Hominin Evolution in the Mid- to Late Pleistocene
• Defining Anatomically Modern Homo sapiens– Large and gracile skull– Rounded cranium– Large, pyramidal mastoid process– Smaller face– Canine fossa– Chin– Long lower limbs

Archaic Homo sapiens• European Archaic Homo sapiens
500,000 - 600,000 years ago– Boxgrove– Sierra de Atapuerca
• African Archaic Homo sapiens– 600,000 years ago– Bodo– Ndutu
• Asian Archaic Homo sapiens– 130,000-200,000 years ago– Jinniushan– Narmada

Behavior of Archaic Homo sapiens
• Stone Tools–Middle Paleolithic (Middle Stone Age)• Levallois Technique
• Biodegradable Tools– Stone-wood composite tools

Behavior of Archaic Homo sapiens (cont’d)
• Big Game Hunting– Schöningen– Boxgrove
• Fire, Campsites, and Home Sites– No proper hearths– Terra Amata

The Neandertals
• Geographic and Temporal Distribution– 27,000-150,000 years ago– Europe, Near and Middle East, Western Asia– Subspecies of Homo sapiens?
• History of Neandertal Discovery– First discovered in 1830 at Engis cave, Belgium– 1856: limestone quarry in the Neander Valley
(Neanderthal)

The Neandertals (cont’d)
• Neandertal Anatomy and DNA: Built for the Cold– Cranial• Double-arched brow ridges• No canine fossa• No chin• Long and low vault• Midfacial projection• Large juxtamastoid eminence• 1600cc cranial capacity (male) • 1300cc cranial capacity (female)

The Neandertals (cont’d)
Neandertal Anatomy and DNA: Built for the Cold (cont’d)
– Teeth• worn anterior teeth
• upper incisors have thick enamel on lingual surface
• taurodontism

The Neandertals (cont’d)
Neandertal Anatomy and DNA: Built for the Cold (cont’d)
– Postcranial• massive build• short stature• barrel chest• short limbs• heavy muscle markings on bones• gracile superior pubic ramus

The Neandertals (cont’d)
Neandertal Anatomy and DNA: Built for the Cold (cont’d)
– DNA• 1997: DNA from original Neandertal remains have been
extracted, amplified, and sequenced• Mezmaiskaya: the DNA of this subadult specimen and a
number of other individuals have been successfully analyzed• 2010: nuclear DNA was analyzed and a draft of the
Neandertal genome published

The Neandertals (cont’d)
Children may have developed
faster than human children
In general, Neandertal may
have developed at a similar
pace to modern humans
Growing Up Neandertal

The Neandertals (cont’d)
• Health and Disease– Evidence of traumatic injury: Neandertals lived
hard lives; most skeletal remains show injury–Why so many skeletal injuries?• too close to prey while hunting?• fractures may vary by geographic region according to
the ruggedness of terrain

Neandertal Behavior
• Material Culture– Anterior dentition as tool– Mousterian tradition– Association with Chatelperronian tradition– Wooden spears?
Coping with Cold– Migration– Fire– Hides– Structures

Neandertal Behavior (cont’d)
• Hunting and Subsistence– Heavy meat reliance– Kebara site
– Cannibalism• as subsistence
• Burials– Spy Cave– La Ferrassie– No grave goods
Copyright © 2013 Pearson Education, Inc. All rights reserved.
Neandertal Behavior (cont’d)
• Ritual and Symbolic Behavior– Very little in the Neandertal archaeological
record to indicate symbolic behavior–Mousterian sites: some incised bones
recovered– Pierced animal teeth may have been items of
personal adornment (Arcy-sur-Cure, France)– An incised plate of a mammoth tooth, from the
site of Tata
