英文翻译句子
David held that many more individuals are produced than can find food and survive into adulthood

David 坚持认为,出生的个体远比能找到食物并长大至成年的个体多.
再问：还请分析一下才是。
再答： David 的观点与达尔文的理论相近。
达尔文认为适者生存。我的理解是，生物中普遍存在繁殖过剩的情况，同种生物间，个体存在差异甚至出现变异的情况。只有适合能外界环境的个体，才能生存下来，并将自己的基因传给后代。
比如，古代长颈鹿的脖子由于各种变异有长有短，长脖子的能吃到高处的树叶，而短脖子的吃不到。所以，在食物缺乏时，长脖子的能获得更多食物，而短脖子不能。所以后来只有长脖子的活了下来，并不断繁殖。
这就可以说明出生的个体未必都能活下来，只有适应环境的个体才能生存下去，长大到成年。所以说“出生的个体远比能找到食物并长大至成年的个体多”。
