I've just started reading Leakey's Origins Reconsidered.
He states that the Turkana Boy died at an age of 12 and was
between 5 feet 6 and 5 feet 8 tall. He then conclude that an
adult "Turkana Man" would be above 6 feet (quite tall). I was
wondering: Couldn't it be that the species were fully grown
by the age of 12? To me it seems natural that more 'primitive'
species go through childhood and youth faster than Homo Sapiens.
