He theorized that with the use of watercraft, people gradually colonized unglaciated refuges and areas along the continental shelf exposed by the lower sea level.
他的理论是，随着船只的使用，人们沿着因海平面下降而暴露的大陆架逐渐移居到未冻结成冰的区域。
Stephen Jay Gould, for example, argues that continental drift theory was rejected because it did not explain how continents could move through an apparently solid oceanic floor.
例如，斯蒂芬·杰伊·古尔德认为，大陆漂移理论之所以被否决，是因为它没有解释大陆是如何穿过明显很坚固的海底的。
By contrast, because sedimentation is much less continuous in continental regions, estimating the age of a continental bed from the known ages of beds above and below is more risky.
