Which classification method involves categorizing organisms based on easily identifiable traits?

The classification method that involves categorizing organisms based on easily identifiable traits is artificial classification. This system relies on external characteristics, such as size, color, or shape, rather than genetic relationships or evolutionary history. For example, one might classify animals with similar features together, like grouping all birds in one category due to their feathers and beaks, even if they are from very different evolutionary lineages.

This approach is straightforward and can be useful for quickly identifying and grouping organisms in a practical or observational context. However, it does not always reflect the true evolutionary relationships among organisms since it focuses primarily on superficial traits. This method is particularly useful in fields like botany or zoology when identifying and cataloging species based on their observable characteristics.
