Squirrel evolves into flying squirrel. This is intuitive. This is logical progression and pokémon-style logic at its finest. Like a piranha evolving into a shark, a pony evolving into a unicorn, or duck evolving into a swan.
Literally squirrel -> flying squirrel is the first thing I would EVER think of for a pokémon, other than tadpole -> froglet -> frog.
