Re: Why do we eat what we eat?

Energy.

Living organisms gather energy within themselves in the form of biomass. At some point they realised they could steal these large reserves of energy from others, instead of slowly building up their own from sunlight and thermal vents.

This created a food chain, which prompted the evolution of larger and more capable creatures.
