Introduction to Neanderthals
Understanding Neanderthal development and cognition reveals how their brains evolved, learned, and adapted, shedding light on the depth of their intelligence. By studying their brain growth, energy demands, care for the sick, and working memory, we can gain insight into their cognitive abilities.
Brain Development and Cognition
Neanderthals had different brain growth trajectories compared to modern humans. Fossil reconstructions of Neanderthal children show that their brains grew at different rates and followed distinct developmental paths, which may have influenced how neural circuits were organized and when cognitive skills matured. Additionally, their larger eyes and powerful musculature required significant brain resources for processing visual input and controlling movement, meaning a greater proportion of their cognitive budget was dedicated to sensory and motor functions. Evidence of care for the sick and elderly, such as skeletons of Neanderthals with severe injuries who lived long after those injuries, shows that groups looked after vulnerable members, indicating empathy, planning, and social cohesion. Experiments with tar production and toolmaking suggest Neanderthals could plan multi-step processes and adjust their actions on the fly, pointing to strong working memory and problem-solving skills.
Behavior and Culture
Neanderthal behavior and culture reveal a species capable of creativity, cooperation, and adaptation, traits that challenge long-held assumptions about their intelligence. They developed sophisticated stone and bone tools, such as the Mousterian industry, which were diverse and carefully made, with prepared cores and controlled flaking techniques that required planning and dexterity. They also demonstrated mastery of fire, cooking, and the use of adhesives like birch tar, with evidence from hearths and residues showing that they controlled fire for warmth and cooking, and produced tar to haft stone tools onto wooden handles. Organized hunting of large animals and evidence of cooperative care, such as cut marks on large animal bones and the survival of injured individuals, point to coordinated hunting strategies and social support within groups. Possible symbolic activities, including pigments, ornaments, and cave structures, suggest they engaged in some form of symbolic or decorative expression. The construction of stalagmite rings deep in caves indicates planning and cooperation, with the ring structures at Bruniquel Cave implying advanced spatial planning, group coordination, and perhaps ritualistic behavior in the dark. Finally, their use of natural shelters and seasonal movement shows that Neanderthals selected caves and open-air sites and moved seasonally, reflecting environmental awareness and resource management.
Conclusion
Taken together, these biological and cultural indicators show that Neanderthals were intelligent, adaptable hominins capable of planning, cooperation, empathy, and perhaps symbolic thought. Their different brain organization may have influenced the balance of their cognitive skills, but there is no evidence that they were dramatically less capable than early modern humans.
