lol i wonder who the one is that doesnt understand it :D but this cuts do deep into other topics and has much to do with what you believe, since this is out of what we will be able to know for sure anyway (which alraedy is a completely different topic) if you discuss these things, you better start inventing something that cures death first
Evolution is a load; there's hundreds of thousands of species, each have their own unique eyes. Each eye needs hundreds of thousands of different functions to work. Then the brain which probably needs billions; in fact, the brain is so complex we don't understand how it works.
Most eyes operate on the same principles, ball of watery stuff with a lens on the front and photosensitive cells on the back, expose the cells to light and they trigger an electrical impule which goes to the brain. I've pulled fish eyes apart and they are more or less the same as human eyes.
Yeah compound eyes are different, but that's only one type of eyes and it's also prolific. Point is, animals tend to reuse components, a compound eye is a compound eye, a humanish eye is a humanish eye, aside from minor differences in size, shape, and what receptor cells are present.
true that ... ofc, whatever doesnt work dies out - thats evolution - survival of those who adapted to their habitat best. the adaption though is pretty random - thats what rex meant to say - evolution doesnt follow a masterplan. well at least thats how i see it at least, and thats what i meant with it goes into believes. ofc "god" could have set a big masterplan aswell, it wouldnt make the slightest difference in how we percieve it :D
When science can tell me exactly how the human body works (I mean every intrinsic detail), then come back.
I can say with relative certainty that nothing you know is exactly true, simple weight of probability supports that, there are so many ways it can be even slightly untrue that the chance of you getting it exactly right is so small as to be infinitesimal. So I hope you aren't making any decisions or doing any reasoning at the moment because if you are that averse to doing things wrong your head might explode.
when the manual of my new laptop explains exactly how transistors and electricity works, i will start believing the manual is correct on all the other "broader" things like where the "turn on" button is edit, fuck it, evolution thread here i come
Evolution and the origine of the species debate do it here i added in most evolution debate posts from the other thread to this one
Here: http://www.expasy.ch/cgi-bin/show_thumbnails.pl http://www.expasy.ch/cgi-bin/show_thumbnails.pl?2 We know a lot more then you think we do. But what we know is still a single drop in an ocean of knowledge... Edit: also rofl at thread mitosis that is awesome. Second Edit: there is a whole fricking huge poster of the metabolism it is about 2m^2 big. This is a part of it, which is just 0,04m^2: This one times 50 gives you a pretty good picture how life works.
What we currently do not know if the specifics of gene allocation. That is, how genes are expressed in different cells. Beginning with the human genome project, the results were a lot shorter than we expected. This meant that there had to be another factor determining how genes are expressed other than strictly DNA. Also the brain is still largely unknown.
