It reports the findings from 133 cemeteries in the northern hemisphere in regards to the proportion of 5-19 year old individuals. When calibrated to period when agriculture was introduced into a specific region there seems to be a clear alignment in terms of a demographic transition toward a &ldquo;youth bulge.&rdquo; Why? A standard model of land surplus explains part of it surely. When farmers settle &ldquo;virgin land&rdquo; there is often a rapid &ldquo;catch up&rdquo; phase toward the Malthusian limit, the carrying capacity. Another possibility though is that sedentary populations did not need to space their offspring nearly as much as mobile hunter-gatherers. Whatever the details, <b>the facts remain that the data do point to a shift in the age pyramid during this period.<\/b> The author wonders as to the possible cultural implications of this. There is an <i>a priori<\/i> assumption that a young vs. old age profile in a society constrains its choices and channels its energies (e.g., think the &ldquo;baby boom&rdquo; generation in ...<img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/0004a_XhuckZXGc_s\" height=\"1\" width=\"1\" style=\"padding-left:10px; padding-right: 10px;\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/0004a_e8f9vpPCyzc\" height=\"1\" width=\"1\" style=\"padding-left:10px; padding-right: 10px;\"><\/p>","protected":false},"excerpt":{"rendered":"<p>The figure to the left is from a new paper in Science, When the World&rsquo;s Population Took Off: The Springboard of the Neolithic Demographic Transition.
