Eyes built for blushing?
One of those "Something you should know" segments on radio just now. Claims that the spectral sensitivity of human color vision "evolved" to match the colors of blushing, so we could detect emotions in others.
Seems unlikely to begin with. Color vision serves a WHOLE BUNCH of purposes, most of which are more important for survival. Even if we take this assumption as true, it leaves the converse unanswered as usual.
If our vision was shaped "gradually" and "randomly" to detect the PRE-EXISTING action of blushing, why did blushing develop? Altering circulation in the face makes no sense as part of an emotional response unless our friends and enemies can detect it.
Advocates of "evolution" always leave these converse questions unanswered.
With a few scattered exceptions, every output matches an input and every input matches an output. You can't assume that one side "evolved" first and then the other side "evolved" to match. Doesn't matter if you assume input or output came first. There's no point in having auditory perception tuned for vowel formants if our speech doesn't produce those formants. There's no point in speaking if our friends and enemies can't understand it.
Only one conclusion is possible. The whole setup was designed all at once.
