Does the Copernican principle confirm the visibility of the maximum of the solar radiation spectrum?

Question

Physics

Recently I came across one amazing fact: the solar spectrum has a maximum in the visible range.
And in philosophy there is such an antinomy: is the place where we live special ( anthropic principle ) or ordinary ( Copernican principle ).
Strong Anthropic Principle: "The universe must have properties that allow intelligent life to evolve." But intelligence does not mean the ability to observe. For example, dolphins are unlikely to be able to see the stars. Therefore, instead of the question of the possibility of life, one can ask the question of the possibility of observation.
Since it is strange to think that the Sun shines most brightly in the visible range, so that we can see better, it is most likely that the eyes have adapted. Consequently, the inhabitants of the planet would see another star in a different spectrum. On the other hand, ultraviolet, for example, destroys proteins and nucleic acids.

Answer 1

Under conditions of competitive selection, it is logical to assume that organisms have adapted to receive the maximum energy benefit from solar radiation.
However, one of the first could be chemoautotrophs. They recover CO2 from methane using molecular hydrogen. Due to the fact that the cycle is not closed, there is a threat of accumulation of methane in the atmosphere and the greenhouse effect is obtained. However, the limitation of the distribution of methanogens is associated with a lack of molecular hydrogen.
They competed with the ancestors of green and cyanobacteria, capable of assimilating the energy of sunlight.
As for "sight," it gave the same free-floating bacteria benefits, allowing them to sense light and move through the layers of the ocean while avoiding ultraviolet maxima.
Life has adapted to its place of origin, if that is the question. For more details, see A. Markov in the book "The Birth of Complexity"
It is not entirely clear about dolphins - the ancestors of cetaceans were land animals that occupied a more convenient ecological niche for themselves.
