I find the speed at which species would need to appear rather quick. However, I think that it is possible. I do understand why there is such fascination on how many animals could fit on the ark and the number of kinds. I do not think we can be 100% sure on these things.
So, you don't see any problem with species having to evolve at one or two a year? This would mean, essentially, that rats would have to give birth to a litter of mice spontaneously.
What mechanism could produce such rapid evolution and why don't we see it still today?
While we can't be 100% sure, we can get a good idea from the evidence. Creationism essentially says that evidence doesn't count if it doesn't fit the predetermined conclusion.
In other words, I think that every kind of animal was represented on the ark and saved from the flood. The reason we do not see every kind of animal that is in the fossil record living around us today is that they became extinct between the flood and now.
How do you define "kind"?
Where are all the bodies? There are a lot of extinct organism to account for.
Also, I would agree with the general consensus that AIG is not a good choice of source to be quoting from.
