Book Club

读书俱乐部

This month at the Book Club we'll be discussing evolution – or in other words, how the structure of living beings change over centuries. To help us, we'll be looking at The Selfish Gene by the British scientist Richard Dawkins. First published in 1976, The Selfish Gene created a great deal of debate, and it continues to influence biologists today.

本月，在读书俱乐部中我们将会一直讨论进化——或者换句话说，就是数世纪以来生物是如何演变的。为了帮助我们讨论，我们将会一直看由英国科学家理查德·道金斯所写的《自私的基因》这本书。《自私的基因》首次出版于1976年，造成了大量的辩论，至今它仍继续影响着生物学家们。

In The Selfish Gene, Dawkins states that genes are the building blocks for the development of life. He also argues that the aim of a gene is to increase its importance in the overall characteristics of a living being, and that this is what leads to changes in DNA over the years.

在《自私的基因》中，道金斯声称，基因是生命发展的构成部分。他还认为基因的目的是要增加它在生物的总体特征中的重要性，而这就是数年来导致DNA变化的原因。

Join us for an interesting discussion!

快来加入我们的趣味讨论吧！
