But if this marvel has you doubting the validity of that old story of random mutations, and other lucky events, creating the birds and the bees (and everything else for that matter), then think again.
The newly discovered micro fly is yet another proof of evolution for it is a vicious parasite. It lays its eggs in the heads of ants which the larvae will consume from the inside. Eventually the ant dies and its head falls off. It is indeed, as Tennyson put it, a world “red in tooth and claw.” Surely it must have evolved. As Darwin explained to a friend in 1860:
I own that I cannot see as plainly as others do, and as I should wish to do, evidence of design and beneficence on all sides of us. There seems to me too much misery in the world. I cannot persuade myself that a beneficent and omnipotent God would have designedly created the [parasitic wasp] with the express intention of their feeding within the living bodies of caterpillars, or the cat should play with mice.
This is the power of evolutionary thought. We have no idea how the world could have arisen spontaneously, but it must have.
