In the last decade, cultural transmission experiments (transmission chains, replacement, closed groups and seeded groups) have become important experimental tools in investigating cultural evolution. However, these methods face important challenges, especially regarding the operationalization of theoretical claims. In this review, we focus on the study of cumulative cultural evolution, the process by which traditions are gradually modified and, for technological traditions in particular, improved upon over time. We identify several mismatches between theoretical definitions of cumulative culture and their implementation in cultural transmission experiments. We argue that observed performance increase can be the result of participants learning faster in a group context rather than effectively leading to a cumulative effect. We also show that in laboratory experiments, participants are asked to complete quite simple tasks, which can undermine the evidential value of the diagnostic criterion traditionally used for cumulative culture (i.e. that cumulative culture is a process that produces solutions that no single individual could have invented on their own). We show that the use of unidimensional metrics of cumulativeness drastically curtails the variation that may be observed, which raises specific issues in the interpretation of the experimental evidence. We suggest several solutions to these mismatches (learning times, task complexity and variation) and develop the use of design spaces in experimentally investigating old and new questions about cumulative culture.

What does Evo-devo offer for a better understanding of cultural evolution? Cultural evolutionists with a biological bend typically focus on the relation between genetic evolution and cultural change, a research program referred to as gene-culture coevolution. Development of the human organism is usually left unattended by cultural evolutionists, and so are the processes involved in the production of cultural phenotypes. Moreover, Evo-devo research has yet to have any marked impact on the social sciences. Examining how Evo-devo can contribute to the study of cultural evolution means understanding how cultural evolution and development shape one another. However, it is necessary to first clarify just what sorts of developmental processes we are interested in. There are two albeit not mutually exclusive candidate answers to this question. First, we can be interested in the interactions between cultural evolution and biological development – how does the development of human individuals and the cultural evolutionary process shape one another? Alternatively, we can be interested in the interactions between cultural evolution and the generative mechanisms involved in the production of cultural phenotypes. The objective of the present discussion is to address both understandings of the relations between Evo-devo and cultural evolution.
