A Historical and Geographical study of the Ainu in the Mid-nineteenth Century

人们认识到，流动的居民群体具有确保定居成员之间可持续的血缘关系的作用。同一家庭(定向家庭)的居民成员主要由于婚姻而分散到不同的定居点。随着他们的每个新家庭(生育家庭)，他们和/或他们的近亲将他们的家搬到另一个定居点，与他们的定向家庭成员居住在一起。据估计，主要由近亲建造的定居点能够在狩猎-采集社会中继续存在，而不会随着时间的推移削弱定居点成员之间的血亲关系。因此，可以推测，定居成员之间的可持续血亲关系是通过流动的居民群体产生的。

It is recognized that fluid residential groupings had the function of ensuring sustainable blood kin relationships among settlement members. The resident members of the same household (family of orientation) spread out into various settlements primarily as a result of marriage. With each of their new families (family of procreation), they and/or their close kin then moved their home base to another settlement to reside with members of their family of orientation. It is estimated that settlements constructed mainly by close blood kin were able to continue to exist in hunter-gatherer societies without weakening the blood kin relationships among settlement members over time. It can therefore be postulated that sustainable blood kin relationships among settlement members occurred through fluid residential groupings.
