RE: Proving Evolution
Evolution doesn't favor any particular trait. I often like to say that angiosperms and gymnosperms (plants) are as impressively evolved as humans. They have existed for millions of years, live for centuries, are some of the only if not the only large body producers in any ecosystem and have through years of reproduction changed the chemical composition of the atmosphere of the planet for good.
I would say no, but it really depends on what you consider veridical perception. If you consider it's fundamentals and really just call it spacial perception of some form, then evolution does not favor it, but it IS often observed as an attribute that allows organisms to continue their lineage, beating out similar organisms performing without any veridical perception.
