Nurture vs. Nature

Twin studies can be an invaluable tool for scientists who are interested in studying whether aspects of human behavior are influenced by genes or environment (ie learned). Generally, this means tracking down adult identical twins who happen to have been separated at birth, getting their consent, and enrolling them in a study. Psychiatrist Peter Neubauer took things to a new level when he initiated a program that split up adopted twins at birth and then followed the differences and similarities that emerged during their lifetimes. Apparently the results of the study will be sealed in a library at Yale until 2066, however one pair of these twins has since found out about the study and they speak about the experience in the video below. Neubauer discussed the general topic of genetics and behavior in a 1996 book, Nature's Thumbprint: The New Genetics of Personality, which I haven't read but you can find here.

Is this ethical? Isn't it better for orphaned siblings to be adopted together?

Why? Separation of the soul when the embryo splits in two?

Come on. Will no one bite on the soul? Doesn't anyone out there want to argue for or against a biological basis for the soul?

The soul is epigenetic...

The biological basis for a soul was revealed in the autopsy of the late James Brown. Not only did the man have soul, he was super bad. As the 'godfather of soul' James Brown is the common ancestor of all souls.
That's funky.

Well, can't argue with that evidence.
