Abstract

Climate change poses an urgent threat to ecosystems, species, and populations through anthropogenic environmental changes like deforestation, soil and water contamination, and rising temperatures. However, species extinction is not inevitable; adaptation through a process called evolutionary rescue can enable populations to survive. Evolutionary rescue occurs when a declining population due to environmental changes adapts and recovers, typically showing a U-shaped population growth curve. This report explores the factors influencing evolutionary rescue, such as genetic variation, environmental deterioration rate, dispersal and migration patterns, and species interactions. The study reviews theoretical frameworks and recent empirical research, highlighting examples like zebrafish and Amazonian lizard species. Findings indicate that while evolutionary rescue is possible, its success is dependent on the availability of suitable habitats and high genetic diversity. Conservation strategies must prioritize habitat preservation, genetic diversity, and proactive interventions to enhance species resilience. Understanding and facilitating evolutionary rescue is crucial for reducing the impacts of climate change on biodiversity.
