"Ring Species: Unusual Demonstrations of Speciation" by Darren E. Irwin, Ph.D.
The striking article above is from ActionBioscience, considered by Scientific American to be of the best science sites on the internet.
Over and over we hear that Evolutionary science is crumbling. This is hyped and dishonest propaganda from the religious right.
Intelligent Design theory and creation science are not science because nothing they claim can be put to experiment for hypothesis verification, a prime element in the scientific method.
ID is not science because scientific ideas can predict. ID can not predict anything because it has no set of principles that hold true and can be observed in nature. The baloney of "irreducible complexity" is not a supportable scientific concept and is rejected by the vast majority of scientists as bunk. Pundits of this term can not even define it in scientific terms that can be verified.
On the other hand, evolutionary science predicts that speciation due to environmental pressures will give us changes in species that move to different environs. These species are the diamonds of natural selection which can be observed in nature in Ring Species (Explored in the above link). It is exactly what evolutionary science predicts and it is exactly what is observed. Our species' history, due to several branches of science is seen in the same way, with slow speciation until one branch becomes so different that it can no longer interbreed with its ring neighbors. The Ring Species of the article strongly confirm evolutionary ideas. The observation of Ring species verifies basic evolutionary theory. ID and creationism predict nothing and has no science to base any prediction on. Darwin's observations in the Galapogos Islands off the Equadorian coast is what solidified the first concepts of evolutionary science. Evolutionary science developed due to observation.
Have you ever heard of an experiment to verify "irreducible complexity"?
You haven't and you never will. Verification of ID is as promising as proving the exitence of a supreme intelligence. It is outside the realm of science because science deals with the natural wortld, not the hypothetical supernatural one. ID is philosophy and religion, not science. Science is based on a strict method of observation, hypothesis building, experiments to verify hypotheses, and models that can predict natural phenomena. ID and "creation science" can do none of that. They have no models that are scientific. They are pilosophical and religious hypotheses and are outside the boundaries of true science until they can adhere to the scientific method.
For millennia, due to the ignorance and neurologically wired superstitious nature of humanity, we have always invented supernatural beings when we can't grasp the complexities of nature. All the ancient religious texts evidence this understandable ignorance. We did it with thunder and lightning. We did it with floods and droughts. We did it with quakes and volcanoes. We did it with famine and pestilence. We did it with infertility and mental illness. Now, those not enlightened regarding the strict nature of the scientific method are trying to put these primitive ideas into the classrooms of our kids.
When we don't yet understand something, we still stick to the scientific method because it is the only way we will be able to explain something in tangible terminology. ID is not science.
