Random chance is one of many mutations. The selection isn't random but depends on who is better at reproducing and is thus extremely dependent on environment. The gecko that isn't eaten and lives long can reproduce more often and if its offspring lives in close neighborhood with one that is more visible the more easily visible will be eaten first.
Even if there is seeming evidence for design in somethings, I would still be left wondering how some design is so bad and usually only just good enough. A sentient being that could design one thing like salamanders that can regrow limbs or livers that can regenerate, simply forgets to add the same healing capabilities elsewhere. I would have to conclude that is a rather incapable being or erratic one. The god that is usually claimed to be responsible for theists seems less likely than the flying spaghetti monster. Evolution explains the distribution of those differences, design would leave you wondering about the sanity of the designer, guided evolution would leave me wondering if that what we humans are now is really the end game.
yeah im stumped, thats great.
its probably due to complexity, size and energy cost in terms of limbs.
regenerating livers (or any organs ) would have changed the world. i know they are important.
but at the same time most life is more resilient than one would think..except for the obvious built in obsolescent.
...but
regenerating livers are probably a byproduct of diet or toxin exposure.
so technically the children of alcoholics should turn into klingons in the future.
but not really because they have personal choice in alcohol exposure.
but in a drinking society, sooner or later liver problems will decrease right? evolution.
and then you have to hope that those individuals with better liver genes reproduce.
and then the rest probably die out.
so only alcoholics are left.
and those that did not drink in the first place..
who are now the lesser species.
fantastic.
anyway thats quite random but in terms of a god creating erratically, the worst case scenario is that evolution is a natural process and god has plenty of time on his hands.
sure maybe he pushes in certain directions every now and then but its almost always against the grain.
as a thiest.. muslim in particular. imo humans are not the end game.
i mean angels are made of light and we dont even do holograms yet.
a recent trend i have observed is a lot of people heading towards determinism in term of world theory. so i guess its almost guided evolution but without the god bit.
in those articles i posted the thing that got me was that a clam can disguise itself as a fish?
how does anything get that specific and the prey does not change?
it may be evolution but it is so highly dependent on so many factors that it seems improbable.
i have no idea but imo.
but yes regenerating limbs and organs would be brilliant.. evolution would take even longer to happen.
i just thought of something that id like to share,
in terms of human evolution there is something known as beta thalassemia trait.
its an abnormality of red blood cell shape.
i dont know if it can account for lazyness due to iron deficiency but the trade of is that people with it cannot get malaria.
so being at a disadvantage genetically is actually of advantage in that instance?
strange how things work sometimes.
...but i dont know how that would effect the next generation and so on.
in the long term it would become disadvantageous because it no longer becomes a trait but actual b-thalassemia.
so evolution is probably more complicated...and less likely than it would first seem.
