I like the way Carl Sagan described how organisms store information in Cosmos. We store all of our vital information in our DNA (i.e. how to metabolize proteins etc). What we couldn't fit in there we stored in our brains, passed on through rearing children, word of mouth and shared culture. That eventually lead to the written word and now the internet. He articulates it a lot better than I do.
