So, there's a nice example from a commonly known fiction we can look to: Klingons.
At one point (I think it might have been in ST: ENT, but i might be wrong on that), Trek makes it clear that all the Klingon obsession with combat and glory is cultural. A Klingon scientist (!) notes to a Starfleet officer that there was a time, not all that long ago in Trek-terms, in which Klingons valued science and literature, and all. But, for reasons, a cult of Kahless came to cultural dominance, and, then everything went to heck in a handbasket with "warrior culture".
All that stuff where another Klingon asks Worf, "Do you feel the call of battle in your blood?" are trying to portray their culture as a bio-essentialist fact.
And that's the problem with bio-essentialism, in a nutshell.
