This is the first time I ask anything on this forum.
Does anyone know what the precise meaning of "biological role" is?
I recently was told that "performance" is the "ability to carry out a biological role". So what is a biological role then?
Can things like "biting" or "walking" be a biological role? Or is that a "performance"?
If these kind of things are "performances" then what are the "biological roles" that they are carrying out?
