I am dumb, I am aware. If twins have the same DNA, are they the same person from a biological standpoint?

    It isn’t really nature vs nurture, it’s nature interacting with nurture. Steve Jones, the biologist explained it beautifully with reference to Siamese cats:

    Siamese cats are light brown with dark brown fur at the tips of their ears, feet and tail. But if you raise one in a very warm environment, they will be light brown all over. A very cold environment, they will be dark brown all over. There’s a gene switching the fur colour but its action depends on the temperature.

    There are many different ways genes and environment interact, there’s no real ‘argument’ here. It is simply true and, because genes and environment are often so closely linked, it’s often complicated and sometimes impossible to tease out what’s causing what.
