What IS interesting about Rh- blood is that it seems to indicate that there are separate species of man vs human, since, without the recent advent of the Rhogam shot, viable pregnancies between Rh- and Rh+ parents would be severely limited. Also, Rh- people tend to have lower body temps overall, lower blood pressure overall, sometimes an extra rib, and sometimes a caudal tail more often than Rh+ people. The races are clearly different species.

Another point of interest is that nobility and US Presidents for the last 50 yrs have Rh- blood. This is what gave rise to the term "Blue Blood" (not to be confused with "Blue Babies") since Rh- blood carries more copper than iron. Even the emperor of Japan is reported as being O-, despite Rh- being EXTREMELY rare in Japan.

As to its origins, the scientists' explanation of

>idk, therefore, ignore this inconvenient fact

doesn't cut it. They claim it is a blood mutation, yet no other genetic mutations on blood markers exist, and they can't account for such a sizeable one-time anomaly. Fishy.
