Quote:The earliest predecessors of the eye were photoreceptor proteins that sense light, found even in unicellular organisms, called "eyespots". Eyespots can only sense ambient brightness: they can distinguish light from dark, sufficient for photoperiodism and daily synchronization of circadian rhythms.How did photoperiodism and daily synchronization of circadian rhythms develop before eyespots came along?
Unfortunately a search on evolution of eyespots (the first step on the journey) mostly turns up pieces on false eyes on butterfly wings. Here's one that's on point:

Quote:Now that random mutation is understandable, imagine a population of plain, primitive bacteria (no specific size, shape, etc.). There are trillions of them scattered throughout the world. Imagine that one out of every million of these trillion bacteria experience a mutation which allows it to have a pigmented surface. That means we have one million bacteria with some kind of a light-capturing surface on them. A few out of these million bacteria develop the pigmented spot over an opaque surface connected somehow with the rest of the internal network of the cell (Patton). These few cells, have just developed a primitive type of vision.The irreducible complexity problem is just blown off with a single sentence.
I could have a light sensitive cell on my elbow, but it's not going to do me any good, as the rest of my body either doesn't receive the information it provides, or doesn't know to do anything with that information.
