朗道的故事
在前苏联科协的一次会议上，
一个狗屁生物学家Lysenko作了一个后天特性的可遗传性的报告。
当报告结束后，朗道问他：你是认为，如果我们将一只母牛的耳朵给切了，
又将她的后代的耳朵都切了，那么根据你的理论，迟早会有没耳朵的小母牛出生啰？
Lysenko答道：对，就酱紫。
朗道又问：那么，你又怎么解释现在还有处女出生呢？
原文
It happened at the session of the Academy of Sciences of the
(former) USSR. The notorious agronomist Lysenko (founder of “creative
Darwinism”) gave a talk on the inheritance of acquired traits. When his
report was over, the famous physicist Landau asked: - So, you argue that if
we will cut off the ear of a cow, and the ear of its offspring, and so on,
sooner or later the earless cows will start to be born? - Yes, that’s
right. - Then, how you explain that the virgins still being born?
