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.
