human chimera (no kidding!)

a woman underwent testing to find out if she could donate a kidney, and somehow found out she's biologically unrelated to the children she concieved and gave birth to normally. turns out she is actually twins that fused together in the early stages of pregnancy! truth really is stranger than fiction sometimes!

Chimerachism isn't all that uncommon, it's jsut that in most cases in more minor. Most cases, the only remains of a mingled fetus are bizarre pigmentation on certain places on a person's body (namely the back) However, stranger stuff have been reported, such as out of place organs/ ears, ect.

thats very interesting. I have never heard of anything like this before, i might have a look up about it

Wow, that's really interesting. That would be quite the shock to discover about yourself.

What? That you have other people bits floating around in your DNA that was potentially another twin? Yeah, that might qualify. It's pretty creepy think that those blotches on your back might have been a brother of yours...
