I suspect almost all creatures are more sensitive to motion than to anything else in their world. I have no doubt that motion triggers meaning for almost all creatures as automatically as fear triggers meaning that results in the reaction of fight or flight.

Hey I was where you are a couple of years ago collecting fish for a population study of sorts. I was in a river that flowed toward the Mississippi instead of the east coast, one of the few to do so in NC.

So about time, it's about time? I read your post and I am still a little bit confused. Are you saying that time is a human concept that doesn't exist outside human perception or that humans name the concept of time to measure motion or is there a third choice?

I have to say that while the concept of time is indeed something humans use to measure movement. Time none the less exists outside of human perception. The decay of radioactive elements mark time and we were not aware of them when we first started measuring time.
