阅读下面短文,回答下面问题。
今天的生态圈是自然界漫长发展的产物,是自然史的积淀。整个生态圈中的格局也是自然进行自我调节的结果。生态圈的这种自我调节机制使生态总是处于一种动态平衡之中,总是达到一种有序状态。旧的有序状态破坏了,经过自我调节又达到一种新的有序平衡态。生态的这种自我调节机制来源于生物乃至生物DNA的自我调节机制。或者说是 DNA自我调节机制的发展或宏观形态。在这里,微观调节机制与宏观调节机制是全息的。倘若DNA没有自我调节机制,那么整个生态系统也就失去了生命活力,生态进化也就不可能了。可以说,DNA是一个生态微观全息元,它是整个生态史的缩影,它凝聚着整个生态圈中生态变化、演化的信息,它是宏观变化的微观反映。
DNA对生态信息的记录是以生物体为中介的。生境的变化必然引起个体行为的变化,个体行为的变化是对生境变化的适应。如果变化了的生境具有稳定性,那么生物的行为、特征等也就具有稳定性。生物在这种稳定性中形成起来的行为、特征等就会逐渐内化到 DNA中去,成为生物的本能。生物的多样性就是生境的多样性造成的,是生物适应生境的结果,是生境多样性在生物主体上的显化。这在岛屿生态系统中比较明显。由于岛上群落生境的单一性,就引起了生物群落和生态系统的简单化。这种简单化招致生态小生境数量的减少以及种类组成的贫乏。生态系统的简单化,也改变着竞争和捕食的因素,并给例如不会飞翔的鸟类的出现创造了条件。生境的变化又导致了对某物种的自然选择,使某些不适应这种变化的生物迅速消失,适应者迅速发展起来。可见,物种也是生境变化的结果。

下列理解不符合原文意思的一项是:

A.“DNA对生态信息的记录”和“生物的行为、特征等内化到DNA中去”不是一回事。

B.说DNA是生态微观全息元,意味着它具有整个生态圈中生态变化、演化的信息。

C.不会飞翔的鸟类的出现,从一个侧面说明生物的多样性是生境的多样性造成的。

D.生境的变化是导致物种变化的原因。

(C)

Everyone gathered around and Paddy read out loud, skowly, his tone growing sadder and sadder. The little  headline said: BOXER  RECEIVFS LIFF SENTENCE.

Every time it lookcd as if there might be happinegs for Fee . Frank took it away.  But Paddy's love for her was as deep and impossibile to wipe out as hers was for Fiank.

So he said.  " Well,  Fee,  we won't  go  But we must make sure he is taken care of.  How about if l write to Father Jones and ask him to look out for Frank?
