Saber Posted June 11, 2023 Share Posted June 11, 2023 (edited) Before creatures had eyes & ears like when they were @ the level of worms and these things........or before that They didnt have eyes or even any kind of simple light sensors...............how did they know that these an electro magnetic wave that can give them good and usefull Info about their environment ? So they went and developed and evolved eyes for themselves ? before they could hear anything how did they know that there is a physical air wave that also can give them Information about their surroundings ? So they went and evolved in a way to be able to sense that wave ? How did they knew they needed to sense things that they were not aware of the existence of those things ? Thanx............

StringJunky Posted June 11, 2023 Share Posted June 11, 2023 'Evolution is a blind watchmaker' is often used to describe the evolutionary process. Everything new is a complete accident and is the result of a genetic mutation. If it works it stays and if it breaks it's gone. Reproductive fecundity and pure luck in the environment determine what features persist. 1 Link to comment Share on other sites More sharing options...

pzkpfw Posted June 11, 2023 Share Posted June 11, 2023 (edited) You have evolution back to front, by missing the natural selection part. It's not at all about an organism knowing what would be useful, then developing it. It's (in a nutshell) about random mutation sometimes making something that turns out to be useful, which is kept by providing an advantage. And note that eyes and ears don't spring into the current form in one go. e.g. https://en.wikipedia.org/wiki/Evolution_of_the_eye Edited June 11, 2023 by pzkpfw Add more bold and italic and underline 2 Link to comment Share on other sites More sharing options...

It did not need to. The whole point of the theory is to explain how adaptations can arise, purely through more successful reproduction of creatures with a trait that happens to be an advantage. This is basic. You can read about it anywhere. The evolution of the eye can be traced to creatures with light-sensitive patches on their skin. Those that had them could move towards or away from the light and this would have enabled them to find more food or escape more predators, so they reproduced more and handed on the advantage to their offspring. Etc. This is how it works, not by an organism “knowing” anything. 3 Link to comment Share on other sites More sharing options...
CharonY Posted June 11, 2023 Share Posted June 11, 2023 Actually, light sensing arose way before skin was developed. The earliest organisms with light sensing capabilities and phototaxis were bacteria. 3 Link to comment Share on other sites More sharing options...

How could this 'purposeful evolution' possibly work? Does an animal think, "I need eyes" and then the animal just develops eyes and then somehow also changes it's DNA to pass on it's eyes to it's offspring? Or does the animal think, "I need eyes" so it changes it's DNA so that it's offspring will develop eyes? 1 Link to comment Share on other sites More sharing options...

Perhaps a DNA in some ovum or a spermatozoon thinks, "My host needs eyes", modifies itself, and prays to be the chosen one. Link to comment Share on other sites More sharing options...

When you want some thing you feel that you want it dont you ..For example if you were a creature who was in early stage of evolving a mouth you would feel that if you had some hard and sharp things in your mouth grabbing & holding on the food or prey would be easier If i was a creature who dwelled on the trees i would feel if i had longer arms it would be better when hanging on trees perhaps............. And how about devolution of eyes ? like in moles and in cave fish ? they loose their eyes by accident ? I think the motivation for evolution is Need and when the need is gone like the need to see in moles & in cave fish they devolve and loose their eyes ..........or like marine mammals who replaced arms & legs with flippers 9 hours ago, exchemist said: It did not need to.

You can read about it anywhere. This is how it works, not by an organism “knowing” anything. Although i dont disagree with this either..........i think these two traits work together but i strongly believe that even one electron has awareness and is capable of thinking..............let alone.............animals.......... not the type of thinking that we do.............but @ its own level of existence........... i believe that all the elements of this world know what they are doing in the subconscious level.........if you dont laugh @ me .............An Electron thats orbiting it nuclea ........in a little dust particle in the intergalactic.........space.......knows what its purpose is...................a light sensoring cell in a plankton that lived 200 million years ago.............knew what its purpose was..................
