Our core criteria follow the definition of CCE provided in Tomasello's quotation above. We suggest that the minimum requirements for a population to exhibit CCE are (i) a change in behaviour (or product of behaviour, such as an artefact), typically due to asocial learning, followed by (ii) the transfer via social learning of that novel or modified behaviour to other individuals or groups, where (iii) the learned behaviour causes an improvement in performance, which is a proxy of genetic and/or cultural fitness, with (iv) the previous three steps repeated in a manner that generates sequential improvement over time.

In contrast [to non-human species' cultural traditions], human cultures do accumulate changes over many generations, resulting in culturally transmitted behaviors that no single human individual could invent on their own.
- Boyd & Richerson give a nice explanation of CCE
