There’s another form of modular variation with e.g. eating than just modularly varying foods in the environment, namely: we don’t eat all the time. Instead we have some periods where we eat and other periods where we do other stuff. I wonder if this also contributes to modularity, e.g. it makes it necessary for it to be possible to “activate” and “deactivate” an eating mode while the rest of the body just does whatever.
