I will frankly admit that this sort of recreation of soft tissue from
bones strikes me as dubious...how common is this practice and has it been
shown to give good results (examples from forensics perhaps)? If Mr.
Morton has similar doubts or the utility of this reasoning is unknown (if
not suspect) then he might give it a rating of 2 or 3. The tool use and
"naked lady" statuette may seem like stronger indications of spirituality
or some such. He might give that a 5 or 6. The geological suitability of
the Mediterranean for such a flood as he proposes might rate a 9 or 10 on
This might help some of us who aren't in a position to evaluate the data
to know what those who are in such a position think about the relative
relevance of particular points.
