It’s fairly troublesome to know what was on the menu for Neanderthals, significantly since smaller gadgets like birds don’t often go away many archaeological traces behind. Whereas we all know that some cooked crab and different seafood and that they hunted for bigger recreation, understanding extra about their diets is important to understanding how these extremely adaptive hominins thrived in very totally different environments. To do that, a group of scientists tried cooking trendy birds utilizing the strategies and instruments that will have been out there to Neanderthals. The method is detailed in a small study published July 24 in the journal Frontiers in Environmental Archaeology.

“Utilizing a flint flake for butchering required vital precision and energy, which we had not totally valued earlier than this experiment,” Mariana Nabais, a examine co-author and archaeologist at Institut Català de Paleoecologia Humana i Evolució Social in Spain, said in a statement. “The flakes had been sharper than we initially thought, requiring cautious dealing with to make exact cuts with out injuring our personal fingers. These hands-on experiments emphasised the sensible challenges concerned in Neanderthal meals processing and cooking, offering a tangible connection to their day by day life and survival methods.”
Neanderthal butchers
Neanderthals hunted massive animals–together with cave lions–however scientists know much less concerning the smaller avian species that some Neanderthals ate. To be taught extra, the group examined the meals preparation strategies that they could have used on varied wild birds. They had been hoping to see what software traces are left behind on animal bones and the way these traces examine to the harm attributable to extra pure causes of loss of life.
The group created an experimental database that may be in contrast with the findings from actual archaeological websites. To construct it, the group collected 5 wild birds that had died of pure causes from the Wildlife Ecology, Rehabilitation and Surveillance Centre in Gouveia, Portugal. The group chosen two carrion crows, two collared doves, and a wooden pigeon–comparable species to what Neanderthals might need eaten. To pick the cooking strategies, they referred again to proof discovered within the archeological report and ethnographic information.
Every chook was defeathered by hand. One collared dove and one carrion crow had been butchered uncooked utilizing a flint flake. The remaining three had been roasted over scorching coals till cooked, then butchered. The group discovered that this second technique was simpler than butchering the uncooked birds.
“Roasting the birds over the coals required sustaining a constant temperature and punctiliously monitoring the cooking period to keep away from overcooking the meat,” stated Nabais. “Possibly as a result of we defeathered the birds earlier than cooking, the roasting course of was a lot faster than we anticipated. In reality, we spent extra time making ready the coals than on the precise cooking, which took lower than ten minutes.”
Bones that aren’t constructed to final
The group then cleaned and dried the bones and examined them underneath a microscope for reduce marks, breaks, and burns. Additionally they seemed on the flint flake they’d used for proof of wear and tear and tear throughout butchering.
Whereas they’d used their fingers for many of the butchery, the uncooked birds wanted the flint flake. This left small half-moon formed scars on the sting. The cuts used to take away the meat from the uncooked birds didn’t go away any taxes on the bones, however the cuts geared toward tendons left marks much like ones on chook stays discovered at archaeological websites.
The roasted birds had bones that had been far more brittle. Some had fully shattered and couldn’t be recovered. Practically all of them had black or brown burns in line with managed publicity to warmth. The black stains advised that the contents of the inside cavity had additionally burned. This proof sheds signifies components of how Neanderthal meals preparation might have labored, but in addition sheds gentle on how seen that preparation could also be within the archaeological report. Whereas roasting makes it simpler to entry the animal’s meat, the elevated fragility of the bones implies that the stays won’t be discovered by archaeologists.

To realize a greater understanding of Neanderthal diets, future research might embody extra species of prey and likewise processing birds for non-food merchandise, like feathers or talons.
“The pattern dimension is comparatively small, consisting of solely 5 chook specimens, which can not totally signify the range of chook species that Neanderthals might need used,” famous Nabais. “Secondly, the experimental situations, though rigorously managed, can not fully replicate the precise environmental and cultural contexts of Neanderthal life. Additional analysis with bigger samples, assorted species, and extra various experimental situations is critical to increase upon these outcomes.”
