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 reliable.
