Oysters and Evolution
Should we feel sorry for evolutionists? Things that they put their faith in as "evidence", things that have been considered "facts", get dropped on the dusty trail of learning. But then, they accept many things presented without question. "The oyster's twist shows evolution", but this is done with assertion and conjecture, not with plausible models. One thing I keep trying to tell Christians and creationists is that our faith is not based on the ever-changing whims of man-made science philosophies (it's like trying to patch the sinking ship of evolutionary dogmas with more unfounded assertions). Science and evidence support our faith, but they do not make it.
Oysters have the unfortunate distinction that they were one of the first examples of an alleged proof of evolutionary lineage in the fossil record (mooted by paleontologist A.E. Trueman in 1922).1 The ‘flat’ oyster, Ostrea sp., was said to have evolved into the coiled shell Gryphaea sp. Several generations of science students were taught this as ‘one of the best documented cases of evolution’ in the fossil record.To read the rest of this pearl of wisdom, click on "Evolution’s oyster twist".
However, today it seems that coiling is a built-in programming response to the environment, i.e. mud-sticking oysters grow into a coiled cup-shaped form, while oysters attaching to firmer substrate2 grow to be ‘flat, fan-shaped recliners’.3 So, coiling is an individual growth response to local environment; not a millions-of-years evolutionary twist.
