Researchers are zeroing in on the alleles that result in certain facial traits.
See:

There are some nice drawings of the traits they mean.
We might soon actually get some data about what our ancestors looked like other than the often fanciful renderings of artists based only on a skull.
Of course, I'm sure there will in the future be parents who want to mess about with changing their offsprings' appearance by changing these alleles. Designer babies, indeed.
