Darwinism proved! Hawaiian crickets converge on no chirp

The killer flies have an unusual ability to pinpoint a cricket’s location using sound.
After finding its victim – a male cricket, singing to attract a mate – a pregnant fly will spray baby maggots onto the cricket’s back, which burrow in, feed, and emerge a week later leaving the husk of the hapless cricket behind.
The presence of these North American flies placed the crickets, themselves relatively recent arrivals from Australia, under pressure to adapt.
In less than 20 generations, a mutation that leaves males unable to sing spread to over 90% of the crickets on the island of Kauai. More.
Astounding proof of Darwinism if all you want is no function.
