The following appeared as part of an article in a business magazine.
"A recent study rating 300 male and female Mentian advertising executives according to the average number of hours they sleep per night showed an association between the amount of sleep the executives need and the success of their firms. Of the advertising firms studied, those whose executives reported needing no more than 6 hours of sleep per night had higher profit margins and faster growth. These results suggest that if a business wants to prosper, it should hire only people who need less than 6 hours of sleep per night."

提出旧理论:在 1940 年左右,大家都认为鞭毛(flagella)的功能是细菌用来辅助运动,摆动前进的,因为会动的细菌有其构造,且不会动的细菌没有,因此推论此构造是有关的。
旧理论的缺失: Pijper 认为这个理论不可取,当时对鞭毛研究提出了质疑。他认为因为鞭毛是一种多糖,没有证据能指明鞭毛可以移动细菌。当然,他还指出,就算使用当时发明的各种最先进的仪器, 比如电子显微镜(electronic microscope)也无法保证能观察到会动的细菌有此构造,因此这种说法是有问题的(有题)。而且,对活体细菌的观察是必须的。有可能是因为细菌自己游动然后导致尾部形成了一个延长体。并且这个关系到细菌分类的依据。同时他还认为用显微镜观察不如直接观察活的细菌更有价值。
结论:文章最后指出,后来的研究说明了鞭毛的确是可以作为细菌移动的 motor,但是作者说新的证据不是很充分,仍然没有一种说法能证实其为真确(暗示 Pijper 可能是对的)。Pijper 和别人的研究告诉了我们,因为他们从不一样的观察角度出发,得到了不同的结论。(有题)。
问题: Pijper 的观点的基于什么得出的?
