I didn't mean to suggest that "asking parents to be more active than they normally would be around their young children" is a practicable experimental modality - I was simply thinking through the methodological logic to come up with ways in which genetics could, logically, be controlled for. Clearly, somehow incentivizing parents to be more active than they normally would be fits the methodological bill, althoug it's certainly impractical, as you point out. <BR/><BR/>Thanks for correcting me on the Christmas issue; I didn't spot that at all. I'll strike that bit of my entry.Anony Mousehttps://www.blogger.com/profile/08077107616686254136noreply@blogger.comtag:blogger.com,1999:blog-1850379426161011153.post-80543053552973807412007-11-30T05:52:00.000+02:002007-11-30T05:52:00.000+02:00You must be somewhat naive if you think that "aski...You must be somewhat naive if you think that "asking parents to be more active than they normally would be around their young children" is a practicable intervention, or you don't recognise an article from the BMJ Christmas issue.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1850379426161011153.post-46222761974550847992007-11-29T22:14:00.000+02:002007-11-29T22:14:00.000+02:00Thanks for that David.

Of course, the mere fact that it's plausible that activeness is heritable requires scientists to take genes into account as a possible confound.Anony Mousehttps://www.blogger.com/profile/08077107616686254136noreply@blogger.comtag:blogger.com,1999:blog-1850379426161011153.post-29363053323406798552007-11-29T21:23:00.000+02:002007-11-29T21:23:00.000+02:00And, as you well know, there's quite a bit of evid...And, as you well know, there's quite a bit of evidence of activity levels being heritable in specific ways in other species, including mice and flies. So Baik and colleagues produced D2R (Dopamine receptor) knockout mice that moved dramatically less than unmodified individuals. Kelly and colleagues produced different D2R knockout mice, that initiated dramatically fewer bouts of movement in unfamiliar environments, a difference accounting for most of <I>their</I> reduced overall movement.<BR/><BR/>Baik J H, Picetti R, Saiardi A, Thiriet G, Dierich A, Depaulis A, Le Meur M, Borrelli E.
