </font>'''》首次详细展示了自然选择的力量,书中解释了复杂的生态关系,并提供可验证的预测。随着健康状况的下降,达尔文躺在房间里的病床上,房间里充满了许多创造性的实验,追踪攀援植物的运动轨迹。拜访者包括恩斯特·海克尔Ernst Haeckel,他是达尔文主义的热心拥护者,融合了拉马克主义和歌德的理想主义。华莱士也仍然支持他,尽管他越来越转向唯心论。

Darwin's book ''[[The Variation of Animals and Plants under Domestication]]'' (1868) was the first part of his planned "big book", and included his unsuccessful hypothesis of [[pangenesis]] attempting to explain [[heredity]]. It sold briskly at first, despite its size, and was translated into many languages. He wrote most of a second part, on natural selection, but it remained unpublished in his lifetime.<ref>{{Harvnb|Freeman|1977|p=[http://darwin-online.org.uk/content/frameset?viewtype=text&itemID=A1&pageseq=123 122]}}</ref>

达尔文的著作《动物和植物在家养下的变异The Variation of Animals and Plants under Domestication》(1868年)是他计划中的“全科书”的第一部分,包括他试图解释遗传,但是未能成功解释的假说。尽管“全科书”这一部分规模很大,但它一开始就卖得很快,并被翻译成多种语言。之后他写的第二部分则大部分是关于自然选择的,但是在接下来的日子里最终未能出版。
