Rabbit
Reproduction Model

A single female rabbit can have 114 babies per litter,
but we'll be conservative and say that the average litter
size is six.
We'll also make the assumption (remember, this is just
a hypothetical thing) that only *half* of those are
females, and we will calculate the potential fecundity
of our bunny only from these hypothetical three females
per litter. (This is probably a conservative estimate.)
If our "starter bunny" begins reproducing
at age of six months (not unreasonable by any stretch),
and has babies for seven years (...which she probably
won't, if she's having that many babies. She'll probably
burn out after 23 years. But that's another story),
then she'll have, over the course of the first year:
1 mother rabbit x 3 female babies x 12 months = 36 female
babies (plus your original mama makes 37)
(I'm going to make an assumption here, and add the
new babies to the reproductive group at the beginning
of Year Two, at which point they'll be an average of
six months old. But this is less than perfect.)
Ifstarting at the beginning of Year Two each of
*those* female babies produced an average of 3 female
offspring per month then by the end of the second year
you'd have:
End of Year Two:
37 mother rabbits x 3 female babies x 12 months = 1332
female babies
(+ 37)
End of Year Three:
1332 mother rabbits x 3 female babies x 12 months =
47,952 female babies
(+ 1332)
End of Year Four:
49,284 x 3 x 12 months = 1,774,224 female babies
(+ 49,284)
End of Year Five:
1,823,508 x 3 x 12 months = 65,646,288 female babies
(+ 1,823,508)
End of Year Six:
67,469,796 x 3 x 12 months = 2,428,912,656 female babies
(+ 67,469,796)
End of Year Seven:
2,496,382,452 x 3 x 12 months = 89,869,768,272 female
rabbits!
(And we're not even counting the males!)
