Work done a couple of years ago by Mark Pagel of Reading University, in England, suggests that about a fifth of evolutionary change happens jerkily at around the time new species form.

Since an individual's social environment affects its success in terms of survival and reproduction, you might expect such changes to influence the speed or direction of evolutionary change.
既然，个体的社会环境会影响到它的生存和繁殖能力，那么进化的速度或方向会受到这些变化的影响也许就在会预料之中了。
The formal definition of coevolution runs something like this: "Coevolution is reciprocal evolutionary change in interacting species," says John Thompson in Interaction and Coevolution.
约翰•汤普森（4）在《互相影响和共同进化》一书中对“共同进化”做了一个正式定义：“共同进化是互相影响的物种间交互的进化演变。”
Even well-educated people are often fuzzy regarding the mechanics that drive evolutionary change.
甚至是受过良好教育的人对驱动进化的机制也经常迷惑。
Sometimes it's easy to understand how an evolutionary change took place, but it's more difficult to understand why.
