What to know about Europe's aversion to eating insects may have deep ecological and evolutionary roots

The article discusses a study by the Institute of Evolutionary Biology regarding the history of insect consumption (entomophagy) in humans. It details genomic and dental analysis suggesting that while Neanderthals and tropical populations consumed insects more frequently, northern Eurasians developed a reduced capacity to digest chitin over time.

What happened

Europe's aversion to eating insects may have deep ecological and evolutionary roots Sadie Harley Scientific Editor Robert Egan Associate Editor In recent years, human population growth, coupled with the climate crisis, environmental pressures, and current…

Why it matters

With 1,611 insect species listed as edible, organizations such as the Food and Agriculture Organization of the United Nations (FAO) have proposed insects as a sustainable food source.

Common ground

However, despite the fact that hundreds of millions of people already consume them, Western societies continue to show aversion to entomophagy.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.

Claim 1: “a study by the Institute of Evolutionary Biology (IBE), a joint center of the Spanish National Research Council (CSIC) and Pompeu Fabra University (UPF), has used genomic analyses to reconstruct insect consumption over the past thousands of years.”
CORROBORATED
The claim is confirmed by multiple web search results and Wikipedia. Wikipedia verifies the IBE is a joint center of UPF and CSIC, and web results confirm they conducted the genomic analysis on insect consumption.

Claim 4: “The study also revealed that Neanderthal chitinase genes facilitate better digestion of insects, as also observed in the only Denisovan specimen analyzed.”
INSUFFICIENT EVIDENCE
No evidence was provided in the search results that specifically mentions the Denisovan specimen or the specific function of Neanderthal chitinase genes facilitating better digestion.

Although the 'Evidence for claim 8' section was empty, the evidence provided for claim 6 explicitly mentions: 'The most abundant DNA remains in Neanderthal dental calculus correspond to dipterans, the group of insects that includes flies and mosquitoes'.
