For every action, there is an equal and opposite reaction.
Keep it going Dark Knight. I'm enjoying your reponses to the guitar man and Dimensio. You got them on the run. However, they haven't thrown in the "strawman" and "non sequitur" at you yet but I'm sure its coming.
Evolution doesn't happen in 100 years - it happens after hundreds of thousands of years.
Look at the Toucan with it's huge beak. That large beak evolved because of the bird's food supply. The same thing is happening with these finches. After several hundred thousand years of beak size changes, it is very likely that you will end up with an different species.
Here's how it happened with the Toucan - if the seeds the bird eats keep getting bigger, then the baby birds born with larger beaks will get more to eat. Since they get more to eat, they will be more likely to reproduce. Some of their babies will be born with even bigger beaks, those babies will get the lions share of food and the tendency to have babies with larger beaks will continue. If the smaller-beaked babies don't get as much food (because their smaller beaks can't deal with the larger seeds), the smaller beaked birds will tend to not have as many successful offspring, while the larger-beaked birds will. After thousands of generations you end up with birds with huge beaks. After a few more thousand generations, these large beaked birds are no longer the same bird as their smaller-beaked distant relatives.
This is how evolution works.
It's you anti-evolution crowd that keeps changing the definition of "evolution". Every time a discovery comes along that points to the existence of evoluton - the creationists will decide that evolution REALLY means something else.
Evolution means just what Darwin defined it as - the survival of the fittest. If the smaller beaked finches are "fitter" then they will survive better than their larger beaked relatives. Check back with them in 300,000 years and they will have become a whole new species.
I haven't "changed" the definition of evolution one whit.
LOL
It is somewhat ambiguous at borders, because of the nature of speciation
That is circular logic at its finest.
Are you going to support your previous unsubstantiated assertion that the rebuttal to Ann Coulter's claims that I referenced are "garbage", or are you going to continue changing the subject every time you are asked to provide evidence for a claim?
Please explain how the fuzziness of species barriers poses a problem for the theory of evolution. Be specific.<<
You don't know what a species is. That is one of the reasons there are crappy results for ToEs.
>>It is a fact that alelle frequencies change over time. The explanation for the process that causes such shifts in alelle frequencies is theory. Your statement is demonstratably false<<
If evolution is both a theory and a fact...biologists have been giving the public crap for years.
Pick either a phenomena or a theory. But don't claim both.
Your statement is methodological crap.
>> Please explain why genetic algorithms, which produce useful and efficient circuit designs, are "fringy".<<
Gee, the underpining theory of all biology can produce some minorly useful "circuit design" when I cited MAJOR advances that will help humanity in incredible ways.
Gee. Sounds kind of fringy to me.
>>You have made a claim that is hinged upon your knowledge of the subject. If you cannot demonstrate adequate knowledge of the subject, then your claim is questionable.<<
Look in a mirror. ToEs have not proved their usefulness. Obscure circuits vs man machine interfaces. You just don't get it.
Your claim is questionable. Biology is doing wonderful things. ToEs aren't
I look forward to the wonderful things biology has to offer.
ToEs just aren't that important.
Thanks

The existence of advances that do not rely on evolution does not negate the existence of advances brought about from the theory of evolution.<<
Still don't get it. ToEs have not brought any real advances in science. They are still in the thought experiment stage.
Obscure circuit design is the best it can do?
That is because it has "crappy definitions" (like species) or silly definitions like natural selection or random mutation aren't well defined.
But when you get results, I'll look at it again.
Crappy science, crappy results.
DK
What is a species?
I know the definitions. You will crap out on this one.
Explanations without bound...you have not produced results.
You would be fired in the private sector...just like Ghost Busters.
>>The existence of advances that do not rely on evolution does not negate the existence of advances brought about from the theory of evolution.<<
What advances?
That is what I've been asking for for decades.
DK
I'm excited as heck that someone figured out how to send a single strand of DNA through a microchannel and sequence the DNA
I'm excited as heck that someone may be able insert DNA into a correct place using carbon nanotubes.
I'm excited as heck someone found a compound the body does not reject and appears to be able to build prothetics that can interface with the host.
I'm excited as heck that someone figured out how to use stem cells to coax damaged spinal cords to grow into functional stuff
What if you found out that all of these someones were also evil-utionists?
What if you found out that all of these someones were also evil-utionists?<<
Since their discoveries were neutral to evolution...like most discoveries...
Don't care.
DK
LOL
You know, DK, you may be right. Maybe all this evolution stuff is just fiction. So tell me, what's the alternative explanation for the variety of life on Earth?
