Evolutionary pressure itself doesn't generate new features, it merely selects them for propagation (in a self-propagating system). In biological organisms, the thing that generates new features are viruses (injections of genetic code into other genetic code) and the natural errors involved of replicating genetic code.
That answers the question of how pretty much every biological feature is produced and propagated, except the question of how/when/where something goes from being unconscious to conscious.

How about for bigger animals? Consciousness is a spectrum. Even humans, the pinnacle of known consciousness, can go from conscious to unconscious and back fairly easy. What's the exact instant when the sky turns from red to blue in a sunrise?
