Episode Transcription

CODY: Hi! You’re about to get smarter in just a few minutes with Curiosity Daily from curiosity-dot-com. I’m Cody Gough.

ASHLEY: And I’m Ashley Hamer. Today, you’ll learn why monkeys imitate other species’ accents. Then, you’ll learn about a new way to think about how humans use information, with author Caleb Scharf.

CODY: Let’s satisfy some curiosity.

Monkeys change their "accent" to get along with other species (Ashley)

When you move somewhere new, you might find yourself adopting the local accent and using local idioms. That makes sense: matching other people’s style of speaking can cut down on miscommunication and conflict. It turns out that monkeys think so, too. Scientists have discovered that certain primates adopt their neighbors’ “accent” to keep the peace in the jungle.

 

This research focused on two types of squirrel-sized monkeys living in the Amazon rainforest. One species, called the pied tamarin, is critically endangered and keeps to a very specific region of the rainforest. The other species, the red-handed tamarin, is hardier and spread across the Amazon — and that means it sometimes encroaches on the pied tamarins’ turf. The two species compete for the same resources, so things can get ugly when their paths cross.

 

But sometimes a stern warning can prevent physical violence. Each species has a set of calls for different purposes, like wooing a potential mate or warning a rival they’re too close for comfort. They’re sort of like words or phrases that make up a larger monkey language. The two tamarins have a similar set of calls, but they use slightly different accents. It’s like American English versus British English: They’re the same language, but Americans say “toe-may-toe” and Brits say “toe-mah-toe.”

 

When similar species take up the same territory, the groups can sometimes change things up to cut down on competition. Often, that change is done to differentiate themselves: they might evolve different wing markings or mating rituals to ensure nobody gets confused. But the opposite can also happen: birds and frogs are known to match their calls to other nearby species to make communication easier. Researchers from Anglia Ruskin University wondered if the same might be true of these overlapping tamarins. After all, the easier it is for someone to understand your warning call, the easier it is for them to obey it.

To find out, they compared recordings of 15 tamarin troops’ calls from three different spots throughout the rainforest: One where they knew the different species lived together and two where they didn't. Sure enough, in the shared region, the red-handed tamarins’ calls sounded a lot more like their neighbors’. The technical term for adopting another species’ accent is “asymmetric call convergence,” and this was the first time scientists found primates doing it!

 

This is an important step in our understanding of how species interact when they share territory. When animals want to keep the peace, many set themselves apart. But tamarins take a different tack: when you can’t beat ‘em, join ‘em.

Information is kind of like an animal. It evolves, it mutates, and the better it is at surviving, the further it spreads. In a way, information is alive. And today's guest says that's not just a metaphor: humans and information have evolved together in a symbiotic relationship kind of like the bacteria in our guts. One of us couldn't survive without the other. Caleb Scharf is the director of the Columbia Astrobiology Center and the author of the new book, "THE ASCENT OF INFORMATION: Books, Bits, Genes, Machines, and Life's Unending Algorithm." He told us how this idea occurred to him.

Information definitely has a dark side. Again, that was Caleb Scharf, the director of the Columbia Astrobiology Center and the author of the new book, "The Ascent of Information: Books, Bits, Genes, Machines, and Life's Unending Algorithm." Caleb will be back tomorrow to explain how the dataome might affect extraterrestrial civilizations.

RECAP

Let’s recap the main things we learned today

  1. CODY: Primates actually change their accents to keep the peace with other species. When a red-handed tamarin crosses paths with a pied tamarin, it’ll alter its warning call to adopt the other species’ way of speaking in order to cut down on miscommunication — and avoid a fight. This is the first time we’ve seen this in primates, and it’s an important step in our understanding of how species interact. 
  2. ASHLEY: Humans create and retain and pass along information in a way that no other species seems to do. And Caleb Scharf calls that externalized information the “data-ome.” It’s like a microbiome or a genome. And just like the stuff we find in other -omes, information can be useful or useless — or, good or bad. That’s important to keep in mind as we share information, because it takes energy and resources to actually store it. And we don’t want resources like environmental costs to outweigh the benefits we reap from the information we have.

ASHLEY: The writer for today’s first story was Steffie Drucker.

CODY: Our managing editor is Ashley Hamer, who was also an audio editor on today’s episode.

ASHLEY: Our producer and lead audio editor is Cody Gough.

CODY: We’re gonna store some pretty useful information in a new podcast episode for ya, so join us again tomorrow to learn something new in just a few minutes. It’s a responsible use of the data-ome, after all.

ASHLEY: And until then, stay curious!
