值得一看，尤其是博文后的评论。一些博友认为书名被译歪了，我一开始也认为书名不该这么译。

The title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.

Do you think it menas

(a) "On the Origin of Species by Means of Natural Selection, or (by Means of) the Preservation of Favoured Races in the Struggle for Life,"

or

(b) "On the Origin of Species by Means of Natural Selection, or (on) the Preservation of Favoured Races in the Struggle for Life"?
