Climate change is accelerating the evolution of species as global warming intensifies and natural environments undergo significant alterations. This study addresses the urgent need to understand how these environmental changes impact avian populations, specifically focusing on the physiological adaptation of finch beaks on the Galápagos Islands. By employing multiple models-logistic regression, XGBOOST, and Random Forest Classifier-using the most recent data, the study investigates how changes in climate conditions correlate with variations in beak dimensions. The analysis reveals significant relationships between temperature, precipitation, and finch beak characteristics, indicating that climatic factors have a notable impact on beak morphology. The study aims to clarify the evolutionary dynamics at play and to predict future adaptations based on projected climate scenarios. The results highlight the robust correlation between climatic variables and finch physiology, providing deeper insights into the complex interplay between climate change and evolutionary biology. These findings are crucial for developing targeted conservation and adaptation strategies, helping to safeguard biodiversity in the face of ongoing climate shifts. The insights gained from this study are essential for guiding policymakers and stakeholders in implementing effective measures to mitigate the impacts of climate change on ecosystems and species survival.
