I know that my mother, who is half-Italian and hence more likely to have more "Neolithic" ancestry did not develop wisdom teeth, while I had all four instead (one of them impacted, the other three not because I had already lost molars by then - sweet tooth that I am) and so do most of my direct relatives (which are only 1/4 or nothing North Italian).Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-86177165250357781162012-03-13T10:24:12.679+01:002012-03-13T10:24:12.679+01:00In Britain 35% of people today do not develop wisd...In Britain 35% of people today do not develop wisdom teeth - although sharing 'similar' diets.<br /><br />I would imagine that this therefore genetic rather than environmental. As she is cro-magnon and about the same percentage with wisdom teeth have that haplogroup, is there a correlation?<br /><br />RJLBobhttps://www.blogger.com/profile/16886732338349957214noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-74006849948772629162012-03-09T11:55:30.513+01:002012-03-09T11:55:30.513+01:00I can't say because I could not find the paper...I can't say because I could not find the paper. It'd be interesting to see case by case. Still I strongly suspect that it has more to do with cooking traditions than economical model.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-20185860373626154102012-03-09T10:45:37.990+01:002012-03-09T10:45:37.990+01:00What about populations showing rather common trait...What about populations showing rather common traits such as a broad jaw despite having switched to a herder diet for millenia ?Heraushttps://www.blogger.com/profile/07032921971763481466noreply@blogger.comtag:blogger.com,1999:blog-3023805782808412230.post-56908129646033886932012-03-09T10:30:57.149+01:002012-03-09T10:30:57.149+01:00Yeah, there have been several studies recently arg...Yeah, there have been several studies recently arguing for a significant role of diet on not just jaw, but also skull shape. Of course this is a difficult topic, because clearly there are genetic predispositions, as well.<br /><br />The tooth-crowding as caused by more modern diets is believable, since selection should have ensured functional and pretty teeth, but probably does not work on a few 1,000 years time scale on something rather weak. Of course, our jaws have become less robust over the past 200,000 years or so anyway, so there is another contributing factor.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.com
