Cultural Adaptability

I had a question I was hoping someone would be able to answer. If I'm a Human and I take Adopted Ancestry, can I later on grab Cultural Adaptability and grab say Natural Ambition in order to gain a first level class feat?

Um, why would you go through your adopted ancestry if you're human to start with? Humans can take Natural Ambition in any ancestry feat slot.

So let's say you're an elf instead. You can take the general feat Adopted Ancestry: Human and then get Natural Ambition in any remaining ancestry feat slot.

Or you could take Adopted Ancestry: Halfing, then because of that you can take Cultural Adaptability: Human in any 5+ ancestry slot. That gets you a free 1st-level human feat, so you could take Natural Ambition there. And since you are now elf, halfling, and human as far as your ancestry feats are concerned, you can also take Natural Ambition in any remaining ancestry slots.

Hope something in there answers your question.

EDIT: Not actually positive the last (elf-halfing-human) example works. Can Cultural Adaptability give you Adopted Ancestry if you already have Adopted Ancestry from a general feat? Maybe not.

I'm human for the statistical bonuses, the plan is to grab Halfling Luck at level 1, id rather have that than the Human alternative. At level 5 grab Cultural Adaptability to take Natural Ambition because I need another class feat, then later on going to acquire Guiding Luck.

So you're starting as a human with the Versatile heritage, using the general feat that gives you to take Adopted Ancestry (halfling), then using your regular 1st-level ancestry slot to take Halfling Luck. That all works fine. But at level 5 why grab Cultural Adaptability as an adoptive halfling to get Natural Ambition instead of just taking Natural Ambition directly as an actual human?

Oh I didn't know I could take human feats if I took Adopted Ancestry, I thought I had to drop all my human feats that's why I posted like I did. Interesting so you have access to both races once you take Adopted Ancestry.

Ah! Much is now clear, as they say ;-)

Yes, Adopted Ancestry adds options but takes none away. It doesn't change your traits, either---you still have the Human & Humanoid traits but not the Halfling trait.
