You seem like you know a lot more about this topic than I do lol. I’ve updated my comment to some important context I should have added from the beginning. You can also dig through this thread to see more in depth explanations of lacking context.
The sun is a greenish star and what I was getting at was that a large portion of the Sun’s emitted energy is in the form of green light meaning that plants can reduce the magnitude of fluctations in recieved energy by reducing their intake of green light. As you said though, you haven’t seen it definitively proven that this is the case.
As for the red a blue wavelengths of light… honestly I don’t know nearly enough about photochemistry to talk on the subject and was just parroting what the research paper reported. I am not nearly far enough into quantum to have even heard the term exciton lmao (but I did look them up and they seem cool).
Fantastic to know that plants are just magic actually. Very cool

I couldn’t find it on anna’s archive either but I also couldn’t invest too much attention rn. If you find a link could you comment it here? Im gonna keep looking as well later and will do the same

This is a comment I wrote a while ago on a post specifically about the ability of visible to evaporate water. I thought some of the info was relevant to the meme but I can see how some of it wouldn’t really fit or make sense.
As for all the things you pointed out
Highest proportion of energy from the sun that plants absorb* should have specified that and its on me.
Second point is pure speculation and conjecture and is not intended to be a statement of fact
I really recommend reading that source I linked

Plants are green specifically because the red and blue wavelengths of light are useful for breaking specific chemical bonds necessary for photosynthesis and as such are readily absorbed by the plant. The plant makes efficient use of the energy provided by only absorbing the wavelengths necessary for its processes. However, plants still absorb 90% of green light and green light holds the highest proportion of the energy radiated by the sun.
To be more clear, green light has too much energy. When plants absorb light it first enters a protein mesh containing pigments such as chlorophyll that function like an antenna or receiver for a range of wavelengths. The pigments then transfer the energy to a “reaction center” where it turns this electromagnetic energy into chemical energy (photosynthesis). This process is exceedingly efficient; almost all of the absorbed energy is converted into electrons the plants can use. However, this protein mesh antenna is not solid and is constantly moving. These movements affect how energy is absorbed and how it flows through the pigments. Think of diffraction in water. Fluctuation in the intensity of light can create noise in this process; a quick brush of shade or sudden increase of light intensity can decrease the efficiency of photosynthesis. For plants and really everything that lives, a steady input and output of energy is desirable. Not enough electrons making it to the reaction center causes energy failure while too much will cause general overcharging effects that can damage tissue. When the noise of this system fluctuates it makes it difficult for the plant to self regulate it’s energy flow and could cause the plant to kill it’s own tissue or essentially starve. So essentially, while absorbing all green light would provide the plant with more energy, it’s not capable of handling this energy so plants evolved to limit their intake of green light.
However, this is not to say that green lights ability to efficiently evaporate water is not a factor in this evolutionary development, hell it’s probable that these two things are heavily related. Green light might evaporate water so well because of some combination of its relatively high energy mixed with the size of its wavelength interacting with the hydrogen bonds between water molecules in a more efficient manner than other wavelengths of electromagnetic radiation.

- Comment on salmon 2 weeks ago:
Why?
The goals of the Salmon change when they reach mating age. Now they don’t need to survive in the ocean, they need to make sperm/eggs and survive the long trip to their birthplace. This trip is through fresh water lakes and rivers. That is a very different environment from the ocean. They will need to jump/swim up waterfalls. They will need to avoid predators, but very different ones than they faced in the ocean.At the end of their journey they will mate and die.
Because the goals and environmental pressures change so much the Salmon must also change to meet those new challenges. If they didn’t they wouldn’t be as successful in reaching their final destination and making more Salmon.
How?
Just like humans, hormones trigger biological changes. The change to fresh water also triggers changes and a countdown clock. The changes use a lot of energy, as does their trip and mating. Their body will literally consume itself to make the changes and meet the challenges it needs to so that the salmon make it home to mate.
