Convergent refers to the process where different ideas, technologies, or entities come together to form a unified whole. This concept is often seen in various fields, such as science, technology, and business, where diverse approaches or innovations merge to create new solutions or products. In biology, convergent evolution describes how unrelated species develop similar traits or adaptations due to facing similar environmental challenges. For example, the wings of birds and bats evolved independently, yet both serve the same function of flight, illustrating how different paths can lead to similar outcomes.
