Researchers role-played as Neandertals to learn how they hunted birds

Juan Negro crouched in the shadows just outdoors a cave, sporting his headlamp. For a quick instant, he wasn’t a scientist. He was a Neandertal, intent on catching evening meal. As Negro waited in the cold, darkish evening, crowlike birds named choughs entered the cave. Negro the “Neandertal” then snuck in and commenced to hunt.

He was function-participating in to analyze Neandertals’ looking techniques. Neandertals ended up an historical species carefully relevant to modern individuals. These hominids lived in Europe and Asia thousands of a long time back. Experts have observed piles of chough bones in some caves visited by Neandertals. The bones have marks remaining by historic tools and tooth. That recommended these historic tolk chowed down on the birds.

Researchers in Spain attempted to seize choughs with their bare palms in roosting web-sites this kind of as this setting up. The work was section of an experiment to see if Neandertals could have productively hunted the birds.J.M. García

Negro and his colleagues wondered: How may possibly Neandertals have caught this prey?

Those people historical hunters probably went following choughs at evening, the researchers believed. These birds are challenging to capture when they are flying in the course of the day. But at night, their actions turns them into sitting down ducks. The birds roost in teams and frequently return to the similar location — even if they’ve been hunted there in advance of.

To check this concept, Negro and his colleagues pretended to be Neandertals. The researchers armed them selves with butterfly nets and lamps. These resources were being stand-ins for the nets and fireplace that Neandertals may perhaps have made use of. In groups of two to 10, the researchers snuck into caves and other spots across Spain the place choughs roost. Then, the researchers worked to catch as lots of birds as they could.

Using flashes of gentle from flashlights to mimic fire, the “Neandertals” dazzled and baffled the choughs. The birds frequently fled into dead-conclude spots of the caves. There, they could be conveniently caught with bare fingers. Searching trips to 70 sites snared much more than 5,500 birds in all. Later on, the birds were introduced unharmed. The researchers described their exploits in the September Frontiers in Ecology and Evolution.

Negro claims this was “the most fascinating piece of research” he’s at any time done. Negro is an ornithologist, so he understands birds. He operates at Spain’s Countrywide Study Council’s Doñana Organic Station. That is in Seville.

Choughs can be caught with out fancy resources, this experiment showed. Searching them just needs teamwork and the protect of night time. Neandertals could have employed this method to capture choughs, the researchers say. But whether Neandertals essentially caught birds this way stays not known.

If this is how Neandertals hunted, these historical hominids have been cleverer than they are frequently supplied credit rating for.

Consistently catching choughs would involve various styles of smarts, claims Ruth Blasco. She’s an pro in Neandertal diet regime at the Catalan Institute of Human Paleoecology and Social Evolution. That is in Tarragona, Spain. Neandertals would have had to be capable to anticipate their foreseeable future nutritional requires. Then they’d will need to devise a hunting strategy. And that would involve a deep understanding of chough actions, Blasco says.

Purpose-playing for investigate is not as unusual as it seems, Blasco notes. It is “commonly used … to infer processes that took place in the previous.” Other researchers have pretended to be Neandertals applying replicas of wooden spears. All those experiments confirmed that Neandertals could have hurled the weapons to hunt prey at a distance.

Negro’s team utilised butterfly nets to catch birds fleeing by means of cave openings. But “the most straightforward detail was to seize the birds by hand,” Negro says.

“You have to be intelligent to seize these animals, to process them, to roast and take in them,” he notes. Earlier scientific studies have revealed that Neandertals could also have been superior at catching seafood. Most people “tend to imagine that [Neandertals] ended up brutes with no intelligence,” Negro claims. “In point,” he states, “evidence is accumulating that they had been quite near to [human].”
