I don't know that it really matters in some cases, but cultural similiarities usually require proximity as in the
spread of ceramics. This could potentially place haplogroups in geographic proximity zones in a similar way that diversity
is used to trace the origin of haplotypes. The two can compliment each other.
So, using this logic,
1. R* peoples historically swaddled infants
2. Q* peoples historically swaddled infants
3. Very few people not in contact with 1 or 2 swaddled infants
Therefore, infant swaddling could have originated amongst R and Q peoples in a proximity zone or its ancestor P-M45.
Of course, I don't take a dogmatic view on swaddling or any of this. I just find some of the correlations interesting, especially those between West Asia and the Americas. The two are so far removed and isolated, yet both appear to retain cultural aspects from a very distant past.
