How did the iguana evolve over time?

Iguanas evolved through a process of natural selection, adapting to diverse environments across their habitats in the Americas and the Caribbean. Ancestors of modern iguanas diverged from common reptiles around 200 million years ago, developing features like herbivorous diets and specialized limbs for climbing. Over time, various species emerged, each adapting to specific ecological niches, leading to variations in size, color, and behavior. This evolutionary process has resulted in the wide array of iguana species we see today.
