This paper advances an hypothesis that the primary adaptive driver of seasonal migration is
maintenance of site fidelity to familiar breeding locations. We argue that seasonal migration …

Explaining how animals respond to an increasingly urbanised world is a major challenge for
evolutionary biologists. Urban environments often present animals with novel problems that …

Behavioural plasticity is believed to reduce species vulnerability to extinction, yet global
evidence supporting this hypothesis is lacking. We address this gap by quantifying the …

The social intelligence hypothesis states that the demands of social life drive cognitive
evolution,,. This idea receives support from comparative studies that link variation in group …

Evidence is growing that human modification of landscapes has dramatically altered
evolutionary processes. In urban population genetic studies, urbanization is typically …

Reconstructing the evolution of brain information-processing capacity is paramount for
understanding the rise of complex cognition. Comparative studies of brain evolution typically …

Relative brain sizes in birds can rival those of primates, but large-scale patterns and drivers
of avian brain evolution remain elusive. Here, we explore the evolution of the fundamental …

Recent work in animal cognition has focused on how animals respond to new or changing
environments. Although many species are currently in decline, other species are thriving in …

Large brains and behavioural innovation are positively correlated, species-specific traits,
associated with the behavioural flexibility animals need for adapting to seasonal and …

Urbanization is a major driver of local biodiversity losses, but the traits that determine
whether species are able to tolerate urban environments remain poorly understood. Theory …
