Development of increasingly complex stone tools (Stout 2011) correlates with larger brain capacity and language development. Even with language, knowledge is limited by what can be learned, remembered, and passed on by single individuals. By < 500 kya, pace of change in the capacity to deal with multiple complexities is too fast for genetic adaptation < 50 kya increasing rate of change suggests major innovation to support accumulation of much larger volumes of knowledge.

The common distribution of language proxies across human and neanderthals in genomic, paleoanthropological, and paleoarcheological contexts show that human, Denisovan and Neanderthal common ancestor had a capacity for modern language, speech and culture (Dediu & Levinson 2013, etc.) Schöningen & Bilzingsleben Modified from Krubitzer & Stolzenberg (2014) Two extraordinary snapshots imply that linguistic capabilities already existed 400 kya in LCA Neanderthal / H. sapiens Schöningen II (single-use hunting camp 380 kya – Thieme 2005) – – – – Bilzingsleben (base camp 370 kya - Mania & Mainia 2005) – – – – – Captured, butchered and processed at least 20 horses Tools made elsewhere include 9 wood lances left (ritually?) with herd remains 4 hearths, associated tools & evidence for spit-roasting, smoking and drying Earliest evidence for compound tools 3 x 3-4 m dia. huts with hearths all oriented against wind Prey included fish, amphibians, reptiles, birds, elephants, rhinoceros, horses, bison, deer, pigs, lions, bears, wolves, hyenas, foxes, badgers, and martens Spit roasting & smoking for preservation Evidence for making & use of wide variety of stone and bone tools Paved area with artifacts suggestive of ritual activities.

Use of fire in making fine blades and points, or use of ochre and beads may have been developed & lost several times before being fixed in culture Even where ideas can be expressed in words, an individual’s ability to remember detail is limited.

In larger populations subgroups can maintain specialized knowledge Becoming settled – surmounting the knowledge capacity of nomadic life in the post-glacial era Nomads limited to technology they can carry or fabricate on demand Accumulating technological knowledge enables more effective use of smaller geographic areas – larger populations accumulate more knowledge Becomes practical to establish core living areas with permanent goods & structures (e.g., specialized tools, houses, and structures for cultural activities and processing and storage of food and other property) Reduced contact with
