微生物学家总是花大量的时间对着显微镜，而我虽然没有真正意义上地追赶过救护车，但我通过为那些在救护车中呆过的人辩护来谋生。
Microbiologists spend some time with microscopes, and while I've never literally chased an ambulance, I make my living representing people who have spent time inside ambulances.
到目前为止，古生物学家认为恢复需要几千万年的时间——原因要么是由于大灭绝的深重影响，要么是由于火山爆发导致地球变成有毒的荒漠。
Until now, paleontologists have thought the recovery took tens of millions of years-a reflection either of the profundity of the Great Dying or of the toxic desert planet that the eruptions created.

这意味着先不考虑其他因素，若生物学家仅凭遗传变化具有规律性这一假设推算两个世系分化的时间，那么这种推算出来的时间可能就已经错了。
This means, among other things, that when biologists have calculated how long ago two lineages diverged by assuming change is regular, they may have their dates wrong.
曾经有段时间，生物学家或多或少滥用了一种证据，即这些生物通过杀死体弱者来保持种群的健康，或者说它们仅仅捕食没有价值的物种。
Time was when biologists somewhat over worded the evidence that these creatures preserve the health of game by killing the physically weak, or that they prey only on "worthless" species.
