B) Given that there is no hereditary passing down of beak depth the beak depth in the population would clearly vary, but as the generations went on beak depth would continue to trend towards the evolutionary depth that this new plot of offspring is. i) Among adults before a drought beak depth would be not very deep ii) Given that they are the same adults as before the drought their beaks are
