Twins have always held a certain fascination to human kind. Now they may hold the key to determining whether or not human beings have the ability to morph or effect their appearance biologically from within.
The study of facial differences between identical twins raised apart by adopted parents could hold the first clue. Identical twins are never exactly identical. There are minute differences that arise in their faces over time. For example, the average variation in distance between the two eyes could be + or – 1.3 millimeters between twins raised in the same family. The average variation of other facial features could be quantified as well. First, quantify those variations between twins raised in the same family. Then do the same for twins raised apart.
What if the twins raised apart have different average variations? Would it then be possible to compare the facial variations with the facial features of the parents who raised each twin? Could we find that humans morph slightly to look like the people who raised them? This would certainly be an evolutionary advantage. We tend to treat people who look like us, a little better.
In the future we could see parents adopt and adapt their kids by cranking up that inherent morphing ability somehow.
