Just being funny. I liked hearing about wholesome geese, it painted a much prettier picture than the untitled goose game. Maybe that was an incel goose.

For a serious answer I'll say with humans: yes we have both but instinct no longer applies, with us it's a choice. That's why we have a great social respect for lifetime partnerships: The choice took mental strength to uphold. It would be different if our DNA forced all of us to be monogamous...or rapists...or whatever cats are.

After hearing what assholes ducks are about mating I wonder how a cousin species can be so wholesome... Swans and penguins too, right? (That was one of reddits viral moments with the girlfriend crying tears of joy about Swan love)

Maybe they can teach that to their duck bros? Explain in quacks that this is why nobody rescues, rehabs, and reunites ducks.

To simplify: you let the AI do the brainstorming at the cellular level but you test the most successful of those predictions using traditional methods.
