ScienceDaily has a report on a presentation Mark Shriver gave at AAAS meething this year:
"We started with 22 landmarks on the faces that could be accurately located in all the images," said Shriver. These landmarks might be the tip of the nose, the tip of the chin, the outer corner of the eye or other repeatable locations. They then recorded the distances between all the points in all directions, so they had a distance map of each of the faces. From their DNA profiles, Shriver could determine the admixture percentages of each individual, how much of their genetic make up came from each group. He could then compare the genetically determined admixture to the facial feature differences and determine the relative differences from the parental populations. "This type of study, done on admixed populations shows that each person is a composite of their ancestors and that the range of ...
