Standardized Ancestry Feats in Your Campaign
Source Galactic Ancestries pg. 6
GMs might want to customize their campaign even further by using standardized ancestry feats for other ancestries, or by modifying the scope of the standardized ancestry feats. These are optional suggestions for how GMs might adjust their games to include standardized ancestry feats in ways beyond their intended use. Players should always consult their GMs before making changes to their character options.
Standardizing Other Ancestries
Source Galactic Ancestries pg. 6
You might want to use standardized ancestry feats for characters who select ancestries and heritages from other sources, including Pathfinder Second Edition. The easiest way to apply these feats to other sources is to examine those ancestries for similar feats and replace them with these standardized options. Comparing physiologically and thematically similar ancestries in this book to those found in other sources can also help you analyze which feats are most compatible. This is especially helpful if you use the ancestry paragon variant rule with a party that includes members of ancestries from sources that have fewer feat options than those in Galactic Ancestries.

The selection of standardized ancestry feats and their specific options represent the ancestries and cultures of the Starfinder setting. With your GM's permission, you can adjust the feats and options for other settings or situations. For example, gnomes can normally select any burrowing animal for Ancestral Pest, but a settlement of gnomes on a forested moon who magically bond with squoxes could select Ancestral Pest (squox) instead; such gnomes would be unable to select a burrowing creature like a mole for Ancestral Pest.
