>Professor Oak of the Kanto region, who studies the relationships between Pokémon and humans.
First game to feature catching Pokemon
>Professor Elm of the Johto region, who studies Pokémon breeding patterns.
Introduced breeding and baby Pokemon
>Professor Birch of the Hoenn region, who studies Pokémon habitats.
Uhhh...weather effects? I can't put this to a new gameplay mechanic.
>Professor Rowan of the Sinnoh region, who studies Pokémon evolution.
Added a bunch of new evolutions for old Pokemon and new methods of evolution
>Professor Juniper of the Unova region, who studies the origins of Pokémon.
Also can't put this to a new mechanic. Maybe its in reference to the semi reboot nature of Gen V and it only having new Pokemon?
>Professor Sycamore of the Kalos region.
Anyone know what he studies? Was it in the demo or anything?
