The evolution theory presents that mankind has evolved from some species of primates. We have all seen the drawing that shows the theoretical steps of the progression from the ape-creature to a standing straight up type of human man. My question is , how do you explain the Rh negative blood types ? Everything we have is passed down from ancestors, so how can a person have an Rh negative blood type and come from primates, when none of the primates have Rh negative blood ? What other specials that does not have the “monkey blood” was merged with humans to create a whole new series of blood types ?
No idea , @Yvonne Smith. We have many blood types/ antigens and I have no idea what the evolutionary advantages of any of them except perhaps for the ABO blood groups. I think I have spewed my theory on the ABO groups having something to do with our immune status since they are the only ones we know about that have naturally-occurring antibodies that correspond to those types. I have noticed that O blood types seem to hold antibody titers longer than other blood types and that AB blood types seem to hold the titers for the shortest amount of time. AB people don't have the naturally occurring Anti-A and Anti-B, while O people have both. Just an aside observation. According to Evolutionary Theory, changes that persist have a survival advantage and I can find none related to the Rhesus type, which, by the way, was first found in Rhesus monkeys.
