Body and face

Fossils constrain robust proportions and craniofacial anatomy; skin, hair, scars and individual appearance remain interpretive.

What is known: Robust skeleton, characteristic cranial anatomy and substantial regional and individual variation.
What is inferred: Soft-tissue depth and musculature can be reconstructed within ranges.
What remains unknown: A specific individual's pigmentation, hairstyle, expression and surface details.

ChronologyThey were not a brief Ice Age population; they persisted across major climatic shifts and vanished near 40,000 years ago.Direct evidence · high

The beginning of the lineage depends on which fossils are classified as Neanderthal or ancestral Neanderthal.

RelationshipsSome Neanderthals and early members of our species had children together; parts of that ancestry survive today.Direct evidence · high

Ancestry percentages vary among individuals and populations; a single global percentage is misleading.

Social lifeAt one cave, researchers identified relatives living within the same community-scale context.Strong inference · high

One regional community cannot define Neanderthal social organization across their full range and history.

DietThere was no single Neanderthal menu. Diet changed with place, climate and available resources.Direct evidence · high

Dental calculus samples are few and do not measure everything eaten or the proportion of each food.

ConstructionThey organized material and maintained activity far beyond daylight inside a cave.Direct evidence · high

The structures' specific purpose is unknown; ritual, shelter and other functions cannot be distinguished securely.

Symbolic behaviorThe talons were selected and worked; interpreting the exact object remains a reconstruction.Probable reconstruction · moderate

No cord or complete assembled object survives, so the final arrangement and meaning are inferred.

ClothingThey almost certainly protected their bodies with worked hides in cold regions; the outfits shown in art are interpretations.Strong inference · moderate

Clothing need, hide processing and preserved garments are different evidence categories; regional variation was likely.

TechnologyThe adhesive is real; sweeping claims about what it proves about intelligence are not.Direct evidence · high

Production methods differed and some may be simpler than earlier experimental reconstructions assumed.
