He suggests that the seeds of some plants were buried and then eroded back to the surface in order for them to survive the flood. Furthermore, the absence of oxygen tends to greatly prolong the viability of seeds which are viable only for short periods of time under normal subaerial conditions. Had carbon dioxide percolated through some of the Flood-deposited sediments, it must have also imposed a narcotic effect on many seeds, including at least some that would not otherwise have survived prolonged burial in a viable condition. Yet when narcotized by carbon dioxide, the seeds can survive in a viable state for at least several weeks and, if present in sufficient numbers, a few individual seeds out of a great number of initially buried may have survived the Flood year. Since CO 2 is normally associated with volcanism and high thermal gradients, an explanation of where the CO 2 came from would seem to be in order.
None is given.
There are some serious drawbacks to the book. First, as noted in the disclaimer, Woodmorappe resorts to lots of name calling when he does not like an adversary's argument. All this name calling is a distraction from Woodmorappe's points. Several arguments are not self-consistent. Thus one is left assuming that earthworms are not on the ark.
