A paper in PNAS mentions the word evolution 15 times, but the evidence for
it is completely lacking.
Here is how it goes:
“Behavioral data show that the red pigment attracts diurnal geckos, the
likely pollinator of one of these plants.”
“These findings join a growing list of examples of
distinct biochemical and molecular mechanisms underlying evolutionary
convergence and provide a fascinating system for testing how interactions
across species drive the evolution of novel pigments in an understudied
context.”
So that what it had to do with evolution.
