So, did they do brain-scans of "teens" and "adults" in societies where the distinction doesn't exist? Seems like the critical piece missing from the argument.

It's also possible that there was a smaller difference in the brain a few hundred years ago from factors like food availability. The current over-abundance of food is changing the the timing of puberty for example.

Is it food availability, do you have a citation - I hypothesised that this was due to the wash of oestrogen-like chemicals and hormone disruptors in domestic use in the more developed nations. Edit: an example citation - http://www.telegraph.co.uk/earth/earthcomment/geoffrey-lean/6418553/Why-boys-are-turning-into-girls.html http://www.telegraph.co.uk/earth/earthcomment/geoffrey-lean/...; other articles note the increase in the use of soya in countless processed foods and the high levels of oestrogenic chemicals it has.

But in the context of this discussion, culture shouldn't be the only culprit.
