@Quehoniaomath,
Quote: Something more is needed—a mechanism. In the case of Corvettes, the mechanism (human manufacturing) can be directly observed; but in a succession of fossils, it cannot. This is where Darwin's theory comes in. For Darwin, the mechanism is descent with modification.
Oh , a takeoff on Paleys clock on the heath
The only reason Quahogs Creationist friends believe that biology is like a mechanism of a corvettes "descent" Is because they NEED IT TO BE SO. EVidence doesn't support intervention of a designer. In fact , a design "influence" is conferred by species that produce a sizable number of offspring so that phenotypic modifications are minimally available to adapt and absorb that environmental change.
Phil Johnson is the same Johnson who allowed the conjoined term of Creationism.Intelligent design to remain in "Of Pandas And People" which was a self pubished Creationist argument for biology based upon Genesis and which is bought hook line and sinker by the Quahogs.
Evolution is visible every day. Macro evolution does, of course happen in generations but examples of it, like the growing fossil record, are showing up in lab and field.
The story of the Menhaden (an anadromous fish) of the Connecticut River is getting interesting. Dams on the Connecticut river were built in the early 1700's to power grain mills and early fulling mills. Some menhaden were trapped behind the dams and the founer populations were not allowed to get back to the Atlantic after breeding. The resulting generatuions of Landlocked menhaden have developed beyond the species level and have resulted in size and shape differentiated "New" species. The most interesting thing is the development of "Gill rakers" like Baleen for straining algae and copepods from the fresh water of the Connecticut River.
In less than 350 years we are seeing actual speciation (mqcrovolution) visible with these trapped menhaden. The studies go on but , like the Finches of the Galapogos that the ornithologists from Princeton have been studying for the last 50 years, we can see speciation and evolution in our lifetimes or at least in historical time.
Most Creationists will deny all this but as the data from the above, as well as that of Mammoth v Carlsbad cave fish, isolated wolves of , Allegheny Cave rats, Kaibab Squirrels etc all show, evolution is real and denial of it is really dumb religion an science.
