North America Settled by Just 70 People, Study Concludes

For some mysterious reason, the study cited in the article omitted the Nephites, Lamanites, Mulekites and Jarrodites

I'm shocked.

I know I know I know........because they are the fiction of a deluded individual(s).

“Effective” size is the equivalent to a founding population. But that’s 70 breeding adults, plus elders, children, and their descendants. A closely related band of hundreds would still have the “effective” size of 70 unrelated people.
A thousand people isolated in Siberia for a few thousand years intermarrying would also have the same limited genetic variability.

The death rate at childbirth could not have been that high. Prior to hospitals, the death rate was 5-10% per childbirth. It was only in the 1800s when women were in hospitals with doctors coming in from dissecting corpses and spreading “childbirth fever” that the death rate for child birth was 30-50% - and the rate was much lower for women using midwives at home.

You’re right. There were 71—but one was gay and didn’t leave any progeny.

Thanks kitchen. This is a trivial result of what must have been an expensive and pointless study. The only thing that can be known for certain from studying DNA from living populations is what genes and chromosomes exist in the living population. Sometimes some shared (genetic) ancestor can be determined -- because the survivors survived -- but most emphatically *not* the geographical origin. To all -- please ping me to other topics which are appropriate for the GGG list.

hehehe loin springing.....

Impossible without disastrous birth defects.

North America Settled by Just 70 People

And two of those settled W.Va.

Folks, I conclude that these 70 individuals were world-class sexual athletes to produce the millions of Amerinds who sprang from their loins.

Not at all. It could easily be done.

Back in high school I and a fellow computer geek friend of mine set out to show, mathematically, that it was impossible for Noah and his passengers to have possibly reproduced sufficiently to have enough progeny to end up with the then total world population.

Our formula was fairly complex, and intentionally very conservative. We tried to allow for lower-end birth rates, low child-survival rates, young death rates, generational wars and epidemics reducing population... everything we could think of. As it turned out... even with our most conservative formulas, it turned out that the total world population might still have been several times what it is now. We had to conclude that it was entirely reasonable that Noah and his progeny could have produced the current world's population, easily.

Do you have a web source for this tree?

Actually I was shocked at how many. Seems if you made it out of childhood your chances were pretty good.

Well, yeah.... Even the Old Testament says, "The days of our years are threescore years and ten; and if by reason of strength they be fourscore years..." (Psalm 90:10)

If that’s the case, then the Indian population of North America at the time of Columbus would have been approx. 43 billion people (assuming an average annual growth rate of 1.5%).

One of the comments to the “music” video:

“i have to admit, his dancing is freakin awesome! i wish we still had music like this pouring out into our society.”

Dancing? It looked to me like he swallowed a ferret and it was chewing its way out. At least it was appropriate to the banality of the “music” and the idiocy of the “lyrics.”

You certainly widened the scope of your formula to allow for all sorts of Malthusian maladies.

But you appear to have missed one of the most important impediments to the uncontrolled and dangerous geometric progression Malthusian maladies in N. America appears to have been missed.

I refer of course to the stampedes of huge herds of mammoths, stretching as far as the eye could see, wherein thousands of tiny tykes would be stomped to death under the thunding hooves. Sad, of course, but indisputably true.

By the way, some scientists are preparing to clone these massive marauding monsters into our peaceful world even as we debate the 70 DNA strains. Remember, the plan of the Liberals to disarm us so we won’t have guns to defend ourselves from cloned mammoths. I have tried to bring this warning to all our Freepers for years.

Verily I cry woe! and Whoa! For it won’t be long before the Great Plains become the Great Pains for modern citizens who don’t know one end of a fluted Clovis point from a pointed flute.

But I digress...

...most experts agree...

It almost has the ring of a logical fallacy to it.

[wolfcreek]

Some of the Clovis people just can’t let go. ;>)
