The importance of understanding function and evolution

Ocklenburg et al. (2020, Laterality 2020: Entering the next decade. Laterality) provided field of laterality research with a stimulating perspective for coming decade, based on current state art in both animal and human research. Although this is paper takes many different approaches into account, we emphasize that eco-evolutionary approach needs more attention. This concerns question why organisms are lateralized first place, other words, how does lateralization enhance Darwinian fitness individual. We argue can be distinguished along four dimensions, each them requires ultimate explanations. Studying these functional evolutionary explanations development ecologically relevant tests, adapted to species at hand. It also experimental manipulation laterality, testing effect (semi)-natural conditions parameters. Tools such urgently require better understanding developmental plasticity lateralization, extending evo-devo eco-evo-devo. warn against seeing minority distribution direction or strength as being pathology minorities biology often explained adaptations by natural frequency dependent selection.
