Scientists left 14 lizards on 7 islands, and evolution took 7 different paths
- Scientists placed one male and one female brown anole on each of seven Bahamas islands in 2005 to study evolution.
- The islands had similar conditions, but the lizards began with different traits because of the pairs chosen by chance.
- Over four years, natural selection favoured shorter hindlimbs suited to the islands’ narrow branches and scrubby vegetation.
- Yet the original differences remained, showing how chance and natural selection can shape evolution at the same time.
