Police utilize facial
recognition software in many criminal cases. However with advances in
technology DNA will soon play an important role in digital forensic analysis.
Researchers impose that current identification of genes only exhibit a limited
number of physical features and more genes of relevance will need to be
discovered. Presently sketch artists affiliated with police forces and other
branches of investigation use biometrics and details of a possible suspect to
match a computer-generated image of the criminal. Manfred Kayser, a researcher at the
Erasmus University Medical Center in Rotterdam, Netherlands, states: “it’s a
start” however “we are far away from predicting what someone's face looks like”
(Kayser). The Dutch researcher and his team of colleagues analyzed DNA from
10,000 fellow Europeans by examining 9 specific “landmarks” with 3-D cerebral MRI
scans as well as an analysis of an additional eight ‘landmarks’ of facial, portrait
photographs. The identified genes unfortunately only had small effects.
Furthermore, other genes have revealed a particular influence in the distance
from the eyes to the bridge of the nose, the length of the nose, and the facial
width between cheekbones.
