Food quality-driven variation in the link between innovation and survival in semi-natural populations of wild mice

Abstract Innovation underpins adaptation to environmental challenges, yet its link to fitness remains unclear. This may reflect context-dependent effects, with fitness benefits emerging primarily under poor environmental conditions or among individuals in poorer condition. Howeve...

Social cues on stone tools outweigh raw material properties in wild primates

1. Abstract The ability to select appropriate tool material enabled early hominins access to new resources and environments. The underlying mechanisms driving tool selection effectively remain unknown. Observations of extant primates have demonstrated strong selectivity for speci...
