I would say no finality: simply casual "byproducts" of evolution... pure fortuity...

Maybe...or maybe not. I don't know the answer to this but I know that whenever people fail to understand or explain anything they tend to say it's either irrelevant, coincidence or has no purpose, like the apendix in our bodies (which function was actually recently discovered). However, this of course doesn't mean they are right and I wouldn't approach anything unknown with such certainty.Ruggero Morimando wrote:And what the finality of its fluorescence if fluorescence is visible only at night if you have a Uv light?
We do have UV light everywhere around us all the time, we humans just can't see it (as well as other lengths of light) without equipment. However, there are a lot of creatures that do, so let's not jump to conclusions. By the same logic one might ask what's the use of pheromones since we humans can't or have lost the ability to detect them?
So Berislav is right to be sarcastic about this rather "religious" approach to live in which everything should serve a purpose to humans, or at least one that they understand.
