"so i guess to what extent is this true among snake species? and, further, is “accentuating nature” i.e. producing natural rarities the same as “preserving nature” i.e. preserving the natural/normal beauty of nature?"
Anomalies in nature like albinism, patternless and whatever else typically equate to failures when compared to the "norm" within their species. Millions of years of evolution allowed animals to change and adapt to succeed.
"Producing natural rarities" in this sense, is producing animals that would more than likely struggle or fail in nature so it isn't preserving "the natural/normal beauty of nature".
It is actually producing unnatural/abnormal animals. Beauty is completely subjective in this case.
What is true among snake species is success due to adaptation.
