Evolved structures

Evolved structures refer to physical features or systems that develop over time through the process of evolution, driven by natural selection and adaptation. These structures are the result of incremental changes that improve survival or reproductive success in specific environments. For example, the wings of birds evolved from earlier limb structures to enable flight, while the human eye improved to enhance vision. Evolved structures are often specialized for their functions, reflecting a lineage’s history and environmental pressures, and they exemplify how organisms gradually adapt to their surroundings through generations.
