TLC had a show the other day title "I am my own twin". I missed half of the show but it involved a case where a mother had to prove that her own children were hers despite the fact that a genetics test said otherwise! It turns out that she was a chimera, an individual formed from the fusion of two zygotes. The interesting thing is that cells throughout the body can be from either zygote. In cases where a male and female combine, a hermaphodite forms. They showed one baby that had a clear line of different colorization in the skin right down the midline of the belly. (it immeditatly brought to mind side show half man half woman imagary)
I wonder how many souls religions would say they have?
