For many years, wall lizards have existed in three distinct color forms, each adapting to their environment in unique ways. However, recent observations indicate a significant shift in this balance.
The green variant, known as 'Hulk' lizards, has emerged as the dominant type, leading to a decline in the populations of the yellow and orange morphs.
This change raises important questions about the long-term impacts on biodiversity and the evolutionary history of these lizards, as millions of years of evolution may be at risk.
