Boundaries of the I-Function in Twins Identical, conjoined, and half-twins are all examples of intrinsic variability in humans. Intrinsic variability exists in all animals and is an adaptive mechanism built into the nervous system in response to input. This mechanism allows humans to distinguish the same inputs as different from one another and therefore, the possible outputs vary with time. It is possible that due to identical genetic input, the twins could share identical neural pathways and
Conjoined Twins: Two Individuals, One Body Conjoined twins are a rare form of identical twinning; one that carries many challenges with it, to affected twins and their families. From the time of birth conjoined twins must struggle to survive against physical and psychological difficulties. With the premium that current culture places on independence and individuality, conjoined twins fight to find their place in society, meanwhile demonstrating coexistence at the extreme.

1.0 Introduction I have always been fascinated by conjoined twins and have always had questions about them like; what do the Siamese have to do with conjoined twins? Why does this form of twin happen? What, if any genes cause this? What types of Conjoined twins are there? How does the environment affect, if at all, the biological families' gene pool? In my research in efforts to prepare this paper, I found the answers to this question and many more. This term paper will cover the types of conjoined
