To be clear, I am not arguing that nuclear and extended families are exclusive of each other. I think most of the people arguing against me are confused about this. Anthropologists dichotomize societies by nuclear family vs extended family because Western societies basically don’t have extended families as an important social unit at all, whereas in many societies the extended family is an important social unit. And the difference usually has a lot of implications. Hence the dichotomy being useful. But this does not mean that in societies where extended families are important that they are more important than nuclear families. And really this shouldn’t be surprising: we’re not bees. We form reproductive pairs. Our children are twice as related to us as our nieces and nephews. There’s no way it could ever come to be that the nuclear family would not be the primary human social institution.

Like with low birth rates, this appears to stem more from modernity than anything else. Both Western and non-Western societies placed more of an emphasis on extended families in the past, and both have placed less of an emphasis on them as they've modernized. Western societies have been at the forefront of a lot of modern changes, so these changes were more noticeable in them.
