Every few months we get a blazing headline about a breakthrough in genetics that will allegedly lead to super babies. This one from a few months ago is a good example of the genre. It makes for a catchy headline. Of course, the story is never as claimed, as we are not close to creating a race of mutant super babies. Instead, science is creeping up on the ability to do some very narrow gene editing to eliminate well known genetic defects. In fact, a lab has just successfully edited a viable embryo for the first time.
This is a huge step in science, but we are nowhere near close to creating the master race or even making small changes in real humans. The most recent research on human intelligence, for example, identifies 50 genes that correlate to IQ. That’s a lot of combination to sort, assuming that is the whole set of genes related to IQ. There’s also the possibility that other traits are indirectly related to those genes. Even something as simple as hair color can get wildly complex, so we will not be decanting babies anytime soon.
