Teleology is the philosophical study of purpose or design in natural phenomena. It suggests that certain processes or entities exist for a specific end or goal, rather than merely by chance. This concept is often associated with the idea that nature has an inherent direction or purpose, influencing how we understand biological and physical systems. In the context of biology, teleology can be seen in the way organisms adapt to their environments. For example, the wings of birds are often viewed as having evolved for the purpose of flight, illustrating how features can be interpreted as serving specific functions that enhance survival and reproduction.
