Sorry I forgot to add the second part of their magical explanation...

Hardy-Weinberg Equilibrium
The other important factor to be considered in this scenario is something called genetic (Hardy-Weinberg) equilibrium for the gene frequencies of a particular population of organisms. The change in gene frequency is used in evolutionary theory as evidence for microevolution, but this theorem can also be applied to a creation scenario since it does not involve the formation of novel genes from no genes. Hardy-Weinberg theory states that gene (or more accurately, allele) frequencies will remain constant as long as these requirements are met: random mating, no migration in or out of the population, no mutation, no genetic drift (chance changes in gene frequencies), and no selection for traits.
When the animals left the Ark none of these conditions would be met, enabling microevolution (change in allele frequency) and speciation events. These events include the selection of mates (for humans specifically), environmental selection of some traits, accumulation of mutations, chance genetic drift, and migration of animals taking with them different combinations of genetic material. Because of the small populations of animals immediately after the Flood, gene (allele) frequencies would rapidly be altered as animals migrated around the globe, adapted to various environments based on their genetic constitution, and became reproductively isolated.
This would result in many variations of the original animals on the Ark, just like artificial selection produces many variations in domestic animals. This is not just a creation paradigm. Many population genetic studies, for any animal, include migration and reproductive isolation leading to speciation. The migration of humans around the globe is well-documented and based on the changing gene frequencies (such as ABO blood alleles and mitochondrial DNA) in each population. It is also well documented from DNA and protein sequences that all animals had migratory events that contributed to the ecological, behavioral, and geographic speciation events observable today.

All of the examples given above do not require creation of new genes or genetic information via natural processes from genetic information not previously in existence (evolution). The genetic information we observe today was supplied at the time of creation in these animals in their genomes, and their genetic potential has created the variations frequently classified as species. It is true that mutations create many new variations, but this is not an example of Darwinian evolution. Mutations work on pre-existing genetic material, are accompanied with a loss of information, and lead to extinction, not the conversion of one animal kind into another animal kind, regardless of how many years mutations are given.
