By "we" I was referring to all organisms that detect light but do obtain
energy from it, of course.
My premise, which I admit is speculative, is that plants and animals share
a common ancestor capable of something similar to photosynthesis, probably
facilitated by beta-carotene which is a chemical precursor to both plant
chlorophyll and animal retinol.
This idea is not my own; I accepted the hypothesis as reasonable after
reading a compilation of essays by some prominent evolutionary
epistemologists. I'm sorry I don't remember exactly which philosopher was
responsible for this particular idea, or even the title of the book. At
present that book is in storage but I could try to dig it out if necessary.

Sorry, I have no idea what that means.

Sorry, I have no idea what that means, either.
