Can you define "changes" without reference to time?


My dog cannot tell time but knows when to eat by the
changes in her feelings from not hungry to hungry. Time
is just an artifact of man's mental model of reality.
Before man emerged, living organisms got by on changes
alone with no reference to time.

I think bats existed before man. They seem to have pretty good
perception of time.
