Hi DDeden, I think it's important to differentiate between an allele, and a population (or an organism.) Alleles can propagate, or retreat, due to selective...
Burger et al, in PNAS, checked some skeletons from northern Europe, 7000-8000 years old (archeologically and/or carbon dated). None of them had the 13.910*T...
IMO allele and molecular clock data are very useful when parsimoniously applied with constraints (environmental, social type, etc.). Like fossil data, they are...
... Yes. Some areas have 2 high tides, others one, many vary, depending on continental geology I guess. Perhaps average 24-25 hr? ... Yes, that's true....
I think that, if the gross genetic variation (CNV) is ignored, the allele tracking and molecular clock data are practically useless. The allele tracking could...
That the specific alleles were found in all AmerIndians and only Koryak & Chukchi is far better than coincidence. I think they drew the right conclusions, to...

Those are just alleles, which can spread (through selection and/or genetic drift. I'm not talking about spread via virus, I was saying they can spread, "like"...
