A Rational Designconcluded:
the biomechanical properties and the morphology of locust wings are functionally correlated in locusts, providing a mechanically ‘optimal’ solution with high toughness and low weight.
The research also found that distribution of the cell size across the wing followed the pattern of smaller cells tending to cluster along the wing edges where cracks might be more likely to begin. As one of the researchers concluded:
Thanks to this precise spacing of the cross veins, the cracks are always stopped before they can reach this critical length and start growing themselves. Nature has found a mechanically “optimal” solution for the locust wings, with a high toughness and a low weight.
It is another example that, as William Bialek has pointed out, biological designs are rational. That is, rather than explaining that the species are the way they are because that is the way they happened to evolve, the species have designs that can be understood according to the underlying engineering and physics principles.
And so using this rational, mathematical, approach to biology the researchers were able to do something that consistently eludes evolutionists—produce a successful prediction:
An optimal cell size of a grid-like structure such as the wing can be predicted using the “critical crack length” of the membrane, which is determined by the material’s fracture toughness and the stress applied. … An “optimal” wing cell should have a diameter of around 1132 µm. Is this the case in locust wings? Our results show that the distribution of the wing cell size in locust wings corresponds very well to this prediction, with the most common wing-cell “class” being between 1000 and 1100 µm.
These wing designs enable the desert locust to achieve tremendous feats of flying, and the designs are yet another example of evolution’s anti-realism. Biological structures certainly appear to be designed but, evolutionists insist, it is a case of false appearances. The designs are that way because that is how they happened to evolve. That, evolutionists say, is a scientific fact that we must not question.
