                 We measured the average difference between mothers and
                 their children, the number of species, and the degree
                 of adaptation in evolving populations of endogenously
                 diversifying digital organisms using the Pushpop
                 system. The data show that the number of species in
                 adaptive populations is higher than in non-adaptive
                 populations, while the variance in the differences
                 between mothers and their children is less for adaptive
                 populations than for non-adaptive populations. In other
                 words, in adaptive populations the species were more
                 numerous and the diversification processes were more
