Some of the investigations that scientists have carried out on the flight systems of flies and other small insects are detailed below. The conclusion emerging from this is that no haphazard, trial-and-error force or entity other than Allah can have created the complexity of even a fly.
The flight muscles of many insects such as the locust and dragonfly contract powerfully as a result of stimuli emitted by the nerves that control their every movement. In the locust, for example, signals sent by each nerve cause the flight muscles to contract. By working alternately, not against each another, two complementary groups of muscles, the so-called elevators and depressors, allow the wings to rise up and beat down. Locusts beat their wings 12 to 15 times a second, and in order to be able to fly smaller insects must beat theirs even more rapidly. Honeybees, wasps and flies beat their wings from 200 to 400 times a second, and in midges and some parasites only 1 millimeter (0.03 inch) in size, that rate rises to an astounding 1,000 times a second! Wings beating too fast for the human eye to see have been created with a special structure in order to exhibit such sustained performance.
