> Do certain physiognomies become more common due to the age they live in/environmental factors like diet? Would a highly processed diet of today’s world birth more circular features/overbites? Yes and no, circular features are not regressive features, this is a common misconception. They're just a trade off. Some of the smartest, healthiest and highly intuitive people are spherically influenced in the face. > Sorry - I meant as in a processed diet can add fat around the face, making it appear more circular? This could happen due to excess water retention in the face and bloating, absolutely! But the appearance changes the energy too. It does hide the "true face" (I mean their genetic imprint) - but it also provides information on the current state of the person. You can't hide physiognomy.
