I honestly don't have the time to look up specific studies that I can link on here, but I could list some examples, including macroevolutionary experiments (one about behavior comes to mind.).JohnStOnge wrote:Could you provide some examples of some of the experiments in which predictions based on evolutionary theory have been made and the predictions came through. I have looked for experiments like that before and have seen stuff like the document at http://www.icts.res.in/media/uploads/Ta ... Rainey.pdf" onclick="window.open(this.href);return false;. It talks about the evolution of populations of bacteria into groups that cooperate with each other. But, as the authors state, "Undifferentiated groups of WS are a far cry from multicellularity."How else are you going to verify something other than through observation? There have been multiple experiments, both in the lab, and outside in the wild at which they have made predictions and those predictions came through.
What part of evolution is not an established fact and doesn't pass the test of scientific fact? You're being extremely vague and without examples to support your position I can't really acknowledge your argument. I believe you've brought up how it hasn't been proven how cells turn into multi-cellular organism, but that doesn't invalidate the established facts of evolution theory.
What they describe is a phenomenon that is consistent with a process that could lead to the transition into multicellularity. But the transition has not been experimentally achieved.
With the germ theory, experimental documentation of the basic point (pathogens cause disease) is copious. The proposition of the idea that pathogens cause disease is much more thoroughly supported by experimental evidence than the proposition that populations of single celled organisms can transition into populationis of multicellular organisms is. And the propositioni that such transitions can occur is critical to the overal theory of evolution. It's a cornerstone.
On the question of how one can verify something other than by observation: There are two types of studies; observational and experimental. Both involve making observations. But what's known as "observational" study usually cannot be used to infer cause and effect. And I use the term "usually" only because if you see something like a diesel truck hitting a dog and the dog dies from being splattered you don't need an experiment to tell you that getting hit by the truck killed the dog. The actual rule is that observational studies can't be used to infer cause and effect.
Experiments generate observations but the observations are associated with experimental control and design. They can be used in all instances to infer cause and effect.
But the problem I have with what you are saying here is basically that evolution isn't a "fact" because we don't know how single cellular organisms turned into multicellular organisms.
That's like saying gravitational theory is wrong because we don't know the gravitational pattern of one particular star.
Just because I can't link you a study does not mean that there isn't an explanation. Regardless of whether or not I, as a non-expert, can provide you an explanation, or if there is one at all, does not invalidate the facts of evolution. I'm more than willing to bet that there is actually an explanation, I just can't find one that I have read through (here's one?http://www.ncbi.nlm.nih.gov/books/NBK28332/ )
Another better question would be, if not by natural processes, how else would cells become multicellular? Evolution deals with the diversity of life, and as stated multiple times, I may not have an explanation as to how unicellular to multicellular specifically happen, but whatever scientific explanation we find, that won't invalidate the current facts about evolution.
You saying evolution isn't a fact because we haven't observed unicellular organisms evolve into multicellular organisms (which is a claim I am skeptical of in the first place) is the equivalent of saying the big bang isn't a scientific fact. We can't and haven't observed anything like the big bang happening or experimented with it either, but scientifically it is still considered a fact. I'd actually make the argument that the particular evolution we are talking about could be easier proven than the big bang in this circumstance, as at least we have a chance of observing and testing it in the future.
Honestly dude, you're not making a compelling argument other than saying "we haven't observed event A take place therefore we can't say it specifically happened" but all the evidence points to it occurring, however it occurred, and the ignorance we have towards specifics of that aspect of occurrence does not invalidate things we know for sure about evolution.
