The complexity of nervous systems alters the evolvability of behaviour. Complex nervous
systems are phylogenetically constrained; nevertheless particular species-specific …

The pattern of individual variation in brain component structure in pigs, minks and laboratory
mice is very similar to variation across species in the same components, at a reduced scale …

The evolution of neural circuitry differs from that of other structures in a significant respect.
Natural selection cannot physically eliminate most neuronal pathways for obsolete functions …

Recent physiological studies of neural circuits have shown that single circuits can produce
more than one behavior, and that different circuits can combine to produce a single, new …

We propose that insights from the field of evolutionary developmental biology (or 'evo-devo')
provide a framework for an integrated understanding of the origins of behavioural diversity …

We suggest that variation in mammalian behavioural flexibility not accounted for by current
socioecological models may be explained in part by developmental constraints. From our …

The nervous system is evolutionarily conservative compared to the peripheral appendages
that it controls. However, species-specific behaviors may have arisen from very small …

Most studies of behaviour examine traits whose proximate causes include sensory input and
neural decision‐making, but conflict and collaboration in biological systems began long …

The behaviour of animals is the result of adaptations and constraints. To what extent a
particular behaviour pattern can be attributed to the relative strengths of these two forces is …
