Not moved around, they were designed in the order they were implemented and then removed if they weren't going to be used and left gaps in the code for MissingNo. to exist. If you know a little bit about programming this is easier to do than actually swapping the code, but also leaves a lot of vacant data that adds to file size despite being unused garbage data. The reason for this is because when you're programming you need to have all data refer to a specific slot, it's not as easy as just programming something and then dumping it in a separate slot. That's why it took until RS to organize the Index by National Dex order, back in GS instead of making new slots they filled old, empty slots

Look at their JP names anon, nobody gives a fuck about localization fanfiction when discussing the relevancy of the design process
>Caterpie/Trancel/Butterfree
>Konpan/Morphon
"Venonat" was designed first, then Venomoth, then the entire Caterpie line in order next to each other. There weren't many lines in RG that are as clean cut as Caterpie. My personal pet theory is instead of Venonat intending to evolve into Butterfree, Caterpie/Metapod were designed to evolve into Venomonth but someone inserted a new butterfly evolution and that stuck while later in development they decided to combine Venonat/Moth to consolidate the dex and played up the mystery in the dex entries (like the JP only book)
Alternatively people are seeing shit that was never there like the Ilima/Mina type specialist swap (the characters that were swapped were Molayne and Dexio)
