Parasites can act as powerful agents of natural selection, culling weak individuals and thereby strengthening the genetic pool of the host species. These life cycles are a key characteristic of parasitism, allowing them to exploit different environments and resources.

Economic and Medical Significance The study of parasitism is not just an academic exercise; it has profound economic and medical implications. The defining characteristic is the dependency of the parasite; it requires the host to complete its life cycle, whether for nutrition, reproduction, or a specific developmental stage.
This can range from the dramatic, like the parasitic hairworm driving crickets to water to drown, to the subtle, such as a gut parasite altering the host’s appetite or immune response. Exploitation and Nutritional Dependence A fundamental characteristic of parasitism is the exploitative nature of the relationship.
