COMPARE THE RECONSTRUCTION STANDARD

One method. Different evidence.

HOLISTIC RECONSTRUCTION · CLAIM-LEVEL EVIDENCE

How did
Neanderthals
actually live?

A first-stage Neanderthal prototype linking claims, sources, reconstruction choices and the pages that present them. Each layer distinguishes what was observed, what was inferred, what was reconstructed and what remains unknown.

Probable reconstruction · moderate confidence

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.

Evidence in context.

Explore six parts of life. Photographs and illustrations show context; the linked research supports the claims.

Flaked stone and toolmaking context. AI-generated contextual illustration, not a specimen photograph or proof of a species-specific activity.

Technology

Direct evidence · high confidence

Stone tools, hafted systems, fire, hide working and adhesives are directly represented. Organic tools are undercounted because preservation is uneven.

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

Food

Direct evidence · high confidence

Diet varied by ecology. Animal foods, cooked plants, fungi, seeds, legumes and shellfish are documented unevenly by site.

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

Cave archaeology and shared places. AI-generated contextual illustration, not a specimen photograph or proof of a species-specific activity.

Community

Strong inference · high confidence

Genomes reveal biological relatives in one cave context, but cannot supply names, roles or a universal kinship system.

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

Construction

Direct evidence · high confidence

Bruniquel proves organized construction deep inside a cave. Its practical, social or ritual purpose remains unknown.

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

Worked eagle talons and a phalanx from Krapina, with specimen markings and arrows. — Specimen photograph. Worked talons from Krapina; their original arrangement and meaning remain inferred. This is not a surviving assembled necklace. Whole image resized; no content crop.

Adornment

Probable reconstruction · moderate confidence

Modified eagle talons support display or symbolic use in some contexts; exact meanings are unrecoverable.

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

Comparative study of fragmentary remains. AI-generated contextual illustration, not a specimen photograph or proof of a species-specific activity.

Clothing

Strong inference · moderate confidence

Cold exposure and hide working support protective clothing. Cut, closures and social meaning remain reconstructed.

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

ChronologyNeanderthals 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.
