i believe in mutation, and the fact that the environment changes and we happen to mutate( in a beneficial way) when something happens that could harm us, sometimes leads me to believe that the the environment adapts to the species, not vice versa....AHHHHHHHHHH

but that makes no sense... dont organisms evolve an become more complex, ive never heard of anything going from being complex to the point where we cant figure things out, to being something more primitive

I dont believe in divine intervention... How could evolution make a species change from something as a fish to a mouse, would that disprove darwins theory? i think not, because we (humans) are very similar to monkeys in the way we are classified, (i do not know if we "evolved" from monkeys, i know there are other theories of evolution but i haven't read into them very much) but i doubt an act of god is what is changing things on earth

if my *offspring* and I waved our arms around our entire life, *down the road my children* would have deformaties... you mean my wife right, not my children

According to the "theory of natural selection" changes occur randomly in a population, so by this, could they be saying that mutations occur randomly or evolution.. idk if im making any sense whatsoever, thats y i debate whether or not they are the same

so there is a difference, evolution is based off mutations

i forgot to take into consideration that, mutations are usually not beneficial, but still, could evolution be a type of mutation?

I would like to add something that hads been puzzling me for quite some time now, Is there a difference between evolution and mutation? Evolution is a change that is supposed to be beneficial to that certain organism to adapt, but happens over a long period of time, and a mutation is a sudden random change of the DNA structure causing physical/mental changes, i was debating on whether or not evolution and mutation were the same, ill tell you why this came to mind- In class we talked about the "Theory of Use and Disuse" which is obviously an absurd theory (in my point of view), the theory was- If an organism constantly uses a trait, that trait becomes more developed, also the acquired trait "can" be passed on to offspring- Ex: A giraffe spends its life stretching its neck and its neck becomes longer,thus meaning that its offspring will be born with a long neck...WRONG I was talkin to my teacher about this situation, shes said that in Africa there was a point in time when giraffes had short necks, then a mutation happened causing them to have long necks. (bear with me please) But... at the same time as the mutation occured there were no leaves for the giraffes with the short necks to eat ( there were only leaves on the high parts of the trees) Now, a mutation that happened to the giraffes while the leaves on the lower parts of the trees were gone couldn't be a coincidence, (I brought this up w/ my teacher and she didnt reply) so the giraffes w/ short necks died out because they couldn't reach the leaves, leaving the long necks giraffes. I dont know how it came to be that giraffes acquired long necks right at the same time as the leaves being gone... i dont know if this makes any sense, but i don't think it is just a coincidence. this is what brought me into this state of confusion

thanks

u say light can be slowed down in a different medium... what about when light comes in contact with clouds, would that be a medium where light could be slowed down?
