The behavior of calcium abundance is examined in relation to the evolutionary stage of some Am stars in three star clusters. It appears that, the more the Am star is evolved, the less is its calcium deficiency. This observation makes it possible to suppose that Delta Delphini stars and A-F giant stars photometrically similar to classical Am stars could be descendants of the Am stars.
