Christians to die out by diminished gene pool theory (sub-species)

[brewer]

The numbers involved would be in the range of <50,000.  So there are plenty of believers still to avoid issue.

We are seeing genetic problems, and serious ones at that, in some of the Amish communities, however.

The Hutterite's have their own genetic autosomal recessive disease.

"Affected Populations
Bowen Hutterite syndrome appears to affect males and females in equal numbers. Since the disorder was originally described in two brothers in 1976 (P. Bowen), over 20 cases have been reported in the medical literature. Most affected individuals are Hutterites. The Hutterites are members of a religious sect (Anabaptists) originally from Moravia who live communally in certain regions of the United States (e.g., Montana, North and South Dakota) and Alberta, Canada."
