We tend to think everything has a purpose and is designed to fulfill an objective, but is this true? Some things exist simply because they contributed to their survival and reproduction, not because they fulfilled some grand design.
Teleology is the philosophical concept that proposes things have a goal towards which they strive. It posits that an inherent purpose drives objects, events, or phenomena.

For example, a simple illustration of teleology can be found in a seed growing into a tree. The seed’s purpose is to develop into a fully-grown tree. It follows a predetermined trajectory, guided by its inherent nature, to reach its intended outcome of becoming a mature plant. From this perspective, the growth and development of the seed are seen as directed towards a specific end or purpose.
In the context of evolution, it’s essential to acknowledge that teleological language, which ascribes a purpose or goal, can be misleading. While using such language as a convenient shorthand may be tempting, it should not be taken literally.
The peppered moth’s change in color exemplifies this point. The moth did not intentionally decide or purposefully change its color, and evolution did not intend to modify its appearance. There was no inherent purpose or goal behind the color change.
As the environment changed, lighter-colored moths became more vulnerable to predation, while darker-colored moths had a survival advantage due to their increased visibility. Rather than saying the moth evolved to avoid being eaten, it is more accurate to state that, as the environment changed, darker-colored moths were more likely to survive and reproduce.
Therefore, it is crucial to recognize that teleological language, when discussing evolution, is a convenient but misleading shorthand. It is a tool to aid our understanding and communication, but it should not be interpreted as implying a deliberate intention or purpose within the natural processes of evolution.
To better understand evolution, we must avoid attributing purpose or intention to natural processes. Recognizing that traits may emerge simply because they enhance survival and reproduction, not due to any inherent goal, is essential. This perspective shifts our focus from purpose to function, aligning with a more accurate understanding of evolutionary mechanisms.
