A mere few decades ago, culture was thought a unique human attribute. Evidence to the
contrary accumulated through the latter part of the twentieth century and has exploded in the …

Cumulative technological culture (CTC) refers to the increase in the efficiency and
complexity of tools and techniques in human populations over generations. A fascinating …

Despite its theoretical importance, the process of stone tool-making skill acquisition remains

The dominant view of cumulative technological culture suggests that high-fidelity
transmission rests upon a high-fidelity copying ability, which allows individuals to reproduce …

The extent to which larger populations enhance cumulative cultural evolution (CCE) is
contentious. We report a large-scale experiment (n= 543) that investigates the CCE of …

Large-scale social networks are thought to contribute to polarization by amplifying people's
biases. However, the complexity of these technologies makes it difficult to identify the …

Although the theoretical foundations of the modern field of cultural evolution have been in
place for over 50 y, laboratory experiments specifically designed to test cultural evolutionary …
