As regards "deep" trait which I did make up but I think recalls something I read... scoliosis goes back to at least Turkana Boy (1.6 millions years old). I'm also no physical anthropologist but that sounds pretty deep to me.

Evidently I was correct. There is no study that shows the Scoliosis hits all people around the world at the same rate and the incidence doesn't vary over time. How would a study like that even be conducted?
As I suspected Pooka1 is back to her old tricks of inserting completely made up nonsense to confuse readers who might not know better.

Pooka1
the relative constancy of the worldwide rate argues that it is almost extirely strictly genetics (and that humans are an extremely homogeneous species).
Once again you are making things up. The rate of genetic disease tends to vary greatly around the globe.
I'm going to google the first genetic disease the pops into my head.
Ok it's Cystic Fibrosis.
Although technically a rare disease, cystic fibrosis is ranked as one of the most widespread life-shortening genetic diseases. It is most common among nations in the Western world. An exception is Finland, where only one in 80 people carry a CF mutation. In the United States, 1 in 4,000 children are born with CF. In 1997, about 1 in 3,300 caucasian children in the United States was born with cystic fibrosis. In contrast, only 1 in 15,000 African American children suffered from cystic fibrosis, and in Asian Americans the rate was even lower at 1 in 32,000.
Prevalence of congenital colour blindness among Inuit in East Greenland.
RESULTS: Only 1.0% of male Inuit (3/290) are colour blind, a significantly lower incidence than the 8.7% among Danish males in Denmark (15/173). The prevalence was the same in the three control groups, Danes in East Greenland, immigrants and Danes in Denmark. Deuteranopia is the most common type. Females showed the same low prevalence in all four groups.

OK, I know I promised I wasn't going to post anything else, but nothing I've read indicates that there *is* a relative worldwide constant rate for scoliosis. I saw a study from China listing an incidence of .064% all the way up to one from South Africa listing an incidence of 8%. I have no idea what that means in terms of genetics (and I suspect noone else here does either), but there's no point in arguing about conclusions drawn from a fact which is not in the slightest a fact.
As long as our children are diagnosed with Idiopathic Scoliosis, they are suffering from a disorder for which the cause, by definition, is unknown. That is the only fact in evidence.

Suggest you read the section, "Human Diversity Today". Johanson is a prominent physical anthropologist.

The deal appears to be that the high degree of genetic homogeneity in humans is due both to humans as a species being relatively new (~150,000 years) and there being some probable evidence for a bottle neck in the population ~50,000 years ago.Sharon, mother of identical twin girls with scoliosis

Dr. Kiester) The more active the better. The natural incidence of scoliosis is falling. I believe it is a function of increased girl participation in sports, and increased obesity (which reduces scoliosis to a degree in some cases by moving the center of gravity forward away from the spine).
So Dr. Kiester, an orthopedic surgeon doing research of scoliosis at UC Irvine, believes that the natural incidence of scoliosis is falling....he thinks due to obesity. I ran across a medical article that said the use of forceps in delivery had been falling over the past couple of decades. Perhaps hidden trauma associated with forceps births has been decreasing due to that and therefore the incidence of scoliosis in athletes is also falling. Interestingly, neither one of those ideas would be considered genetic. And why would a genetic trait be decreasing anyway?
I guess the alpha-scientists will need to show Dr. Kiester what's what and put him in his place for not following the accepted scoliosis research agenda these days.Last edited by Ballet Mom; 02-01-2011, 08:45 AM.

Extensive evidence from mouse strains with spina bifida indicates that there is sometimes a genetic basis for the condition. In human spina bifida, as with other human diseases such as cancer, hypertension and atherosclerosis (coronary artery disease), spina bifida likely results from the interaction of multiple genes and environmental factors.
Research has shown that lack of folic acid (folate) is a contributing factor in the pathogenesis of neural tube defects, including spina bifida. Supplementation of the mother's diet with folate can reduce the incidence of neural tube defects by about 70 percent, and can also decrease the severity of these defects when they occur.[16][17][18] It is unknown how or why folic acid has this effect.
Spina bifida does not follow direct patterns of heredity like muscular dystrophy or haemophilia. Studies show that a woman who has had one child with a neural tube defect such as spina bifida, has about a three percent risk of having another child with a neural tube defect. This risk can be reduced to about one percent if the woman takes high doses (4 mg/day) of folic acid before and during pregnancy. For the general population, low-dose folic acid supplements are advised (0.4 mg/day).
