![Are Faces Made or Born? Twin Studies with Dr. Mike Mew and Prof. John Mew
Are our faces shaped by genetics or environment?
In this discussion, Dr. Mike Mew and Prof. John Mew analyze twin studies, craniofacial dystrophy, and the debate of nature vs. nurture in facial growth.
The conversation reviews scientific evidence from Horowitz (1960), Lobb (1987), Corrucini (1985, 1990), Carels (2001), and Khan (2020), along with broader research into craniofacial variation, orthodontics, and environmental influences such as breathing and diet.
