Scientists discover wild gorillas sing while they eat – and the tunes might reveal more about human evolution than we ever imagined.
The Day Scientists Heard Gorillas Humming
Deep in the rainforests of the Congo, researchers once assumed gorilla mealtimes were silent affairs – just the crunch of leaves and occasional grunts. Then, in 2016, primatologist Eva Luef noticed something extraordinary: the gorillas were singing.
Not just random noises, but deliberate, rhythmic vocalizations:
- Low, rumbling hums synchronized with chewing
- Distinct “food calls” for favorite snacks (like sweet bamboo shoots)
- Individual “signature songs” – each gorilla had a unique style
“It wasn’t just functional communication,” Luef told New Scientist. “This was something joyful. They were basically saying ‘Mmm, this slaps’ with their mouths full.”
Decoding the Gorilla Gourmet Playlist
A PLOS ONE study analyzed over 1,000 hours of gorilla meals, revealing surprising musical complexity:
The Breakfast Choir Phenomenon:
- Pitch patterns matched chewing tempo (faster chewing = higher notes)
- Duets occurred when two gorillas shared food
- Infants tried to mimic adults, like toddlers singing along to the radio
Favorite “Singing Foods”:
- Bamboo (the gorilla equivalent of pizza)
- Wild celery (their “comfort food”)
- Figs (cue the gorilla equivalent of “Oh my god, you HAVE to try this”)
Why This Isn’t Just Cute – It’s Revolutionary
These food songs challenge three big assumptions about animal behavior:
- “Music is uniquely human”: Nope. Gorillas structure sounds rhythmically without training.
- “Animals only vocalize for survival”: These hums served no obvious purpose beyond enjoyment.
- “Language evolved just for warnings”: The songs suggest communication began around shared positive experiences like family dinners.
“Imagine proto-humans singing about mammoth steaks around a fire,” says Harvard primatologist Richard Wrangham. “This could be the origin of both music and mealtime gossip.”
The Elvis Presley of Gorillas
Meet Itebero, a silverback from Rwanda who became famous in research circles:
- His “fig jam” was 20% longer than other gorillas’ songs
- Females often joined in, creating call-and-response harmonies
- When he died, his group was unusually quiet for weeks
“We can’t prove they were mourning,” says Luef. “But the silence felt… intentional.”
How to Listen to Gorilla Jazz (Without Getting Trampled)
Want to hear it yourself? The rules of gorilla concert etiquette:
- Stay downwind (they hate perfume)
- No eye contact (it’s like yelling “PLAY FREEBIRD!”)
- Morning shows only (post-lunch naps are sacred)
Pro tip: This BBC clip captures rare duets – listen for the basso profundo “crunch hums.”
The Bigger Picture: Music as Evolutionary Glue
The study’s wildest implication? Music may have evolved to bond groups during vulnerable moments – like when our ancestors gathered to eat.
Supporting evidence:
- Chimpanzees drum on tree roots during meals
- Bonobos “peep” rhythmically while foraging
- Human cultures worldwide link food and music (see: dinner parties, harvest festivals)
“Shared meals and shared sounds create trust,” says Wrangham. “Gorillas show us the recipe for society might literally be ‘food + tunes’.”
Unanswered Mysteries (That’ll Haunt Your Next BBQ)
- Do gorillas have “guilty pleasure” songs? (Evidence suggests yes when eating fermented fruits.)
- Could we teach them instruments? (Researchers are debating ethically questionable xylophone experiments.)
- Do they judge bad singers? “Oh absolutely,” laughs Luef. “One juvenile got nipped for being off-key.”
