Mmmmkay this post is a mess, ill post some clear points on RH- in ATS style
RH is the rhesus monkey gene, so every human and most monkeys today have that gene, they have to have.
All animals have traces of their entire genetic bloodline, and this can be taken as far, as with the chicken, they are trying to stop, in early
development, and trigger some dormant genes, to make it produce a dinosaur from its genetic past instead.
Now the curious thing is, we humanity have a thing called RH-, Where a small percentage of us, are actually missing this part of our genetic history,
the RH marker is simply not there.
This could have been caused by a couple of things:
1. Genetic mutation (though unlikely, as nothing like this has happened in any other species we know of)
2. A humanoid mated with an humanoid without the Rhesus gene (that first RH- cant have been terrestrial)
3. Genetic manipulation ( Ancient alien astronaut theory )
Now an interesting fact, as the RH- people on here already hinted at, RH- and RH+ mates can have problem having kids as the RH- mother's immune
system will start attacking the fetus as if it was a foreign body.
This does happen one other place in the Animal kingdom, wait for it:
Donkey and Horse
Tiger and Lion
Zebra and Horse
Now to take it further, there are those who say the supposed "Royal Bloodline" they are keeping safe, through incest is in fact the pure RH-
