Over-engineered bugs a puzzle for evolution

Over-engineering in nature is a problem for evolution. There are numerous examples already known of this—creatures which have been 'over-equipped' for environments they have never faced or which don't exist naturally anywhere on Earth.

For example, tardigrades1 can survive being subjected to extreme laboratory treatments (radiation, cold temperature, hydrostatic pressure) far more severe than any Earth environment. As an evolutionist observed, "With such an arsenal of adaptations for survival, tardigrades appear to be over-engineered."2

Similarly, the bacterium Deinococcus radiodurans can survive 12 million rads of gamma radiation, whereas natural radiation on Earth is nowhere more than a small fraction of that. "It is certainly a mystery how this trait has developed and why it persists," said one evolutionary biologist, dismissing desperate suggestions from fellow evolutionists that it arose elsewhere in the solar system.3

The problem for defenders of evolution, according to their own theory, is that an organism will possess only the attributes it needs to survive. That's all that natural selection can select for! So when organisms are discovered to have supra-optimal design, it bewilders evolutionists.

The latest example is the fruit fly, Drosophila melanogaster—specifically, the ability of its odour receptors to detect unfamiliar chemicals in drugs and explosives "that they have not evolved to process."4
