The question of why dogs were first domesticated remains unanswered. Researchers may have gotten closer to pinning down where, though. A Sept. 2009 NY Times article explains: “Sampling the mitochondrial DNA of dogs worldwide, the team found that in every region of the world all dogs seem to belong to one lineage. That indicates a single domestication event. If wolves had been domesticated in many places, there would be more than one lineage, each leading back to a local population of wolves. The single domestication event seems to have occurred in southern China, where the dogs have greater genetic diversity than those elsewhere. The region of highest diversity is usually the place of origin because a species tends to lose diversity as it spreads…A team of American researchers is examining…thousands of different sites on the dog and wolf genome, not just the mitochondrial DNA. The data have not yet been published, but some of it ‘doesn’t agree completely’ with an East Asian origin of dogs, Dr. O’Brien said. The disputes about the origins of dogs arise because researchers are just cutting their teeth on what Dr. O’Brien called ‘genomic archaeology.’” Genetic diversity among canines (dogs, wolves, dingoes) is at the heart of this research. I would suggest a simple explanation for this genetic diversity: all dogs/wolves came from one dog “kind” that came off the ark after the global flood of Genesis 7. This is exactly what creationists have said for decades. Once again, science is beginning to discover exactly what we would expect from a straightforward reading of Genesis.
