Everyone has heard of the kangaroo and its pouch. It is a marsupial—mammals that give birth at a relatively early stage in development, and then carry their young in a pouch. There are a great variety of marsupials that are curiously similar to a cousin placental species. The flying squirrel (a placental) and the flying phalanger (a marsupial) are one such example. Because of their reproductive differences evolutionists must say they are distantly related on the evolutionary tree. Yet they have strikingly similar designs which must have been created independently by random mutations. Every mutation leading to the two different species must, according to evolution, have been random (that is, independent of any need). No, natural selection doesn’t help.
Another example is the human and squid eye designs, which are remarkably similar. Of the myriad vision designs, these two utterly different species share similar designs that must have arisen in completely different environments, on different substrates, to meet different needs. It is, as Darwin often said, utterly inexplicable.
These are but two of a large and growing list of remarkable convergences. Though evolutionists sometimes deny biological convergence, it is a scientific fact. And a paper from this week added yet another example:
In mammals, hearing is dependent on three canonical processing stages: (i) an eardrum collecting sound, (ii) a middle ear impedance converter, and (iii) a cochlear frequency analyzer. Here, we show that some insects, such as rainforest katydids, possess equivalent biophysical mechanisms for auditory processing. Although katydid ears are among the smallest in all organisms, these ears perform the crucial stage of air-to-liquid impedance conversion and signal amplification, with the use of a distinct tympanal lever system. Further along the chain of hearing, spectral sound analysis is achieved through dispersive wave propagation across a fluid substrate, as in the mammalian cochlea. Thus, two phylogenetically remote organisms, katydids and mammals, have evolved a series of convergent solutions to common biophysical problems, despite their reliance on very different morphological substrates.
It is another curious example of biological convergence, so rather than attempt to deny the undeniable, evolutionists now claim it as another confirmation of evolution.
Astonishingly evolutionist Ronald Hoy claims that this new finding provides “evidence for convergent evolution.” That would be quite a discovery. How, according to Hoy, do the amazing similarities in mammal and katydid hearing make for evidence that they are products of so-called convergent evolution?
It makes for a startling headline and once again gives journalists license to proclaim another confirmation of evolution. But down in the details, Hoy’s “evidence” is nothing more than circular reasoning. In a classic example of evolutionary blowback, Hoy reasons that (i) mammals and katydids evolved, (ii) their hearing designs are remarkably similar, so (iii) therefore it is proof of convergent evolution.
Or simply put, evolution is true, so therefore evolution is true.
This is a confirmation not of convergent evolution but of how evolution has corrupted scientific thinking. Fallacious reasoning such as this is, unfortunately, is the rule rather than the exception.
Religion drives science and it matters.
