Conclusion on primogeniture: early readers of Genesis would very likely have understood Adam as having higher authority due to being made first; Genesis 2 is the rule, not the exception.

Mike concludes that Genesis 2 stands as a case of the primogeniture rule (not exception) because there's nothing in the passage telling us otherwise. Unlike Jacob, Joseph, or David -- all clear exceptions with specific narrative markers -- Adam and Eve's creation account has no exception indicator. Early readers would very likely have seen Adam's being made first as implying higher authority.
