Fruit Flies Put Evolution in Reverse (AFP, Jan. 12, 2009)

Different groups of insects were starved, exposed to greater humidity and so on in various experiments, and as a result developed specific characteristics, molded by these conditions.

Henrique Teotonio and colleagues put these various populations back into the ancestral environment and let them reproduce for another 50 generations.

They then took a close look at a telltale stretch of DNA, on Chromosome 3, to see whether "reverse evolution" had taken place.

They have to just be poking fun at themselves.
