> Maybe humans didn't originate in Africa. There are many arguments for and against. Sure, but the arguments against are in the same vein as the argument that, if I draw a circle, it's not a real circle, because I don't have the level of fine control over my hand that would be necessary to produce one of those, and the tip of my pen is too wide. True, but not really relevant to anything, and in particular unlikely to convince anyone that it's a mistake to call what I drew "a circle".
