The approach identified the proteins that best represent ancestral forms (Hox7 and Antp) and the proteins that represent new, derived versions (or were lost in an ancestor and are now missing in numerous species).
A aproximación identifica as proteínas que mellor representan a forma ancestral (Hox7 e Antp) e as proteínas que representan versións derivadas novas (ou que se perderon nun antepasado e agora están ausentes en numerosas especies).
