The three-spined stickleback (Gasterosteus aculeatus) is a small teleost fish that is ubiquitous across the Northern Hemisphere. Among the behaviours that have been characterised in this species is ritualized courtship, aggressiveness and parental behaviour.

The threespine stickleback Gasterosteus aculeatus species complex is an important natural model for speciation research because it includes several replicated sets of coexisting, divergent forms that are also experimentally tractable. Recent research

The central assumption of evolutionary theory is that natural selection drives the adaptation of populations to local environmental conditions, resulting in the evolution of adaptive phenotypes. The three-spined stickleback (Gasterosteus aculeatus)

Our understanding of the molecular basis of evolution is being revolutionized by increasing access to an ever-expanding number of genomic tools and resources (84,100, 162). Vast strides are being made in addressing some of the most fundamental and long-standing
