Scientists are blaming an unsuspecting creature for disturbing a 75,000-year-old Neanderthal burial: burrowing bees. These bugs could have hidden pollen beneath a Neanderthal’s stays, tricking researchers into considering the Neanderthal had been buried on prime of a mattress of flowers, a brand new research finds.
The flower burial interpretation blossomed over half a century in the past, when researchers discovered the positioning of Shanidar, a rocky cave within the Zagros Mountains of Iraqi Kurdistan that held a number of Neanderthal burials. Considered one of these, which scientists known as Shanidar 4, grew to become often called the “flower burial” when researchers found clumps of pollen from flowering vegetation within the soil beneath an grownup male Neanderthal.
The burials at Shanidar, initially excavated within the Fifties and Nineteen Sixties, had been the primary proof that Neanderthals, cousins on our evolutionary tree, engaged in ritual depositing of lifeless our bodies.
Though proof of Neanderthal burial is not controversial within the discipline of archaeology, the interpretation of pollen as proof of a flower-adorned burial ritual remains to be debated.
Within the new research, printed Aug. 28 within the Journal of Archaeological Science, a group of researchers led by Chris Hunt, a paleoecologist at Liverpool John Moores College within the U.Okay., reexamined the pollen proof from Shanidar 4 and located that burrowing bees had been a greater rationalization for the pollen than a Neanderthal funeral ritual.

Soil samples from on prime of and beneath the burial had been initially studied in 1975 by two palynologists — pollen specialists — who decided they got here from 5 identified and two unidentified taxa, or organic teams. They prompt that every one of those vegetation had been obtainable to be picked on the identical time, possible between late Might and early June.
Whereas Hunt and his group largely agree with the sooner identification of the plant species, they found that the vegetation truly develop at barely completely different instances of the 12 months, calling into query the earlier interpretation that Neanderthals gathered flowers to bestow on the lifeless.
Throughout excavations by Hunt and his group in 2016, they seen a possible various rationalization for the pollen: historic mud-lined bee burrows near Shanidar 4. These ground-nesting bees might have drilled into the dust and deposited collected pollen as they moved by way of the burrows.
The combined clumps of pollen aren’t indicative of complete flowers being laid down, the researchers wrote of their article. As a substitute, they recommend that it’s way more possible that “pollen was collected and deposited in clumps by bees.”
Hunt and his group suppose the pollen is probably going historic, even perhaps intently contemporaneous with the Neanderthal burial. However neither the pollen nor the bees could be immediately dated.
“There have been profitable experiments immediately relationship pollen grains,” Hunt informed Reside Science in an e mail. However bee exoskeletons will not be straightforward to radiocarbon-date, and “the extent of Shanidar 4 is older than radiocarbon will prolong, at about 75,000 years.” (Radiocarbon relationship can reliably date natural gadgets as much as 50,000 years outdated.)
Angie Perrotti, a palynologist who runs the Palynology and Environmental Archaeology Analysis Lab (PEARL) who was not concerned within the research, informed Reside Science in an e mail that Hunt and colleagues made a “compelling argument” for pollen introduction by way of burrowing bees. “This case underscores the essential function of exact sampling and systematic archiving of sediment and pollen samples to permit for the reproducibility of prior analysis,” she stated.
Whereas Hunt and colleagues’ work has not substantiated the flower a part of the “flower burial,” they affirm that the tight cluster of burials at Shanidar stays extremely vital to our understanding of Neanderthals and famous that “woody tissue” samples collected from the positioning could maintain the important thing to studying extra about their burial rituals.
“I favour the concept the Neanderthals put branches and different vegetation over the our bodies,” Hunt stated. Putting the spiky species Centaurea solstitialis (yellow star-thistle) on prime of, somewhat than beneath, the deceased Neanderthals might have defended the our bodies from scavengers. “However the proof is fairly equivocal, and I am nonetheless engaged on the contexts,” Hunt stated. “So watch this area…”
