Description: Can you pick out the mossy leaf-tailed gecko lying against the tree trunk in this photo? How is the appearance of the gecko a benefit in terms of survival? Given what you learned about evolution, natural selection, and genetic information in this chapter, describe how the gecko's coloration might have evolved.

Key Concepts

Evolution

Evolution is the process by which species change over time as a result of changes in their genetic makeup. These changes occur through mechanisms such as mutation, genetic drift, and natural selection, leading to diversity among organisms and the development of traits that enhance survival in specific environments.

Natural Selection

Natural selection is the process by which individuals with traits that are better suited to their environment are more likely to survive and reproduce. This mechanism increases the frequency of beneficial traits in a population over successive generations, driving the process of adaptation.

Adaptation

Adaptation refers to traits that have evolved via natural selection to improve an organism's ability to survive and reproduce in its environment. In the context of camouflage, an adaptation might involve coloration or patterns that help an organism blend in with its surroundings, making it less visible to predators.

Genetic Variation

Genetic variation is the diversity of alleles and traits within a population. It provides the raw material upon which natural selection acts, allowing beneficial adaptations, such as camouflage, to arise and be passed on to future generations.
