We may well ask whether such elaborate vertical cultural transmission could occur at all if females were dispersing from natal groups, as happens among chimpanzees.
Most of the juveniles presumably disperse far from their natal areas, whereas adult birds are territorial and remain on breeding grounds all year.
Scaling of natal dispersal distances in terrestrial birds and mammals.
Remarriage was sought by those women who married in their natal households.
In addition, larval performance was studied over a relatively long time period (16 days), which should reduce potential carry-over effects from natal host plants.
Through gift-giving, women are cementing exchange relations with their natal kin as security against extreme adversity.
Perhaps even more common was the adoption by their natal family of a marriage strategy formerly considered unusual and undesirable: uxorilocal marriage.
A clinically significant association existing between autism and wild measles infections (prenatal and post-natal) is unlikely.
