The answer provided by @user287279 to When does a human baby develop a consciousness? is a great answer in my mind which scrapes the surface of what consciousness consists of.

When you look at consciousness and how there are different levels to it, I couldn't initially think of any lower level of consciousness other than described in the answer:

the ability to sense the world around you in an independent way

But there is the preconscious, where information is available for cognitive processing, but lies outside conscious awareness.

Dehaene, et al. (2006) provides a good rundown on the difference between conscious, preconscious and subliminal processing, along with possible reasons why some knowledge remains permanently inaccessible; however, it doesn't indicate when preconscious processing begins.

I wonder if there is any scientific argument where it is considered that preconsciousness could have started earlier than consciousness?
