Why Blood is so interesting

[SquishyStarfishy]

Being a blood donor and O negative. I have always been really fascinated about blood (some of my friends swear I'm a vampire)



But actually apart from all the mumble jumble Biological stuff they found out. Blood actually has a few conspiracy theories tied to it.



For example, did you know that

* Chimpanzes are mainly Type A Blood with a few being type O but never type B.

* While Gorillas are Type B with a few O and never type A.

* SO how do you get a human who comes from apes apparently with O being the most common type not to mention we have A, B and AB as well. Interesting aint it.



The next interesting thing I found was what I actually wanted to talk about ...

There has been evidence that humans actually originated from two human species.



If you google Rh negative origins, there are a couple sites that can prove this fact.



It shows this is possibly the case, based on the fact that a mother who has negative blood would reject a baby who is positive and this doesn't occur anywhere else in the animal world, apart from when a horse and donkey mate to make a mule. Here we have two seperate species.



So yeah, Blood, is not just that eeeuwy mind boggling stuff of vampires. It is actually pretty interesting really.

Wow I know there were multiple Human Species who eventually died out, but I didn't know about the theory that modern humans may have originated from 2 distinct species..
