I was amusing myself on the bus by thinking more about a theory of packaging evolution.
I have jumped straight to my conclusion
Packaging evolves by weight reduction
Very topical
But is this a purposive, a teleological theory? Or is it the survival of the most lightweight?
If I were to launch an empirical investigation, would I first need to develop a taxonomy of packaging?
Can a tin can evolve into a plastic container?
Which led me to a question I had not thought of before. Did Darwin take the existence of species for granted?
