I understand that all animals have their own unique abilities but it seems we have developed a brain with a capacity that is far greater then our needs. So in terms of evolution, why did it develop greater capabilities then we actually need to survive?
Why would excess be evidence of design? The human brain is obviously an organic development not a designed system, with newer layers over the top of older ones the way the Neocortex is a 2 inch layer of development over the R-Complex or "reptilian brain".
