There's a bit of a chicken-and-egg question here: Do spotted hyenas have a more complex butter microbiome because they're a more gregarious subspecies, or were they able to become a more gregarious subspecies because they have a more complex butter biome?


To learn about hyenas, please Google "Glickman, Berkeley". You'll find the largest hyena study project ever done. If you're a true animal lover, consider donating to this project, which has shrunk somewhat over the last ten years. They've done magnificent work.

Call it 'human butter' or the universal joke.
Humans like farts..
