Not I, some child, born in a marvellous year,
Will learn the trick of standing upright here.
The Economist reports on new developments in evolutionary biology, specifically the question of why our primate ancestors did learn the trick of standing upright. What was, in management-speak, the key driver going forward? Quote unquote:
Africa’s great grasslands are one of that continent’s most famous features. They are also reckoned by many to have been crucial to human evolution. This school of thought holds that people walk upright because their ancestors could thus see farther on an open plain. Forest primates do not need to be bipedal, the argument continues, because the trees limit their vision anyway.
Sarah Feakins, of the University of Southern California, says it ain’t necessarily so.
