Listen to me children, “Insects evolved before bats. ”
“How do we know that? Ha ha, this is just common sense, really.
“When a bat flies in the night it makes sounds that are of a frequency that our human ears cannot hear. We did not evolve ears to hear these calls because bats are not our predators. But for insects, bats are a big danger, and so insects evolved special ears to hear these bat calls.
“Before bats came on the scene, moths and other nocturnal insects owned the night sky, flitting about unmolested by predators.
“When bats made their appearance, the insects had to evolve a novel anti-bat strategy.
“Children, what do you think they evolved? Yes, they evolved special ears so that they could hear the echolocating calls of hunting bats. Look, it says so in Mr. Wade’s book, The Science Times Book of Mammals, Lyons Press 1999, p. 20.”
Unknown to our poor teacher, Dr. Plotnick and Dr. Smith found that the tympanal ears, which they researched in crickets and katydids belonging to fossils dated to be much older than the first bats, were exactly as they are in today’s crickets and katydids.
The way they modified the earlier theory to suit their findings was very unimaginative, to put it mildly. All they had to say was that the insects evolved in preparation for bats before the bats evolved.
