When eyes were first developed in animals, suddenly animal life becomes proactive.
Although Darwin was able to persuade much of the world that a modern eye could be produced gradually from a much simpler structure, he did not even attempt to explain how the simple light sensitive spot that was his starting point actually worked.
But sequence comparisons simply can't account for the development of complex biochemical systems any more than Darwin's comparison of simple and complex eyes told him how vision worked.
Your whole life informs your eye.
But the ear, let us not forget, starts operating on the forty-fifth day of the pregnancy of a woman. Seven and a half months advance over the eye...(but) what do we do in our society, in our civilisation, to continue this process?
Ruskin's concern for art education applied to the development of the power of the hand and eye for everyone.
The common ancient ancestor of mulluses and chordates could not possibly have possessed a camera eye, so quite clearly they have evolved independently. The solution has been arrived at by completely different routes.
