As a result, one can conclude that the species now living on different islands had descended from different ancestors. Some species, however, are similar because they were living under similar ecological conditions and thus exposed to similar pressures of natural selection. - Different animals ended up evolving certain striking features in common. Look at mammals, reptiles, and birds; each of those creatures has backbones.
