Professor Kauri's Research

Professor Kauri is the Professor that gives the player his/her starter pokémon. She is living on the starting island because of her special type of research.

Pokémon Speciation
Professor Kauri studies the way Pokémon adapt to their environment. After years and years of living in a habitat and interacting with other Pokémon, a dominant type emerges in that area. For example, after spending years on the starting island, she has found that the bug pokémon there grow to be the strongest of all the bug Pokémon found in the Absque region.

She doesn't have much evidence to support her theory though, if only she could send someone out to to collect data on all the Pokémon around the region....
