Speaking of misconceptions.
You seem to be equating "early man" with the Neanderthals and cro magnon and these being closer to the "apes". For example you comments on longer arms and smaller brains.
You need to learn a lot more about other homonids and those that preceeded them. Neanderthal and cro-magnon are not "early" in our evolutionary history at all! They are the very, very last steps to fully modern humans and were very close to us. So of course they have human like brains (cromagnon was, in fact, "us" ) and anatomy.
Your whole post about misconceptions seems to be a misconception itself.
