This land bridge collapsed, causing a cataclysmic flooding of the Mediterranean. Some implications of this scenario may seem unsettling. For example, so-called modern man did not appear on the scene until some 100,000 years ago, implying that Adam and his descendants, including Noah, were most likely one of the earlier hominids, such as homo habilis. However, this does not imply that Noah was some sort of subhuman. The physical differences between these hominids and later men do not necessarily imply that they were genetically different.
Dogs are all the same species.
But a fossilized Chihuahua and a fossilized Malamute might be mistaken for different species if these two fossils were found and dogs were not extant today. Furthermore, fossil differences cannot tell us whether modern man and earlier hominids differed spiritually. Reading Foundation, Fall and Flood can be tough slogging at times, because of the huge volume of detail presented. But the detail is well organized to support the central theme of the book, and the reader who persists will be rewarded with fresh insights into how Scripture and scientific knowledge can be integrated. If Morton's scenario is correct, the question of whether the earlier hominids were human is answered, at least in part.
