The brain is a trait of central importance for organismal performance and fitness. To date,
evolutionary studies of brain size variation have mainly utilized comparative methods …

Heterogeneous genomic divergence between populations may reflect selection, but should
also be seen in conjunction with gene flow and drift, particularly population bottlenecks …

Many fish populations have experienced declines in recent decades due to anthropogenic
disturbances, such as overfishing and habitat exploitation. Despite management actions …

Parallel evolution and the extent to which it involves gene reuse have attracted much
interest. Whereas it has theoretically been predicted under which circumstances gene reuse …

Phenotypic plasticity can influence evolutionary change in a lineage, ranging from
facilitation of population persistence in a novel environment to directing the patterns of …

Antipredator defensive traits are thought to trade‐off evolutionarily with traits that facilitate
predator avoidance. However, complexity and scale have precluded tests of this prediction …

Animal body armour is often considered an adaptation that protects prey against predatory
attacks, yet comparative studies that link the diversification of these allegedly protective …

The evidence for adaptive phenotypic differentiation in mobile marine species remains
scarce, partly due to the difficulty of obtaining quantitative genetic data to demonstrate the …

Adaptation to novel environments can be based either on standing genetic variation or
variation attributable to new mutations. When standing genetic variation for a functional …
