Only 69 Years Worth of History on Tracking Rh-Negative Blood

In my prior post I questioned whether the current estimate of 15% of humans having Rh negative blood had been consistent over time.  I have since learned that the Rh factor was only identified in 1940 (by Alexander Weiner).  We’ve only been aware of its existence for 69 years!   So much for thinking about tracking it back over the centuries!

    Hello. Just because the Rh factor was only identified in 1940 doesn’t mean that the bloodlines haven’t been tracked since before then. This is only the scientific verification of what they probably already knew beforehand.
