I was watching a tv programme based on our evolution from single cells to worms to vertebretes etc.

This has got me thinking. We evolved from things that only had brains in order to process information. They developed eyes and so needed a way to sort this data. So if our purpose is curiousity then why bother with the lengthy process of evolution?

And im worried that it does make more sence that since we evolved from these creatures would it not be logical that our brains are just advanced versions of this example?
