Genesis 7:2
Of every clean beast, you shall take seven pairs, male and
female; and of beast that not clean by twos, the male and his
female.
So God did cover all of the animals. Some animals weren't
inbreeders (not inbleeders) but some are, I suppose. Then again, as
of 2007, there are ~1.25 million fauna species on Earth, and they
are increasing every day. So just assuming that all of them are
unclean, Noah would already have to take 2.5
million specimens on board? o.O With enough food and clean water
for 150+ days...
That is one huge ship.
