The identity in the primitive society was based on consanguinity .
原始社会存在身份,但这种身份是建立在血缘基础之上的。

反之,夏威夷的亲属制度,却以通常都是这种情形的家庭为前提。
The code lays down other requirements in addition to the form of marriage , such as degrees of consanguinity and affinity , and the need for the consent of guardians in some cases .
