American head shapes have been changing, but why?
May 14, 2012
Special to World Science
White Americans’ heads and faces have been changing in shape on average, and no one knows quite why, according to new research.
In a trend that can be identified going back to the mid-1800s, U.S. skulls have gotten bigger, taller and narrower as seen from the front, said Richard and Lee Jantz, a husband-and-wife team of forensic anthropologists at the University of Tennessee, Knoxville. They also found that faces have become significantly narrower and higher, though this shift is less pronounced than those affecting the whole cranium. . . . Read Complete Report

5 Genes responsible for face-shape found
By Trevor Stokes
Published September 16, 2012
Researchers have identified five of the genes that shape a person’s face, work that could help scientists better understand facial abnormalities like cleft palate and someday might even help forensic investigators determine what a criminal suspect looks like from crime-scene DNA.
Researchers previously knew that genetics played a large role in determining face shape, since identical twins share DNA. However, little was known about exactly which genes are involved. Three genes were thought to have roles in the arrangement of facial features, and the new research confirmed their involvement. It also identified two other genes. Read Complete Report
