My point being that how does one object change over time? How does a cell start displaying new characteristics? Also you didn't explain Bee's and Flowers became co-Dependant. Theres no doubt they are and they adapted to befit each other. But even with millions of years(time aside) What causes two things that are unlike to work together. Its not like one day the Bee got up and said to the flower. You give me nector and I'll pollinate other flowers for you? How would a flower realize that a bee could carry its pollen? And according to evolution Bees/Flowers weren't always on this planet.
Also what would cause a small mutation that conveniently becomes the right adaptation for the surroundings? If things were always randomly mutating we'd have allot of worthless non-functioning creatures and don't give me the spill about natural selection. Because there would be allot of things out there that would survive but have allot of useless mutations.
i haven't read past this post, so i don't know if you have fixed it later in the thread, but you are off on quite a few things...
first off, cells start displaying new characteristics completely randomly... how do they do this? UV rays damage dna, free radicals damage genetic information, mismatching of base pairs during processing of this info etc etc, there are literally hundreds of possibilities; pair this with the virtually infinite amount of genetic information transfer from dna->rna-> protein and all the other variations, that leads to an astronomical amount of mutations..
so why don't we all have 9 arms and 3 heads? because we have mechanisms to fix these random "breaks in the chain" ie. proteosome/ubq pathways, or something as simple as a single bp replacement/correction....along with that, a HUGE percentage of our genome is nonsense (introns etc), and isn't translated into anything we need, so the mutations aren't even noticed on a phenotypical level...
every once in a while though, certain mutations make it past all of these regulatory mechanisms that we have to prevent damage to our genetic makeup... **these mutations are not derived by the organism to help them adapt to the environment though, as many people believe... they are 100% RANDOM...
it could be positive or negative, all depending on the organism, it's environment, and countless other factors...
so let's say that the mutation was "positive" (relative term), for arguments sake let's say that we had an ice age, and dsade (purely for example purposes) had a mutation that gave him a thick furry coat on his entire body... now dsade is going to survive much more easily than i would because i don't have the gene for a furry coat, and i will freeze to death... so dsade will survive, reproduce (very often since he is now the fittest of the species), and chances are, that this new gene for the furry coat (which was originally a random mutation) will show up more often in the population as we continue down the generations... eventually, over a long time period (depending on reproduction habits for whatever organism this may be), this gene will most like be dominant, since the organisms who possess it survive more easily...
now lets say some other intelligent species looks at this change in dsade's kind without any knowledge of genetics or mutations... it will appear to them that the species "adapted" to the changing climate by developing a fur coat gene and managed to survive, when really it was a random mutation that happened to benefit the species over a VERY long time period... and in this same time period, literally millions of other mutations happened in other members of dsade's species, both positive and negative, and may have helped or hindered those affected..
i don't feel like going back to make sure i didnt make any mistakes because that was a lot of typing... but when you look at it with an understanding of cell biology and plain, simple darwinism... natural selection is a perfect model for what has happened over time
dr.liftalot, as you said "If things were always randomly mutating we'd have allot of worthless non-functioning creatures ............ Because there would be allot of things out there that would survive but have allot of useless mutations."
absolutely there are... but what we tend to do is look at "higher" organisms like humans, dogs, whatever... as humans, a generation takes like 25 years, so to see progress in our species is virtually impossible... to see this process happening at an appreciable rate look at something like bacteria, who can potentially double their population in hours, even minutes... the rapid changes in genetic makeup can be seen easily
bee's and flowers becoming independent didn't happen overnight, it was most likely a painfully slow process that just happened to click over a very long time
as human beings we try to make sense of everything in a way that we can understand it easily and relate to... not everything works that way, especially evolution..
i'm sorry if i am just repeating something that someone said earlier, as i said, i only read up to the post that i quoted above before i typed all this out... i'm sure a missed a lot of points because i get side tracked easily, but i would be more than happy to explain something i skimmed over, or possibly just typed out completely backwards...
i'm not trashing religion, i'm just very knowledgable in science, especially cell biology and genomics... so everything fits together nicely for me in the science camp as of right meow...
i think anyone who doesn't understand what i posted, or couldn't believe that evolution happens the way it is explained by darwin needs to read "the origin of species"... or at least read over evolution on wikipedia, it will hopefully help you understand
