There didn’t seem to be anywhere online that showed this information in a convenient table, so here’s the vanilla version (i.e. not Unchained) of the Summoner class’ Eidolon evolutions. All data is from the D20pfsrd site.

Eidolon Evolutions by Level Requirement:
1-Point evolutions (not shown in table): You can choose any 1-point evolutions regardless of level. However, some can be taken again (stacked) at higher levels. These are shown below in the appropriate level section.
Legend:
(#) – indicates that the evolution costs that number of evolution points.
(+#) – indicates that at this level, if you already have the evolution, you can spend additional points to improve it.
(#+#) – first number indicates original cost of the level 1 evolution, but you can now spend # more points to improve it to the next level.
(++) indicates that if you have the Evolution, it levels up at this point automatically (for free).
