These manipulations may be carried out under managed situations in laboratory or herbal settings or arise from accidental herbal experiments. Domestication is a particularly interesting example as it usually combines edition to captive situations and selective breeding for certain traits . The evaluation between domesticated and wild type strains was key to Darwin’s theory of natural preference and since then it has enriched our understanding of the normal mechanisms of behaviour and its evolutionary principles . Studying organisms that experience been under strong synthetic choice for certain behavioural traits may facilitate the identity of genetic and physiological mechanisms underlying the expression of that behaviour e. g. and, as a result of option for one certain behaviour customarily co selects for other traits, either behavioural or morphological, uncover gene epistatic and pleiotropic effects .
