I am O negative. Yes, I have an extra bit of bone on my spine. Yes, my normal body temperature is around 95.8 degrees and I look like an Aryan poster child. And gee, look, I have those noble bloodlines! I must be a reptilian shapeshifter!
Umm. No. For one thing, this "hybrid" theory is completely wrong. I have two children from two seperate marriages. My first husband was also O negative (no extra tailbone, blue eyed, reddish hair, normal body temp). Our son is...O negative. He came out a very, very healthy baby boy, weighing in at 8 lbs 10 ozs. He has the extra tailbone thing but his body temperature is absolutely normal. My second husband, by some strange twist of fate (god wanted to spare me from rhogam shots), also happens to be rh negative and is navajo. Our daughter is in excellent health, has brown eyes, brown hair, and is too young yet to really notice any things that she may have picked up from her mom's side of the family. So, two successful births between rh negative people. I wouldn't say that that is having a difficult time or being "hybrid-like". I've lost one child while in the womb at 7 1/2 weeks. 2/3 is a pretty good success rate...A hybrid species wouldn't have that much success.
Low body temperature is suggested as being affiliated with chronic illness and allergies. Allergies are very common. It doesn't take a stretch of imagination to realize that people with severe allergies probably have lower than normal body temperatures. Low body temperatures are not even that uncommon. 98.6 is just an average. Some people run warmer, others cooler. It has nothing to do with any repitilian traits.
Rh negativity is more prevalent in some parts of N. Europe, N. America and, of course, the Basques of Spain. In the obvious case of native americans, who are notably brown eyed and brown haired, this shows that the observation that rh negative people tend to be blond/red haired with green eyes is more than a little misleading. N. Europeans, like my ancestry, tend to be very fair with a higher prevalence of blue or green eyes. Of course, considering that there is a higher prevalence for rh negativity in those regions, you will end up having a good number of blue/green eyed, pale blondes running about with rh negative blood. However, that is still an extreme generalization.
There is no real pattern of rh negativity. My late paternal grandfather was rh negative, norse with brownish hair and brownish eyes. My maternal grandmother is also rh negative with black hair, green eyes. I certainly don't see a reptilian agenda pattern with rh negativity. I question any website that even alludes to it in a single sentence.
Of course, this all could be part of a reptilian disinformation plot...lol ;)
