O negative blood

I did a search to learn how many people have O negative blood. I found out today while participating in a student research project I have O negative blood--I'm sure I knew that but had forgotten. Anyway, mostly normal stuff about blood shortages and the RH factor came up, but the sixth thing on Google had the headline:

"Type O Negative Blood Hints At Prince Charles As Descendant of Reptilians."

I won't post the link because it crashed my browser, but subsequent searches revealed a number of conspiracies about Type O- blood including ancient astronauts, reptilian conspiracies, alien abductions, Illuminati, and so on as you might imagine. I had no idea.
