I am Sadly Lacking in
Atlantean or Alien Ancestors

From PZ Myers at Pharyngula:

Did you know that “PEOPLE WITH RH NEGATIVE BLOOD MAY BE DESCENDENTS OF EXTRATERRESTRIALS OR ATLANTEANS”? I learned it on a site called Spirit Science, so it must be true. And their logic is impeccable: the Rh- phenotype is rarer than the Rh+ phenotype, therefore it must be specialer, therefore it must have been inserted into the genome by aliens, and implicitly those aliens love sticking things in people, so QED.

There are also some curious assertions.

So, if all mankind evolved from the same ancestor, their blood should be compatible. Do you get what I’m saying? If we had all evolved from the same ancestor, we would all have the same blood.

Continuing with that logic, if we had all evolved from the same ancestor, we would all have the same hair.
