Vision and Evolution (A Critique of Dawkins)

[John 6IX Breezy]

At work.

Why wouldn't it? If you know anything about vision, or followed the discussion, you would know that the two go hand in hand. If anything my OP is criticising those who look at the eye without looking at things such as consciousness. So thanks for the demonstration.

Hello Mr Breezy!

Thank you for your reply.

Currently doing my best to keep up with the thread.

Soo.... what then do you say of organisms that have eyes but do not have neurons, so no brains and hence probably no discernable consciousness?

Cheers.

I would ask to see what specific organism you have in mind to better answer that question. But most of the time, organisms have some other way of making use of that sensory information. In bacteria the energy produced by light sensitive pigments goes straight into powering their flagella for example. In my view, such a bacteria has successfully evolved a functional system, that works for its needs in its environment. It has no eye, no brain, etc. So clearly, organisms can find pockets where sensation, perception, and behavior, are all balanced at any given stage of evolution. There are many such pockets inhabited by many different species. My issue is with accounts that ignore the balance between components that are needed for survival. when they talk about how an organism evolved.

Different species have different biological needs to survive in their environment. Our species needs neurons and consciousness, take that away in any increment you want, and the medical literature is full of examples of what happens.
