Traditional ways of distinguishing populations are irrelevant in terms of genetic code.

Transposons are just small pieces of DNA that randomly insert in the genetic code. And if they insert in the middle of the gene, they disrupt its function.

We are going from reading our genetic code to the ability to write it. That gives us the hypothetical ability to do things never contemplated before.

We can do genetics. We can do experiments on fruit flies. We can do experiments on yeast. It's not so easy to do experiments on humans. So, in fact, it helps us, to interpret our own genetic code, to have the genetic code of the other species.

We can create new ways to create clean water.

Even with seemingly simple things like eye color, you can't tell from my genetic code whether I have blue eyes or not. So it's naive to think that complex human behaviors, like risk-seeking, are driven by changes in one or two genes.
