求翻译：但是对有些物种，有些动物，那就是了不得的大事。有些动物是靠磁场导向的，靠磁场的方向，去寻找适合于它生长的地方。如果地磁倒了，它不能适应这种情况，这个时候，地磁场就引导它引导它到一个错误的地方去，这种生物，就容易灭绝，当然生物它可以适应外界环境的变化，地磁倒转过程，有几千年呢，如果在这几千年的过程中，它逐渐改变它的遗传基因啊，也可以适应新的环境。是什么意思？

But for some species, some animals made it and no big deal. Some animals rely on magnetic field orientation, depend on the direction of the magnetic field, to find the place suitable for its growth. Geomagnetic down, it can not adapt to this situation, this time, the geomagnetic field to guide it to

But for some species, some of the animals, and that is not a significant issue. Some of the animals that rely on magnetic field guide and the magnetic field direction, looking to go for it. If you magnetic down, it may not be able to adapt to this situation, this time, the magnetic field to guide it

But for some species, some animals, that's really great events. Some animals are oriented by magnetic field, the direction of the magnetic field, where to find suitable for its growth. If geomagnetic pour has, it cannot adaptation this situation, this when, to magnetic field on boot it boot it to a
