twins, fraternal twins, semi-identical twins, hermaphrodites...i don't know what kind of other details to include. its a simple question, the tricky part is, IS there someone out there reading this question with enough brain power to answer this question properly?? I want educated results!

one case appears to have been confirmed very recently, in this case one of them was a hermaphrodite because he was a chimera. What I am wondering is, would such cases always neccessarily be disastrous like that, because me and my brother are both completely normal, and, how can I go about confirming wether I am or not really a "half-identical twin", is there any test the doctor can make on me to see if this is the case or not, and would he definitely have noticed when I was born if that was the case?
Thanks.

I was in my biology class when the teacher asked us this question "what are humans". This boy answered animals and the teacher said that was right, but I said no were not animals and everybody looked at me like I was stupid. Then the boy said "were warm blooded which makes us mammals and mammals are animals so were animals too". I really dont know why were animals because I dont think were animals.So if somebody can clear this up for me.
