Evolution of the Eye
One of the largest challenges to Darwin's theory of evolution is the eyeball.
The concept produces a challenging question:
-The first organisms could not possibly have known that there was anything to "see". Where could an eyeball have come from?
Some have suggested that eyes evolved from light sensitive "spots", but this itself poses some questions.
-Why would a light sensitive spot have been necessary??
-What would necessitate the need for such a spot??
Please feel free to post your ideas.
