Neanderthal Homo sapiens neanderthalensis
Neander Valley, Germany 1856
Age: 40-50,000Significance: First human
fossil acknowledged as such, and first specimen of Neanderthal. Most dismissed it as a freak, but Doctor J. C. Fuhlrottspeculated that it was an ancient human.
Questions about NeanderthalsHow were they distinct from us?Where did they come from?How human were they?Why were they different?Where did they go?
Neanderthal Cranial MorphologyMidface prognathismAlveolar-zygomatic ridgeLarge nasal openingLarge anterior teethRetromolar gapDouble brow ridgesLow foreheadTeardrop-shaped craniumOccipital bunNo chinLong, semiflexed basicraniumLarge cranial capacity
“Old Man” of La ChapelleH. sapiens neanderthalensisor H. neanderthalensis
La ChapelleAux-Saints,
FranceAge: 50,000 yearsCranial Capacity: 1625 cc
Early studies of this elderly male mistook symptoms of advanced age for signs of brutishness
Kebara Cave, IsraelLynne Shepartz, 1983Age: 60,000 years
Neanderthal skeleton, lacking cranium and legs. Includes a modern-looking hyoid (throat) bone and distinctly broad, flat fingertip bones.
Kebara 2: “Moshe” Homo sapiens neanderthalensisor Homo neanderthalensis

Modern
Neaderthal SkeletonLarge, wide rib cageLong clavicleWide scapula with more muscle
attachments along rear edgeLarge shoulder jointLarge elbow jointBowed, short forearmWide hipsLarge hip joint, rotated outwardsHand with strong grip and wide
fingertipsLong, thin superior pubic ramusRounded, curved and thick-walled
femur shaftLarge, thick patellaShort, flattened and thick-walled
tibiaLarge ankle jointWide, strong toe bones
Cold Adaptation?Body proportions– Broadened hips and
shoulders– Shortened lower arms and
legs
Large nasal and sinus passages

WHY?War?Funerary ritual?Prey?Peaks, then fades
Unsolved Mysteriesabout the appearance of modern people:
�1. Where did they come from?2. Why did they coexist, then suddenly replace others?
3. Why the radical change in culture at 40k, long AFTER first appearance of sapiens?
