IAC's Global Flood Model assumes that 10 millions species "evolved" from 500 "kinds" of animals within a few hundred years. Here is why that is absurd (beyond obvious reasons):
Animals on the Ark
The young-earth model assumes Noah took pairs of the originally created "kinds" on the ark-virtually everything but insects and sea creatures.22 However, the Genesis flood account uses two different Hebrew words, nephesh and basar, to describe the animals taken aboard the ark. The word nephesh refers to "soulish" creatures that can relate to humans. The word basar refers to certain birds and mammals that interact with humans.23 Thus, the ark did not contain representatives of all the originally created "kinds." It only contained certain species of birds and mammals that lived within the reach of the Flood's devastation and were important to Noah's short-term survival.
The young-earth model also assumes the animals on the ark were unique-they possessed special genetic coding that allowed them to quickly adapt to the post-Flood environment and produce new species. However, nowhere does Bible state the animals on the ark were different or endowed with special qualities. Nor is there a single example from field research that supports this claim. If modern species descended from common ancestors on the ark, we would expect to find evidence of intermediate forms. We would also expect to see thousands of new species arising today. However, nothing we observe suggests today's species descended from common ancestors on the ark.24
In fact, rapid post-Flood extinctions seem to argue against the position the ark animals were endowed with special qualities. Young-earth creationists maintain God programmed the animals so they could survive and repopulate the earth. Yet, according to their model, a significant number of animals became extinct shortly after the Flood. For example, they contend Noah took dinosaurs on the ark but they were not able to survive the harsh post-Flood conditions and went extinct.25 If God endowed the ark animals with special qualities so they would survive, why did so many species go extinct? And, if only certain animals were endow these special qualities, why did God have Noah take the other animals aboard the ark?
Rapid Speciation (LOL)
The young-earth model assumes the animals on the ark were able to produce new species in a few hundred years. We know this is the maximum timeframe because historical records indicate some of the subtypes were in existence by then. However, animals, especially advanced animals, simply do not and cannot change at such rapid rates. If speciation really does operate this fast, why does any line exist at all that is stable enough and distinct enough to be called a species? Why is not the world filled with intermediate forms of every conceivable kind? Why have some species not changed from their ancestors in the fossil record?46 And why do we not witness thousands of animals species developing from others today?47
Young-earth creationists say no reputable creationist denies the fact of speciation.48 They also say examples of rapid adaptation-even to the extent of producing new species-abound.49 As evidence, they point to populations of mosquitoes, salmon and other creatures that no longer interbreed with their main populations.50,51 However, these are examples of reproductive isolation-as subpopulations get isolated they often won't interbreed with the main population due to behavioral reasons. For example, fish living in the same lake can acquire different food choices, which leads to different sizes and different mating preferences. For the young-earth model to be true, these processes need to able to produce macro changes and new organisms.
Ironically, many evolutionists now question whether descent through modification (natural selection working on random genetic variations or mutations) can produce the amount of change required to account for the diverse body plans and organs animals exhibit. Studies indicate few populations have the capacity to survive even normal environmental fluctuations.52 They also indicate small, isolated populations are not an advantage but a disadvantage because they give rise to serious genetic defects.53 Thus, the young-earth contention that genetic shuffling is capable of producing limitless biological change is more an article of faith than fact.54 Like punctuated equilibrium, the young-earth model would suffer from reduced fitness due to the expression of detrimental recessive mutations.
Horizontal Change
According to the young-earth model, the changes in species were horizontal and at the same level of complexity.55 However, this is not what we observe. An example is the so-called daughter species of the Bear "kind." Sloth Bears have a specialized head and dental structure that creates a vacuum device for consuming termites. Polar Bears have webbed feet and specialized fur, dentition and digestive tracts. The Panda Bear has a specialized thumb, head, reproductive system and esophagus.56 In claiming these changes were horizontal, young-earth creationists do the same thing evolutionists do: they extrapolate microevolutionary changes over long periods of time to produce new biological structures without considering the requisite organic and physiologic adaptations that are required.
Young-earth creationists claim the original "kinds" were designed with more allele variation (alleles are different versions of the same gene) than we observe in current species. According to their theory, the alleles segregated to produce today's species. This is problematic for several reasons. First, genetic differences between alleles are never very great. Second, alleles segregate randomly unless they are closely linked, in which case they tend to be inherited together. Independent alleles would have segregated to the fullest extent between the creation and the Flood-about 1,500 years by their calculations-producing all possible species well before the Flood. Third, linked alleles segregate much too slowly to support the young-earth speciation timetable.
Young-earth creationists also maintain the changes that produced new species were not evolutionary in nature. The reason, they say, is "information." Evolution involves the mutation of new genes and new genetic information. Thus, evolution is a process of progress where better and better species evolve. Speciation, on the other hand, is a degradative process. Through the reproduction of a limited number of individuals, genetic information is recombined and genes and/or gene function is lost. Thus, the daughter species have less "information" than the parent population. Therefore, since no new information is produced in their model, they say it cannot be called evolution.57,58
However, while young-earth creationists assert no new information is being produced, they do indirectly argue for new information. A gene sequence is basically a combination of letters. The information conveyed by the sequence is both syntactic and semantic-the genes occur in a certain order (syntactic information) and certain sequences have meaning attached to them (semantic information). Thus, when genes are shuffled and the sequence changes, the code changes and takes on a new meaning. Thus, the changes young-earth creationists attribute to genetic reshufflings are the result of new instructions-new functional semantic information-that is conveyed by the new, reshuffled genetic sequence.59

This is a great article by the way.
Here is one of my main problems with the super genetic "kinds" idea. From the fossil record we know that there was incredible diversity displayed in ancient times. There were thousands of separate "species" and no signs whatsoever of a Super Genetic "kind" in the fossil record. The point being, NOAH HAD NO SUPER GENETIC "KINDS" AVAILABLE TO TAKE ON THE ARK AT THE TIME OF THE FLOOD SINCE FROM THE FOSSIL RECORD WE KNOW THAT ALL THE ORIGINAL KINDS HAD ALREADY EVOLVED INTO THEIR SEPARATE SPECIES, AND HAD GONE INTO NONEXISTENCE.
I predict that IAC will not respond to the clear problems with his GFM presented above. Instead, he will respond with a one-liner, useless comment which is his way of trying to appear "confident" due to his demeaning and seemingly "non-caring" tone but which instead only serves to indicate that he has no response, and thus no argument.
