According to the Encyclopedia Americana there are upwards of 1.700,000 species of animals. However, over 60 percent of these are insects, of the
24,000 amphibians,reptiles,birds and mammals, 10,000 are birds, 9,000 are reptiles and amphibians, many of which could have survived outside the ark,
and only 5,000 are mammals, including whales and porpoises, which would have also remained outside the ark. It is estimated that there a4re only about
290 species of land mammals larger than sheep and about 1,360 smaller than rats.
Excuse me a second while I laugh myself to death.
1) so, you think that most birds could stay aloft WITHOUT ANY FOOD for forty days and forty nights?
2) So you think that most reptiles could survive in the rising water, which near the sea would be brackish, inland would be not fresh but DISTILLED?
As much as a lot of reptiles can swim FOR A WHILE, they all have to breathe air and can you imagine a human, even an olympic swimmer, treading water
for forty days and forty nights without being able to drink?
(just a quick lesson for you: while humans can survive drinking slightly brackish water, the mammalian kidney is somewhat more efficient at removing
salt from the bloodstream than reptilian - including bird - kidneys are. Birds and the few species of reptile that can drink brackish/salty water have
specific adaptations which allow them to do so, AND ARE NOT COMMON TO THE REPTILIA. As for distilled water, it is bad enough keeping your skin in it
for a significant period of time, and, with a cheap microscope, a needle, a needle and a petri dish, you can see for yourself what distilled water
(collect fresh rainwater or buy it) does to cells. They swell up and pop after a fairly short time).
3) so far as I know, there is only a single species of amphibian that has the adaptations necessary to cope with long term survival in brackish water
- the crab-eating frog Rana cancrivora
, which I think copes with the osmotic gradient between its innards and its outards by having elevated
urea in the bloodstream. In all other species that I am aware of, keeping them in brackish water dehydrates them to death, keeping them in distilled
water inflates and ruptures their cells, as previously discussed. This is especially relevent in the case of amphibians, as most have highly permeable
4) the comment about insects remaining outside the ark is laughable. Most species, although not all, do have wings, but remaining aloft on these wings
is extremely energy demanding, and without regular food, most die. In some insects, the adult lifespan is a lot less than 40 days, so remaining aloft
before landing to breed is FAR out of the question. A lot - but not all - of the larvae of these are aquatic, but the same distilled/brackish water
concepts apply to them as to the reptiles and amphibians.
Fortunately there is something called a seed.
Dusty, I have an experiment for you. Find as many acorns as you can, and put a third of them in a large vat of distilled water for forty days, put
another third in a large vat of brackish water for forty days, and in a third vat - of similar size, to remove confounding variable - on autumn earth
for forty days.
When the forty days are up, make a note of what condition each one was kept in, and when the time comes for little acorns to start on their journey to
great oaks, make a note of what percentage of each, from the respective conditions, grow.
I'd be surprised if you get many from either of the wet conditions.
A seed contains an embryo, much as an egg does, and this embryo is alive, and thus vulnerable to osmotic gradients. Some seeds, certainly, can be
carried around on the ocean currents and survive, but such seeds tend to belong to mangroves, coconut palms and other shoreline plants which do not,
notably, make up the bulk of earth's vegetation.
I'm not particularly great at botany, but I do know enough to be able to add that a lot of the more primitive plants do not produce seeds - many of
the extant ferns being notable exampled. Instead, they rely on rainwater (in the relatively small volumes that it naturally occurs, which, by their
small volume, tend to have their solute content rather higher than an earth-covering of rainwater would) to allow sperm and ova to mix, giving way -
then and there, most of the time - to the next generation of ferns. Even if seeds COULD survive the sudden sweeping in of brackish and/or distilled
water, we'd still be without ferns.
The fresh water fish would have to stay in fresh water pockets, which would have been millions of gallons.
How about fish eggs?
Fish - phylogenetically including ourselves but here, for convenience sake, discussing only the pre-tetrapod sarcopterygians, the actinopterygii and
the chondroicthys, lack the amniotic membrane which gives the eggs of reptiles (including birds) and egg-laying mammals a certain - small - level of
water resistance. Most of these water resistant (think of it as the difference between water-resistant and water-proof watches. You can splash either,
but you can only submerge one) eggs would not survive being submerged for long, although some species are exceptional. Most fish eggs, lacking any
real barrier to solutes, are as sensitive, if not more so, as their parents to changes in the osmotic potential of their environment. That is to say,
if water gets saltier, they dehydrate, and if water gets less salty, they pop. The same concepts applied above to amphibians, then, apply to fish
eggs, and equally to fish.
Many bodies of fresh water would have received an unprecedented influx of not fresh, but distilled water, which is even more of an issue for fish than
it is for amphibians, because they breathe it. If you really want to see how this works, take a goldfish and put it in a large vat of distilled water
- separate to the acorns, otherwise it will be poisoned and die the wrong way - and come back to check on it 40 days later.
It will not be happy because it will be dead.
Oh, and a little aside - there are a number of species of fish that drown if you put them in water. Any water. Not to mention what happens when you
suddenly move salt-water invertebrates to brackish water which, as many marine invertebrates live in and around shallow water coral reefs, would
happen with that much rain. Just to let you know, it doesn't take more than a few minutes. So they wouldn't suffer for long.

EDIT: it was a YEAR? HOW could anyone think that it was even REMOTELY possible? Dusty, change all above experiments to a year. Although it probably
won't make much difference.
edit on 5/12/2010 by TheWill because: It was a year!!! Crikey these bible types are gullible!!!
EDIT: Dusty, Encyclopedia Americana lied to you. There's more than 10,000 amphibian and reptile species - I think it's close to 13,000 in total. How
old is your encyclopedia?
