A new strategy for capturing the 3D shape of the human face draws on data from sibling pairs and leads to identification of novel links between facial shape traits and specific locations within the human genome. Hanne Hoskens of the Department of Human Genetics at Katholieke Universiteit in Leuven, Belgium, and colleagues present these findings in the open-access journal
PLOS Genetics.
The ability to capture the 3D shape of the human face and how it varies between individuals with different genetics can inform a variety of applications, including understanding human evolution, planning for surgery, and forensic sciences. However, existing tools for linking genetics to physical traits require input of simple measurements, such as distance between the eyes, that do not adequately capture the complexities of facial shape.

If America wants to prevent another event like Wednesday’s storming of the Capitol in Washington, DC, officials should make all efforts possible to arrest and prosecute every single person involved in the violent protests events that some branded as an attempted coup by President Donald Trump and his supporters.
This is not simply a matter of vengeance. It’s a real-world example of a common concept in criminological theory focusing on the best way to use punishment to deter future crimes.
In criminology, there are three levers for fighting crime, as the late Mark Kleiman previously explained: swiftness (how quickly someone is punished), certainty (the likelihood someone is punished), and severity (how harsh a person’s punishment is) established way back in the 1700s by an Italian criminologist called Cesare Beccaria.
Genetics of human face begin to reveal underlying profile
Using 3-D facial images with over 7,000 data points, researchers have identified changes in the DNA sequence of European individuals that contribute to variation in facial features. These findings help us better understand human variation and facial birth defects.

UNIVERSITY PARK, Pa. The genetics behind the shape of the human face are difficult to decipher, but now an international team of researchers has connected specific genetic signals with specific areas of the face. They not only can see the signals of normal facial features in the genome, but also hope their work can shed light on craniofacial malformations such as cleft lip and palate.

“The face tells the outside world about your identity, who you are related to, where your ancestors come from, and even your health,” says Julie White, graduate student in anthropology at Penn State. “But we only know a fraction of how faces are formed. The facial structure comes together in early development, and if it doesn’t go right, you can get a cleft palate or other problem, but we don’t fully know what controls those processes.”
