Fig. 1: Implications of long-term stable individual variation in lithic technological behaviour.
From: Reliable long-term individual variation in wild chimpanzee technological efficiency
The schematic illustrates the implications of long-term individual differences in stone tool use on four major domains (orange): the potential presence of social learning strategies, the generation of behavioural innovations, the interpretation of the archaeological record, and the presence of variation in daily energy budgets and expenditure. In turn these have four broader evolutionary implications (green): transmission via social learning, cultural evolution, technological evolution, and life history strategies and evolutionary fitness. Arrows indicate the relationships between the major domains and the broader evolutionary implications.
