Galaxy of Choices
Source Galactic Ancestries pg. 4
The galaxy known as Desna's Path is home to countless unique and diverse species. Whether they are native to the Pact Worlds, refugees from distant stars, or even visitors from other planes of existence, they've learned to coexist with one another and call this galaxy home.
A character's feature and ancestry the first is often characteristic their most used identifying when describing them. As such, each ancestry's lore is filled to the brim with ideas that inspire and help express different backstories, themes, and values. Even if you intentionally deviate from or deconstruct the ancestry's cultural norms or disguise your character to hide their ancestry, the circumstances of your character's origin and how they identify with regards to their heritage offer rich narrative opportunities to help you tell your character's unique story.
No two characters are the same, and even characters who share the same heritage might originate from different worlds, whether through abduction, migration, or convergent evolution. Humans are often the go-to example of this phenomenon, as other species often define humans by their seemingly ubiquitous presence on dozens of worlds with no known contact or shared ancestral origin. Some scholars dedicate their entire lives to trying to uncover common origins between their kinfolk on different worlds and are stunned by the genetic (and even cultural) similarities between different peoples, only to find that if there is a common link, aside from evolving on the same physical universe, it's beyond the realm of empirical investigation.
Each world is a rich tapestry of different cultures and traditions with its own histories and languages. A deity might be a core part of a pantheon on one world only to find they are completely unheard of in another's, where other gods' grand, majestic temples dominate the landscape. That said, in systems like Desna's Path, where technology, commerce, and war have created vast intersections of cultural exchange, there exist ancestral lingua francas, or common languages, that help bridge the cultural divides of shared ancestries from different planets. Thus, a vesk from Vesk-4 needn't learn a different language to communicate in Vesk with their brethren from the Pact Worlds, though they'll have ample opportunity to learn new aphorisms and colloquialisms.

Galactic Ancestries
Source Galactic Ancestries pg. 5
The ancestries presented in this book represent civilizations found all across the Starfinder setting. They might exist on countless worlds or be relegated to a single planet, such as one of the Pact World, and some of them might even have origins that trace back to other planes of existence.
One thing to keep in mind when using the ancestries presented in this book (or in other Starfinder products) is that the rules for a given ancestry can easily be used to represent a previously unencountered species. As a player, if you find an ancestry with mechanics that appeal to you but you want to approach its culture or mannerisms in a different way, then you should confer with your GM about introducing those changes into your game. Some ancestries, such as kasathas, possess mechanics highly tied to their cultural background, but these can easily be adjusted to represent different aspects of a species that uses the kasatha ancestry as a template.
Another consideration when retooling an existing ancestry in this manner is the presence of languages. If an ancestry has an existing language, such as a bantrid's Bantridi, then you should consider adjusting that language. For example, if you create a new ancestry of rolling organic balls called zamurzans that uses the bantrid ancestry in this book as a base, you should consider swapping out their language for something bespoke, like Zamurzan. Of course, it's important to review this with your GM before beginning a campaign, as a prewritten adventure won't include Zamurzan unless your GM makes appropriate alterations!

Mixed Ancestries
Source Galactic Ancestries pg. 5
A culturally diverse galaxy of biotechnology and widespread magic is rife with opportunities to play a character with more than one ancestral heritage. You can always play a character with two or more ancestries in your genealogy who still uses the rules for a single ancestry, whether or not you take the Adopted Ancestry general feat. Characters who want abilities beyond the scope of that feat might consider applying a custom mixed heritage.
Custom Mixed Heritage: You can work with your GM to create a mixed heritage for any ancestry. A custom mixed-ancestry heritage is an uncommon heritage. Choose an ancestry to tie to the heritage. You gain any of the traits of that ancestry and a new trait for your combined ancestry. You also gain low-light vision if the ancestry tied to the heritage has low-light vision or darkvision. Furthermore, this heritage lets you select ancestry feats for the chosen ancestry in addition to those from your base ancestry. You can select any options from standardized ancestry feats shared by both ancestries.
For example, a skittergoblin who selects the Ancestral Skills feat becomes trained in their choice of Goblin Lore or Skittermander Lore, plus any two of the four skills listed for the goblin and skittermander ancestries: Diplomacy, Nature, Society, or Stealth. Work with your GM if you need a custom feat to represent the combined abilities of both ancestries.

Other Ancestries

The content presented here is just the beginning of an ever-expanding suite of ancestries and heritages for your Starfinder characters. Starfinder Galaxy Guide includes six new ancestries, for example, which range from shapeshifting astrazoans to empathic dragonkin. Most Starfinder Second Edition adventures, including our Organized Play seasons, include at least one new ancestry or versatile heritage, such as corpsefolk in Guilt of the Grave World or plantlike khizars in Murder in Metal City. Some adventures include many more!
