Description: 昆蟲的飛行可能是演化中最重要的功績之一。Michael Dickinson 談家中常見的果蠅如何用精巧地翅膀飛行。這歸功於聰明的拍打動作和有力且靈活的飛行肌肉。但這一切的祕訣是：難以置信的果蠅大腦。（攝於 TEDxCaltech）

Michael Dickinson 談果蠅如何飛行

Fruit flies accomplish astonishing feats of flight thanks to their complex yet remarkably small brains, which pack about 100,000 neurons. In the blink of a human eye, a fly can detect danger, calculate its position, and launch into the air, beating its wings 220 times per second. Instead of being simple, these brains use clever strategies to multitask and make the most of their limited hardware. The result is a creature whose behavioral range rivals much larger animals, defying assumptions about intelligence and complexity.
