I agree we are all legal hiers thru adoption, just that there does not need to be any mapping of a woman to a legal son, what counts is being a legal heir.

The fact that sons inherited when their dads died in ancient Judaism I see as God working in that time and culture, which was very patriarchical.  The daughters got their inheritance when they married in that culture, as the ketubah or dowry, it is not the case that they received no inheritance.  The first son got a double portion, as he represented the family in that culture.

In different cultures different inheritance rules apply.
