« Not the same ... ( 21 hours ago by XGralgrathor)
« Not the same algae we have now. » Unless they're algae with time machines. Might just happen, you know - one moment you're studying some single celled green critter through your microscope, the next it goes all Wells on you and flashes off into the deep past. Assholes, those algae, let me tell
you.

« It's possible... » Happens all the time. And it's not just algae. You've never seen a flock of Archeopteryx DrWho past you at two centuries per second, have you? Can't trust them buggers. Not just evolving all over the place, but cheating at it too.
when you say ... ( 21 hours ago by nosson77)
when you say evolution do you mean what happened i.e. common descent or how it happened i.e. random mutation and natural selection because i am aware of data that supports the former but non that supports the latter
Really? Well I ... ( 21 hours ago by Slabbers)
Really? Well I think you can't have been looking too hard then. Here's a few pointers - e coli, italian wall lizards, nylonase. You do realize that random mutation is not the only source of the variation that natural selection operates on? There is a lot of research going on at the moment to better understand exactly how much of this variation is down to random mutation and how much other factors such as genetic drift. There's lots still to learn.
Well im newish but ... ( 20 hours ago by nosson77)
Well im newish but from what iv got so far Lamarckian evolution makes more sense to me I read the ecoli experiment on wiki but i only got evidence of change not that the change happened through random mutation and natural selection random mutation is hard to prove because how do you prove something is random (as opposed to guided - in the natural sense)
Evolution has been ... ( 13 hours ago by Seekmosttoprophesy)
Evolution has been swallowed hook line and sinker by the gullible. That proves nothing. Evolution doesn't account for anything because the variation of species is NOT from "mutations". You jump to unfounded conclusions and that is NOT science. This nonsense is SO annoying! Evolution depends on a crowd mentality of everyone falling off the deep end for lack of reason! That is the ONLY reason we are even having this discussion. Your mistake is to assume that historical accounts did not take place.
The variation of ... ( 13 hours ago by Seekmosttoprophesy)
The variation of species ("adaptation is experimentally verified") is from the preexisting design (it is not from "mutation"). The design can only vary so much before it gets warped and not viable. "Mutations", by definition, are not good because they only corrupt the original information of the preexisting design that IS good.
Because it is " ... ( 13 hours ago by Seekmosttoprophesy)
Because it is "accepted" is NOT scientific evidence or proof of anything. The ocean floor will always be on the bottom and subsequent layers will always contain other creatures. The fact there are buried creatures all over the world is evidence of the worldwide flood. The fact there are buried humans that are not directly related to us is also evidence of the flood. That fact that all of this is actually recorded in history is good enough reason to consider it.
Are you trying to ... ( 13 hours ago by Seekmosttoprophesy)
Are you trying to convince yourself or me?
Objects do NOT make information. Directives do not come from thin air. It takes proteins to make proteins. It takes preexisting information to make proteins. No matter how you give credit to objects, it is never "eloquent". It is called a belief in the power of objects which is idol worship.
Not only do you ... ( 12 hours ago by Seekmosttoprophesy)
Not only do you need proteins to make proteins, you need preexisting information to make proteins. I do not appreciate giving credit to objects for what they are not able to do. Believing things that do not happen is what is irrelevant. The variation of species is NOT a result of "mutations". The variation is from the shuffling of preexisting information that was already there. The variation is from the design itself but there is always a limit to the variation and it is always reverting back.
I laughed out loud ... ( 10 hours ago by Alpha1Bravo1Charlie1)
I laughed out loud because the religious person is calling me gullible. If it doesn't occur from mutations, what does it come from? Because as far as I know, not even the most extreme believers in creationism claim variation is species come from something other than mutations.

Wait wait wait. What does that even mean? Variation is from preexisting design? What the fuck are u talking about?
"The variation is ... ( 10 hours ago by Alpha1Bravo1Charlie1)
"The variation is from the design itself but there is always a limit to the variation and it is always reverting back." Prove it. Oh wait, you can't. Because you are absolutely 100% completely incorrect and what you're saying and have been saying are wrong and couldn't be more wrong.
I think perhaps you ... ( 4 hours ago by Slabbers)
I think perhaps you are being misled somewhat by the fact that it is impossible to prove something 100% in science. However, all the evidence shows that even if mutations are guided, then they are guided to occur in a way that looks exactly as if they were random. Random mutation is by far the best explanation: it fits the evidence perfectly and there is no testable alternative theory.
Lol seekmost, hello ... ( 4 hours ago by Slabbers)
Lol seekmost, hello again! The only thing supporting your position is the Bible. The only thing supporting evolution is 150 years of evidence and continual testing in the most rigorous and critical discipline known to man: science. No contest.
The evidence ... ( 4 hours ago by Slabbers)
The evidence contradicts you. What is the mechanism that prevents very small adaptations accumulating over time to become large adaptations? Accepting micro but not macro evolution is exactly like believing in inches but not miles.
The Bible is not ... ( 4 hours ago by Slabbers)
The Bible is not recorded history, and as that is your only evidence for a worldwide flood, and as the actual evidence contradicts you, you fail on a truly Biblical scale...
How does this ... ( 4 hours ago by Slabbers)
How does this shuffling of preexisting information occur? What is the mechanism? Is it random or does God direct it? How come the evidence contradicts you? What is you explanation for Italian wall lizards growing a cecal valve that was previously only know in different species? How do you account for the perfect sequence of morphological development shown by genetic studies and the fossil record? Why has not a single fact ever been found that contradicts evolution?

i havnt seen any evidence to support the idea of evolution from random mutation, the Italian wall lizards and the nylonase seem to me to be irrefutable evidence for controlled editing of the DNA by the organism

« i havnt seen any evidence to support the idea of evolution from random mutation » Check Richard Lenski's work. And read up on the "nylon bug". Some of the variations recorded in these studies were directly attributable to mutations.

XGralgrathor the nylon bug just shows that there are changes in the DNA not that those changes are random on the contrary it indicates that the changes are directed by the organism

when did i make a claim i said it seems to me but i think there is evidence 1) the nylon bug which evolved twice the ability to eat nylon using 2 different mechanisms 2) the Italian wall lizard evolved to quick for random mutations and natural selection
