In 2014, scientists placed 100 wall lizards on five empty Greek islets; three years later, the island descendants were larger, bit harder, and showed bigger differences between males and females

In 2014, Aegean wall lizards were introduced to five Greek islands, leading to significant growth in size and strength. This introduction also resulted in marked sexual dimorphism, with notable variations in growth rates between males and females. Similarly, a preceding study on Italian wall lizards highlighted rapid adaptations over decades, showcasing how island ecosystems play a crucial role in shaping evolutionary paths through changes in bite force and head morphology.
