Cornelius Hunter, a software engineer / biologist with a Ph.D in bioinformatics from UIUC explains the latest discovery of biological convergence on his blog. (H/T Tweet from J. Warner Wallace)
The theory of evolution states that the species arose spontaneously, one from another via a pattern of common descent. This means the species should form an evolutionary tree, where species that share a recent common ancestor, such as two frog species, are highly similar, and species that share a distant common ancestor, such as humans and squids, are very different. But the species do not form such an evolutionary tree pattern. In fact this expectation has been violated so many times it is difficult to keep track. These violations are not rare or occasional anomalies, they are the rule. Entire volumes have been written on them. Many examples are the repeated designs found in what, according to evolution, must be very distant species. Such evolutionary convergence is biology’s version of lightning striking twice. To explain this evolutionists must say that random mutations just happened to hit upon the same detailed, intricate design at different times, in different parts of the world, in different ecological niches, and so forth. The idea that the most complex designs we know of would spontaneously arise by themselves is, itself, not scientifically motivated and a real stretch of the imagination. But for the same intricate designs to arise independently by chance is even more of a stretch. That is why evolutionist’s claim this week that they have found evidence for convergent evolution was so intriguing.
[…]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.
I’m a software engineer, and we re-use components all the time for different programs that have no “common ancestor”. E.g. – I can develop my String function library and use it in my web application and my Eclipse IDE plug-in, and those two Java programs have no common ancestry, but they do have a common designer. So you find the same bits in two different programs because I am the developer of both programs.
Previously, I blogged about another example of convergence reported by Science Daily. One of the predictions of intelligent design theory is that examples of convergence, which is really just re-use of common code by the designer, will be everywhere in nature. And that predictions just keeps getting confirmed as science marches forward, and the primitive religion of naturalism retreats.
