   Lots & lots of assumptions here...   
      
   The oldest so called "Chimp" fossils are only about half a million   
   years old. They're more than 2 million years younger than Homo habilis,   
   close to 1.5 million years younger than erectus.   
      
   Oh. And those fossils are teeth. That's it. and teeth are far from   
   definitive. Meaning, they're not necessarily Chimps. It's not 100%   
   certain.   
      
   They're also in the wrong place but, pardon something of a pun, let's   
   not go there...   
      
   The human brain needs DHA. This is some of the best confirmation   
   evidence for Aquatic Ape Theory. You can't just wish yourself a   
   bigger brain, you need the building blocks and in our case what we   
   need is DHA. Now humans CAN synthesize DHA but we suck at it. We're   
   not good at it at all, men WORSE than women. And as bad as we are   
   at it we're only this good -- which is sucky -- because of a mutation   
   that the molecular dating freaks place at less than 100k years.   
      
   So where did our DHA come from?   
      
   HINT:  Seafood.   
      
   Oh that's not a hint, btw, that's the answer itself. Even seafood low   
   in DHA has actual DHA while terrestrial sources get you... what? ALA?   
      
   So the very first thing you need to grow a Chimp's brain into that of   
   a human would be sources of DHA. From there, wait out some mutations   
   that allow them to take advantage of these DHA sources, using them to   
   grow bigger and smarter brains.   
      
   That's how humans did it.   
      
   And, yes, Chimps do have an Aquatic Ape ancestor. We share a common   
   ancestor, that ancestor had a larger brain than Chimps, stood upright   
   and probably used tools in a way that people only pretend that Chimps   
   do. And after they pushed inland, adapted to the forest, lost their   
   DHA sources.... yeah, their brains shrunk.
