Much like the finch's speciation on the Galapagos Islands, the common raver is also speciating through a process deemed by scientists as "Chemical Selection."

Similar to Natural Selection, Chemical Selection is the result of constantly exposing the brain to certain psychotropic 'designer' drugs such as Ecstasy, MDMA and Ketamine.

Although Chemical Selection occurs much faster than other evolutionary adaptations, it can be compared to the evolution of pesticide resistance in insect populations; The insects with a chromosome containing the gene conferring resistance to insecticide effectively survives the pesticide spray, in the context of man-made chemicals causing an evolutionary reaction.

Many of the speciating traits are smaller brains, short attention spans, as well as loss of saliva, bladder and smile control.
