Everything I sense, think, recollect, expect, say and do is remembered, including alterations of prior remembrance, as Manlobbi has so eloquently explained. Dynamic remembrance and situational recollection are both autonomic; remembrance much as Manlobbi has suggested, recollection as perhaps the most obvious example of environmentally induced decoherence.

Without the hard-wired drive to survive, our species would have ended very quickly.

Agreed that present existence is conditioned by evolution. I'd add that evolution includes every aspect of present experience, including dynamic remembrance and situational recollection, both subliminal. And we now know that the genetic code is subject to alteration by lifelong epigenetic evolution.

I may have no free will, but I can't really detect that. It seems I am making choices ...

As best I can tell, we're all alike in that.

... every day is a new day (some filled with unanticipated surprises), and I go through them without a thought about free will. For me the subject is purely academic. It's an interesting exercise, and occasionally someone has a new angle on it.

The notion of free will has garnered attention for millennia. I doubt many lose sleep over it, as it's self-evident to most, and to those who deny it it's obviously a waste of time — no problem as long as it seems I am making choices.
