Neanderthals' use of complex adhesives shows high cognitive abilities
New evidence that Neanderthals may have used complex adhesives for tools is prompting renewed debate over how their cognitive abilities compared to modern humans. Commenters weigh archaeological and genetic findings, question earlier assumptions that portrayed Neanderthals as less intelligent “brutes,” and explore whether they were a separate species, an extinct human lineage, or part of a broader, intertwined hominid family. The conversation also branches into what allowed Homo sapiens to outcompete other hominins—ranging from social complexity and trade networks to endurance and sheer ruthlessness—and what this implies for human exceptionalism.
Baseline views on Neanderthal cognition
- Some expected Neanderthals to be cognitively similar to modern humans given physical similarity and interbreeding; others say assuming equal intelligence without strong evidence is unwarranted.
- Older scientific attitudes explicitly described Neanderthals as “brute-like,” influencing public perception and textbooks that framed them as a dead-end due to inferiority.
- Several commenters note that recent popular coverage tends to sensationalize “Neanderthals were smarter than we thought” stories.
Evidence, brain size, and intelligence
- One line of argument cites lower brain-to-body ratios as evidence of slightly lower intelligence; others counter this is oversimplified and likely numerically wrong.
- Counterpoints: Neanderthals had larger brains than pre-industrial humans of similar height, but also larger eyes, implying more brain volume for visual processing rather than higher cognition.
- Overall, commenters agree intelligence level is uncertain and highly debated; many findings are weak, ambiguous, or could be attributed to early H. sapiens.
Adhesives paper and attribution skepticism
- The linked adhesive study is flagged as unable to rule out early modern humans as the makers, due to dating/context issues at the site.
- Some suspect many “advanced Neanderthal” artifacts may instead indicate earlier H. sapiens presence, or mixed occupancy, making attributions unclear.
Species, interbreeding, and genetic evidence
- Debate over whether Neanderthals should be seen as a separate species versus an “extinct race” of humans, given interbreeding and small genetic distance.
- Some emphasize robust genomic work showing distinct lineages; others highlight low overall human diversity and argue the species distinction is partly conventional.
- Discussion of Neanderthal DNA in modern humans (small percentages but implying real hybrid ancestors) and asymmetric patterns in Y-chromosome vs mitochondrial DNA, with multiple possible interpretations.
Why Sapiens survived
- Proposed factors: larger and denser populations, long-distance trade networks, better endurance hunting, and extreme competitiveness/violence.
- Some frame the outcome as ecological inevitability of overlapping niches, not moral failure; others express sorrow that multiple intelligent hominins couldn’t coexist.
Moral and philosophical reflections
- Tension between “poor Neanderthals, we were brutal” and “our survival toolkit and cultural evolution are extraordinary and costly.”
- Broader analogies drawn to human exceptionalism, racism-like thinking, and even to potential future human–AI competition over resources and niches.
