Evolution has built our brain in much the same way. Of course, evolution has no will, no plan. Evolution didn’t decide to give you memory for where you put things. Your place memory system came about gradually, through the processes of descent with modification and natural selection, and it evolved separately from your memory for facts and figures. The two systems might come to work together through further evolutionary processes, but they are not necessarily going to do so, and in some cases, they may be in conflict with each other.
