Chirality is a fundamental trait of living organisms, encompassing the homochirality of
biological molecules and the left–right (LR) asymmetry of visceral organs and the brain. The …

Left-Right (LR) asymmetry of the nervous system is widespread across animals and is
thought to be important for cognition and behaviour. But in contrast to visceral organ …

Lateral preference in behaviors has been widely documented in many vertebrates and
invertebrates. Such preferences are strange, puzzling, and on the surface, not adaptive …

The left and right distribution of a set of twenty‐six genes in the zebrafish pallium was
examined by RT‐qPCR experiments. The analysis comprised four general pallial markers …

Natural selection can cause similar phenotypic evolution in phylogenetically independent
lineages inhabiting similar environments. Compared to morphological, behavioral, and …

Different evolutionary interests between males and females can lead to the evolution of
sexual dimorphism. However, intersex genetic correlations due to the shared genome can …

Behavioral laterality—typically represented by human handedness—is widely observed
among animals. However, how laterality is acquired during development remains largely …

Several vertebrates, including fish, exhibit behavioural laterality and associated
morphological asymmetry. Laterality may increase individual fitness as well as foraging …
