That's why I wonder if epigenetics may have something to do with that. <br /><br />I cannot find the original comment at Dienekes (rather recent) that mentioned that. The author noted that the difference was brutal of 8 or maybe 12 CI points (from memory), so I suspect that a mere sample bias can hardly be the reason.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3563811638411839784.post-62308021840116248492009-06-30T17:44:28.404+02:002009-06-30T17:44:28.404+02:00In the case of Germany, some information on region...In the case of Germany, some information on regional demography may be crucial for the correct interpretation of these CI figures.<br /><br />In the first half of the twentieth century, at least, the average CI of the northern half of Germany was dolichocephalic, and the average CI of the southern half of Germany was, like other areas in and around the Alps, brachycephalic. If the northern half of Germany had a greater total population, then the average CI of Germany as a whole might be dolichocephalic even while the south of the country maintained its previously noted tendency toward brachycephaly. It may also be a simple matter of where in Germany the majority of the sample has been obtained. I would rather attribute such a rapid "change" in the reported CI of Germans to demography and sampling bias rather than to an epigenetic phantom.Ebizurhttps://www.blogger.com/profile/16925110639823856429noreply@blogger.comtag:blogger.com,1999:blog-3563811638411839784.post-19899957654190228422009-06-30T10:58:13.227+02:002009-06-30T10:58:13.227+02:00Well, I would not be surprised if it affected some...Well, I would not be surprised if it affected some of our most plastic inheritance too. For example, someone mentioned elsewhere that Germans have rapidly evolved from mostly brachicephalic to mostly dolicocephalic in just 70 years (since 1940). This can't be attributed to a genetic change but could have been affected by epigenetic changes maybe promoted by food or whatever other reason.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.comtag:blogger.com,1999:blog-3563811638411839784.post-12352106747036546352009-06-30T10:39:25.923+02:002009-06-30T10:39:25.923+02:00I think Epigenetics is an exception and can be saf...I think Epigenetics is an exception and can be safely ignored.
