The study of innovation in non‐human animals (henceforth: animals) has recently gained
momentum across fields including primatology, animal behaviour and cultural evolution …

Despite major advances in the study of animal tool behaviour, researchers continue to
debate how exactly certain behaviours are acquired. While specific mechanisms, such as …

The zone of latent solutions (ZLS) hypothesis provides an alternative approach to explaining
cultural patterns in primates and many other animals. According to the ZLS hypothesis, non …

Humans are distinctive in their dependence upon products of culture for survival, products
that have evolved cumulatively over generations such that many cannot now be created by a …

The environment has an important effect on the gut microbiota—an essential part of the
host's health—and is strongly influenced by the dietary pattern of the host as these together …

Extant primates, especially chimpanzees, are often used as models for pre-modern hominin
(henceforth: hominin) behaviour, anatomy and cognition. In particular, as hominin behaviour …

The notion that tool-use is unique to humans has long been refuted by the growing number
of observations of animals using tools across various contexts. Yet, the mechanisms behind …

Humans possess a perhaps unique type of culture among primates called cumulative
culture. In this type of culture, behavioural forms cumulate changes over time, which …

The emergence of flexible tool use is rare in the animal kingdom and thought to be largely
constrained by either cognitive ability or ecological factors. That mostly birds with a high …

In a recent paper in Nature Human Behaviour, Koops et al.(2022) argued that unlike most
other chimpanzee “know-how”, nut-cracking falls outside the zone of latent solutions (ZLS) …
