The reason why it was important that the experimental islands lack lizards based on the Dr. Losos experiment because it is one way of having the study to be made easier as the ectomorph has become isolated because they are lacking lizards on the island.
It was necessary in Dr. Losos experiment that the experimental islands lacked lizards because the isolation of each ecomorph was vital to make it easier to observe and study. The lack of the lizards allowed for an unhindered observation. The experimental islands were later introduced with the lizards, This experimentation helped in studying the process of adaptation and natural selection.
Hence, the answer is 'it was important that the islands lacked lizards so that the ecomorphs could be easily studied'.
