There are some beautiful examples around immune systems!! Especially plants have benefited from 'domesticating' transposons to shuffle their disease resistance genes around for increased diversity -> increased chance of defense. https://genomebiology.biomedcentral.com/articles/10.1186/s13059-017-1341-9 https://genomebiology.biomedcentral.com/articles/10.1186/s13... There are some wonderful specific examples where a plant 'stole' one specific TE and uses it to generate diversity on the fly!
