The Pok√©mon Go craze is still going strong, as players scamper about the great outdoors trying desperately to catch ‚Äėem all. And amid all the accompanying media frenzy, there‚Äôs one burning question on everyone‚Äôs mind: where‚Äôs the science?

Yes, there is a science of Pok√©mon‚ÄĒspecifically, a 2012 satirical study that appeared in the humorous journal, Annals of Improbable Research entitled, ‚ÄúA Phylogeny and Evolutionary History of the Pok√©mon.‚ÄĚ The authors‚ÄĒthen a group of budding young entomologists at the University of Caifornia Davis‚ÄĒtraced the evolutionary history of the 646 fictional species of ‚Äúpocket monsters,‚ÄĚ even creating an impressive 16-generation phylogenetic or evolutionary tree.


Why do this at all? Well, the paper itself cites the need to document all the species because they are ‚Äúthreatened by the Pok√©mon fighting rings that are growing rapidly in popularity, particularly among urban youth.‚ÄĚ But really, it was just a fun side project.

‚ÄúI had a lull in my dissertation research and decided to spend the weekends and downtime making this phylogeny,‚ÄĚ lead author Matan Shelomi said at the time. ‚ÄúIt took at least a month to actually collect all the data, which I did manually by scrolling through Pok√©mon websites.‚ÄĚ

Considering the creatures are entirely made up, the tree turned out surprisingly well, although a fierce debate over possible errors raged on Reddit when the tree was first published. It was also a fitting tribute to Pokémon’s creator: Japanese video game developer Satoshi Tajiri, who collected insects in his childhood and once considered becoming an entomologist.
