Richard Dawkins: Halibut Evolution

Richard DawkinsI came across this video not to long ago. It’s pretty short but it gives you a little science lesson on the evolution of the Halibut (or the Flatfish). Interesting stuff.

Taken from the Wikipedia article on the Halibut

When the Halibut is born the eyes are on both sides of its head so it has to swim like a salmon. After about 6 months one eye will migrate to the other side of its head, making it look more like the flounder . This happens at the same time that the stationary eyed side begins to develop a blackish-grey pigment while the other side remains white. This disguises a halibut from above (blending with the ocean floor) and from below (blending into the light from the sky).

    The hard part here is the fact that for some reason evolution and creationism need to be exclusive of one another…

    Perhaps the halibut was created to evolve?

    Or perhaps the halibut evolved to give the illusion that it was created via “intelligent design” :wink:

    It’s a vicious paradox indeed!

    The flat fish will under go the process in its lifetime. This is not the type of evolution you would expect if it had evolved.It changes to meet certain conditions but uses the same dna not new dna.This shows a plan resembling intelligence.It happens fast and as a result refutes or makes mute evolution. If one creature evolves while it is still alive, it no longer needs the millions of years to change, making it successful. Slow change would make it volunerable to other forces that change faster.In millions of years the earth would change drastically.When I was young I saw the halibut, but, reasoned my way thru it. Evolution is not reasonable.

    That is an interesting point you make TJ.

    picktj - another retard desided to spam the internet. yes, evolution ONLY makes species that doesn’t change during their lifcycle… it’s in the evolution bib.. oh shit, evolution doesn’t have a bible. EVOLUTION means ANY change that fits/is good enough will prevail. take the damn tadpoles. the cycle of a frog is not perfect but it is successful enough in this environment so it remains. if u change the environment frogs might remain but they might disappear. the faster u change the environment the lower is the percentage of possibility of the species remaining. i guess thats too complex, but anyway… homo sapiens changes the world, we hve destoried 1/3 worlds frog species so far. gods plan? sure, ‘coz god just hates them froggies. there r MILLIONS of species like this. damn - we r in womb with hairy body and tail and we lose them before we emerge. y? coz we don’t use them but they r also not in the way in the womb. this is pointless… one thing that is genetically/evolutionaly favored is singlemindedness and stubborness (because it makes us stick with something and statistically it’s the right thing to do) and religious people are the perversion of that…
