Indeed, it was on an expedition to the area that Alfred Russel Wallace came up with the idea of evolution by natural selection and, through a letter to Charles Darwin describing his hypothesis, panicked Darwin into publishing his own thoughts on the matter in "The Origin of Species".

实际上，这里曾是阿弗莱德？拉塞尔？华莱士依据物竞天择的进化论理念前来探险之地，他在一封写给达尔文的信中描述了自己的假设，迫使达尔文在出版的《物种起源》一书中加上了自己对该问题的看法。

O. Wilson calls it "the greatest scientific book of all time", it does no harm to remember that he hurried to publish "The Origin of Species" because he thought he was about to be scooped by his fellow naturalist Alfred Russel Wallace, who had independently come up with much the same idea of evolution through natural selection.

O。威尔森称其为"世上最伟大的科学著作"）同样伟大的是阿尔弗雷德·罗素·华莱士，他独立地提出了很多相同的通过自然选择而进化的思想。

There is an edited edition of his letters from his trip round the world on HMS Beagle（注2）, an effort to connect his life with that of Abraham Lincoln (who was born on the same day, February 12th 1809), an attempt (surely redundant for supporters and futile for opponents) to explain "Why Evolution is True", and even a collection of essays on Alfred Russel Wallace（注3）, who came up with the idea of natural selection at the same time as Darwin, and bounced him into publishing before he was really ready.

有一本书对达尔文乘坐贝格尔号环游世界期间所写信件加以修订，另一本费尽心思将他与同于1809年2月12日出生的亚伯拉罕。林肯牵扯在一起，还有试图解释"进化论为什么不可摇撼"（当然，这对支持者略显多余；对反对者则是徒劳无功），甚至有一本关于阿尔弗雷德。罗素。华莱士的随笔集也随之问世（华莱士和达尔文同时提出了自然选择的理论，正因读到华莱士的论文，达尔文的《物种起源》才未臻成熟就付诸出版）。

Darwin accepted blending inheritance, but Fleeming Jenkin calculated that as it mixed traits, natural selection could not accumulate useful traits.

达尔文承认混合遗传，但弗莱明·杰肯认为当性状是混合的情况下，自然选择不能积累有益性状。

They suggest both are the result of natural selection for enhanced brainpower.

The highest enzyme producer alkalophilic Bacillus sp SHY8-1 among the inductive strains was mutagenized several times, by adding enzyme production repression aegents into screen medium, combined with natural seperation and pressure selection, finally a CMCase-hyperproductive mutant SHY8-1-25 (partitally resistant to catabolite) was obtained, with the yield of CMCase raised to 13-16u/ml, maximally reached 18-20u/ml, while its parent strain 0.654u/ml.

对诱导型产酶菌-嗜碱芽孢杆菌SHY8-1进行了多次诱变改良，采用添加产酶阻遏剂的平板作为筛子，结合反复的自然分离、压力选择，最终成功地获得了高产变异株SHY8-1-25(已部分解除分解代谢阻遏)，产酶量由0.654u/ml提高到13-16u/ml，最高达到18-20u/ml，讨论了诱变机理策略，考察了碳、氮源等对产酶的影响，对培养基和摇瓶培养条件进行了优化。
