Your example about the students is apt.

I heard a paper recently on mtDNA. A particular individual in southern Alaska, some 11,000 years old, was tested for mtDNA. It was found that his type (haplogroup A) matched individuals in the local village. But, through some mutations in haplogroup A (very much like the spelling errors in your example) this individual could also be traced directly and almost continuously (i.e., with lots of intermediate individuals) to descendants as far away as the tip of South America, with a few also in the southeastern United States. Based on when particular mutations occurred, the direction and to some degree the timing of the migrations could be determined.

Stay dry and anchored!

Clearly, this reveals the itinerary of the designer, as he traveled around introducing his designer DNA into various populations.
