Planar Preservationist and Evolved Summoned Monster

[Cleru]

Do Preservationist Alchemist with Planar Preservationist feat quality for "ability to cast summon monster I" part of Evolved Summoned Monster?

What about Ring of Summoning Affinity?

This is really boil down to whether Alchemist are "casting" or not right?

Unclear. Since the Alchemy ability (of which extracts are one part) is supernatural instead of spell-like, the FAQ on spell-like abilities counting as specific spell prerequisites (dimension door for Dimensional Dervish was the example used) doesn't necessarily count.

Personally, with the FAQ on spell-like abilities and the precedent that a preservationist can take Augment Summoning, I don't see where it would be unbalanced or against RAI. Allowing Moonlight Summons, Skeleton Summoner, Starlight Summons, Sunlight Summons, and the rings of natural attunement/summoning affinity for a preservationist adds some interesting options (especially if taking another archetype, as well).
