Compound adhesives were made in southern Africa at least 70,000 years ago, where they were used to attach similarly shaped stone segments to hafts. Mental rotation, a capacity implying advanced working‐memory capacity, was required to place the segments in various positions to create novel weapons and tools. The compound glues used to fix the segments to shafts are made from disparate ingredients, using an irreversible process. The steps required for compound‐adhesive manufacture demonstrate…

Cognitive complexity is defined here as the capacity for abstract thought, analogical reasoning, cognitive fluidity, innovative thought, complex goal-directed actions, flexibility in problem-solving,

Thinking a bow-and-arrow set : cognitive implications of Middle Stone Age bow and stone-tipped arrow technology

It is shown that, when isolated, neither the production of a simple bow, nor that of a stone-tipped arrow, can be reasonably interpreted to indicate tool behaviour that is cognitively more complex than the composite artefacts produced by Neanderthals or archaic modern Homo.

90,000 year-old specialised bone technology in the Aterian Middle Stone Age of North Africa

A bone artefact from Aterian Middle Stone Age (MSA) deposits in Dar es-Soltan 1 cave on the Atlantic coast of Morocco comes from a layer that can be securely dated to ~90 ka and is significantly different from any other African MSA bone technology.

Ochre use at Sibudu Cave and its link to complex cognition in the Middle Stone Age

Ochre pieces were used experimentally for a variety of grinding, scoring and rubbing activities to record and compare the use-wear markings that each activity creates on the ochre piece. Ochre that

Encounter hunting, especially of big game, is an activity firmly associated with people who lived in the Middle Stone Age. Most hunting is assumed to have taken place in groups, using spears of

Osseous Projectile Weaponry from Early to Late Middle Stone Age Africa

Discussion about early projectile technology typically includes criteria used to distinguish artefacts used as hafted points from those employed for other purposes, associated faunal and lithic

Use-Wear Analysis Brings “Vanished Technologies” to Light

I review five “vanished technologies” from southern Africa that have been brought to light through use-wear studies of bone tools. Most of the examples discussed here represent the first recognition

Implications for complex cognition from the hafting of tools with compound adhesives in the Middle Stone Age, South Africa

Compound adhesives made from red ochre mixed with plant gum were used in the Middle Stone Age of South Africa and this ability suggests overlap between the cognitive abilities of modern people and people in the MSA.

Working‐Memory Capacity and the Evolution of Modern Cognitive Potential

Tool use is the main database to track down behavioral developments in the archaeological record and thus human evolution. Working‐memory capacity and modern cognitive potential, however, are no

Investigating the potential mixing of Middle and Later Stone Age deposits at the two sites and the possible creation of misleading assemblages concludes that Lupemban tools lack the standardization of the Howiesons Poort backed pieces, but form part of a regionally distinctive and diverse assemblage of heavy and light duty tools.

“Working‐memory capacity” is viewed as an emergent property of interactions between specialist subsystems with no homunculus‐like executive and increased mental capability is dually based on the development of more abstract representations and on the observation that the more subsystems there are, the more the mind can do at one and the same time.
