Experimental models for testing hypotheses about cumulative cultural evolution
The rapid appearance (over evolutionary time) of the cognitive skills and complex inventions of modern humans has been attributed to “cumulative cultural evolution” (henceforth CCE), the accumulation of knowledge and skills over generations. To date, researchers have only been able to speculate about the reasons for the apparent absence of this phenomenon in nonhumans, and it has not been possi...
متن کاملUnderstanding cumulative cultural evolution.
In a narrow critique of two early papers in the literature on cumulative cultural evolution, Vaesen et al. (1) misunderstand the work they criticize, mischaracterize multiple lines of research, and selectively ignore much evidence. While largely recycling prior criticisms, they provide no new models, evidence, or explanations (2). Not only do their criticisms of Henrich’s (3) and Powell et al.’...
متن کاملDivergent Cumulative Cultural Evolution
Divergent cumulative cultural evolution occurs when the cultural evolutionary trajectory diverges from the biological evolutionary trajectory. We consider the conditions under which divergent cumulative cultural evolution can occur. We hypothesize that two conditions are necessary. First that genetic and cultural information are stored separately in the agent. Second cultural information must b...
متن کاملCumulative Cultural Evolution and Demography
The idea that demographic change may spur or slow down technological change has become widely accepted among evolutionary archaeologists and anthropologists. Two models have been particularly influential in promoting this idea: a mathematical model by Joseph Henrich, developed to explain the Tasmanian loss of culture during the Holocene; and an agent-based adaptation thereof, devised by Powell ...
متن کاملTesting Hypotheses About Interaction Terms in Nonlinear Models
A recent, widely discussed contribution to econometric practice by Ai and Norton (2003) has proposed an approach to analyzing interaction effects of variables in nonlinear models. The authors focus attention on a binary choice (logit) model, though their results are easily extended to other nonlinear models. The main result of the study applies to a model that contains an interaction term, such as
