First I shall give you my take on this, from what I have read, as it is rather tricky in discerning.

OK first of all the RH component of blood types, is not an evolutionary gene from monkeys. That is a blatant mislabeling of the created gene of our blood that makes sure our oxygen carrying capacities of our human blood co-ogulates when it is exposed (or cut or is flowing openly in the air). This is life saving , as it means cuts do not have to drain all our life living blood from a cut, so that we can survive and live. This is the Lord gene, and not the Rh positive gene of monkeys or evolutionary beings of the past.

RH negative just means that life saving oxygen clotting characteristic is not there. In other words, it is the Hemophiliac gene that kills or can kill embryos or those that get it dominant as children.

All RIGHT, now we have the semantics discerned…. And separated.
