There are two conceptual models that overshadow current theories related to the production of diversification within organisms.
Darwinian evolutionists propose that genetic variability is the result of random mutations that have accumulated gradually over millions of years. In contrast, creationists generally assume that God made all useful genetic information during the creation of the world.
Both largely agree that groups such as the Family Canidae evolved from a common ancestor, and the rapid development of variety during the domestic dog breeding, was simply the result of shuffling preexisting genes. This common genetic theory fails to explain the rapid production of the significant diversity when presented with the assertion that the wolf was a pure breed while in nature.
A purebred organism is a genetic homozygote for the characteristics in question, and will therefore pass its traits to every offspring produced. In other words, wolves only give birth to wolf pups, but from them a tremendous genetic and morphologically diverse number of dogs have been isolated in a relatively short period of time.
Explaining this conundrum cuts to the very heart of the creation vs. evolution controversy.
The canine baramin (Biblical kind) likely speciated rapidly following the flood of Noah during geographic radiation, and each new population was then naturally selected until varieties such as the wolf, fox, hyena, jackal, etc., each became purebred.
Selection is the process of inbreeding specific genes from a diverse genotype until alternate variations of genes (alleles) are eliminated, and the bloodline will only then breed true.
As a result, the purebred organism is genetically limited, and in many respects the wolf should be considered no different in its ability to produce offspring diversity than any of the dog breeds we have today. Although speculative for some time, genetic studies have now thoroughly established that dogs were bred from domesticated gray wolves.
It is also a matter of historic fact that most breeds have been selected to purity within the last few hundred years. However, when compared to the wolf, the domestic dogs are found to have divergent sequences not possessed by their progenitors.
Due to these findings some geneticists now believe that wolf domestication must have begun more than 100,000 years ago despite the fact that archaeological findings can not verify their existence beyond 14,000 years.
If one believes that the Biblical flood of Noah was a recent and global event, then another problem presents itself. Genes have fixed locations within the genome called loci, and sexually reproducing organism only carry two alleles (variation of a gene) per locus.
If the number of breeding pairs released from the ark can be taken as accurate data for this recent genetic bottleneck, then the maximum number of original alleles is known.
According to the Bible, no more than seven breeding pairs were preserved for each baramin, and these 14 individuals can only carry 28 alleles per locus. Since only 8 people were alive following the flood, there should be a maximum of 16 alleles at any given locus in humans.
However, it is now clear that many genes exist within populations as hundreds or even thousands of alleles. For example, 240 alleles have already been discovered in the human HLA-B locus.
In spite of such concrete evidence, most creationists still tend to assume there is no mechanism for generating new genetic information, and indeed the following quote may be exemplary of the current state of thinking regarding intelligently designed genetic heredity.
"Recombination explains why children look different from their parents.
This shuffling of the genes can produce superior combinations of different genes. However, because we see that mutations are incapable of supplying useful variation, the useful genes that are there to be shuffled must have been created at the beginning.
