What’s YEC explanation for the emergence of races?

This is just something I got while watching my favorite station (Discovery Channel).Apparantly based on the lack of any significant differences in human DNA they surmised that at one point in history the human was near extinction. Apparantly there should be more variation in DNA. Using the knowledge of mitochondrial DNA and that it has a nearly set mutation rate they have been able to back track and give this near extinction time at sometime 70-80k years ago. It is surmised that the human race was cut down to roughly 10k members and that is what accounts for the lack of variation. They attribute this to a "super volcano."

PB: More ad hoc evo-blahblah-explanations on 'mind control'. Contemporary biology has demonstrated a very recent origin of homo sapiens-->Creation. See also my comments on the ZFY region (the region for which they have to postulate this nonsense).
Evolutionism = science fiction.

I just thought the program was interesting. It tied in the notion of a "super-volcano" and what its eruption might do to life on Earth. Apparantly there is a "super-volcano" forming under Yellowstone National Park.Here are some Yellowstone supervolcano links:http://www.solcomhouse.com/yellowstone.htmhttp://armageddononline.tripod.com/volcano.htmNASA Lowers Sights to Predict Volcano's Eruption | Space[This message has been edited by RedVento, 01-14-2003]

​

PB: And therefore humans went through a bottleneck 70 ky BP? What happened to logic?

The logic is this:The last super-volcano eruption was 70-80k years ago. Based on the a realtively fixed rate of mutation in mitochondria they can trace back the relativly few number of deviations in human mitochondria to that same time frame. The theory I believe is that the effects of a super-volcano eruption 70-80k years ago killed off a large number of early humans which is why there are such a low number of genetic differences in us today. The supervolcano eruption is the cause of the bottleneck.

PB: reference please

​

PB: You mean the NONRANDOM mutations in mtDNA? Listen, RV, I have demonstrated recently that the mutations in mtDNA are non-random mutations. The molecular clock is very, very doubtful at the least (according to the mtDNA data human and chimp have a common ancestor 150 ky BP. Funny, isn't). I think Dr Page is making overhours at the moment to solve this little evolutonary inconvenience.

​

RV: they can trace back the relativly few number of deviations in human mitochondria to that same time frame.

​

PB: No they CANNOT since they CANNOT exclude non-random mutations. The whole story is based upon randomness of mutations. And since non-random mutaions have been scientifically demonstrated the whole story is invalid.

​

RV: The theory I believe is that the effects of a super-volcano eruption 70-80k years ago killed off a large number of early humans which is why there are such a low number of genetic differences in us today. The supervolcano eruption is the cause of the bottleneck.

​

PB: The ZFY region mutates also NON-RANDOMLY so all the conclusions from this region are completely invalid. You, indeed, have faith in science fiction.

Every one of the links I posted referenced the last eruption, and all I said was that it was interesting. And I do have faith in people who are presented as doctors in relevant fields, rather than in a book of dubious origins and those trying to prove its validity. But that's just my opinion. Best Wishes.
