The discussion of Noah's ark on Pharyngula brings to mind a topic that I have mused on before, but which people who know more biology than me might actually be able to take a stab at.
Just what would be the parasite load that all the people and animals on an ark would have to entertain? Some of the parasites that humans and our vertebrate and invertebrate kin are subject to are freaking nasty.
Would Noah's family have even been able to survive 7 months (or maybe 10 - the inspired word of god isn't sure on such things) with two of each kind of parasite (or was it seven) that couldn't be carried by their animals?. Or would they and the animals all be simultaneously blind, crippled, malnourished, crazy and dead?
