2·The evolution of North American horse, which was once presented as a classic textbook example of gradual evolution, is now providing equally compelling evidence for punctuated equilibrium.
北美马的进化，曾经被作为一个经典的渐进演化的教科书案例，现在为点断平衡说提供了同样令人信服的证据。
3·We are the products of evolution, and not just evolution that occurred billions of years ago.

4·The question about the rate of evolution must now be turned around: does evolution ever proceed gradually, or does it always occur in short bursts?
关于进化速度的问题现在必须解决：进化是逐步进行的，还是总在短时间内发生？
5·By analyzing the DNA, the genetic material of the proteins, the researchers could focus on the toxic genes and use them to trace the evolution of snake venom, and from this, the evolution of snakes.
通过对 DNA 及蛋白质中的基因物质进行分析，研究人员可以专注于有毒基因，并利用它们得到蛇毒的进化轨迹，这样也就知道了蛇的进化源。
6·Using phrases like "Darwinian selection" or "Darwinian evolution" implies there must be another kind of evolution at work, a process that can be described with another adjective.
使用“达尔文选择”或“达尔文进化论”这样的短语意味着工作中必须有另一种进化形式，一种可以用另一个形容词来描述的过程。
