Last year, the dark-skinned, blue-eyed facial reconstruction of Cheddar Man, a 10,000-year-old British resident, made international headlines and sparked discussions about native identity in a nation grappling with Brexit and issues of migration..

The determination of facial appearance, health history and future health risk from DNA is has great potential (Claes et al., 2014; Kayser, 2015; Toom et al., 2016) but caution should be expressed with respect to assumptions, interpretation and individual confidentiality as there is a significant threat to an individual in obtaining healthcare insurance (Hallgrimsson et al., 2014; Idemyor, 2014; Toom et al., 2016).

Information on an individuals facial morphology can have several important clinical and forensic applications; informing patient specific models, improving and reducing the need for extensive surgical interventions for craniofacial anomalies/trauma, prediction/reconstruction of the facial form from skeletal remains, and identification of suspects from DNA (Stephan et al., 2005; De Greef et al., 2006; Wilkinson et al., 2006; Beldie et al., 2010; Popat et al., 2010, 2012; Richmond et al., 2012; Al Ali et al., 2014a; Shrimpton et al., 2014; Farnell et al., 2017; Richmond S. et al., 2018).

I notice that many folks from the South and Lower Midwest (especially Kentucky, Indiana and Tennessee), where Irish and Scottish ancestry are the most They just released a fascinating study which aligns many pictures of individuals from every country and created composite images of what the average face would look like. In cleft lip tissue, limited evidence was found for an association between LINE-1 methylation and maternal exposures but conclusions were limited by modest sample sizes (Khan et al., 2018). PLoS Genet. Indeed, previous studies have demonstrated that self-perceived and genetically inferred ancestry are associated with facial morphology, particularly with regards to the shape of the nose (Dawei et al., 1997; Le et al., 2002; Farkas et al., 2005; Claes et al., 2014).

The faces are narrow, you might say hollow. B., Manyama, M., Kimwaga, E., Mathayo, J., Larson, J. R., Liberton, D. K., et al. Historically, craniofacial genetic research has understandably focused on identifying the causes of craniofacial anomalies and it has only been within the last 10 years, that there has been a drive to detail the biological basis of normal-range facial variation.
