Leopard Gecko

# Evolutionary Timeline of the Leopard Gecko The Leopard Gecko (*Eublepharis macularius*) belongs to the Eublepharidae family, a group of eyelid-bearing geckos that diverged from other geckos due to environmental adaptations in arid regions. Their evolution reflects broader squamate (lizard) diversification, driven by climatic shifts, predation pressures, and habitat changes from forested to desert environments. Key milestones include: - **Jurassic Period ( ~180 million years ago)**: Emergence of early Gekkota (gecko infraorder) from squamate ancestors, adapting to arboreal lifestyles with adhesive toe pads. - **Cretaceous Period ( ~100 million years ago)**: Divergence of Eublepharidae from other geckos, influenced by aridification and continental drift, leading to ground-dwelling traits and functional eyelids for dust protection. - **Paleogene Period ( ~50 million years ago)**: Specialization in Asian arid habitats, with nocturnal behavior evolving to avoid diurnal predators and extreme heat. - **Neogene Period ( ~20 million years ago)**: Refinement of traits like fat storage in tails for survival in resource-scarce deserts, shaped by ongoing climate drying. - **Modern Era**: Human-influenced distribution, but core adaptations remain tied to rocky, semi-desert environments in South Asia.
