We meet with this admission in the writings of almost every experienced naturalist; or, as Milne Edwards has well expressed it, " Nature is prodigal in variety, but niggard in innovation" .

我们在几乎每一位有经验的博物学家的都会看到这种承认；或者，正如米尔恩·爱德华兹 (Milne Edwards) 所表达的那样， “大自然在多样性方面挥霍无度， 但在创新方面却吝啬” 。

The apple trees were in full bloom, and, as I stood gazing, the sun, which had all that day been niggard of its beams, burst forth gloriously.

苹果树盛开， 当我站在那里凝视时， 一整天都被吝啬了光芒的太阳， 灿烂地绽放了出来。

" Rats and ruins. It is a niggard's gift that costs the giver nothing. Your own man Yarwyck says it will be half a year before the castle can be made fit for habitation" .

" 一聚居的废墟，给得冠冕堂皇，实际毫无价值。你的手下亚赛尔亲口承认，至少得要半年，那里才能辟出空间来住人。"

We can, in short, see why nature is prodigal in variety, though niggard in innovation.

简而言之，我们可以看到为什么大自然在多样性方面挥霍无度， 但在创新方面却吝啬。
