=Gradual evolution, also known as “phyletic change,” is the evolution of species involving an entire population rather than a branching event, as in Cladogenesis.(Wikipedia)

e.g. Biston betularia (peppered moth): replacement of White moths by Black forms in Britain after industrial revolution (since this change occured within the species, this is anagenesis)

Compare with Cladogenesis
