How do predators and prey evolve together?

In endless evolutionary arms races, predators and prey drive each other's adaptations through the process of natural selection. This coevolution drives biological innovation throughout ecosystems. Cheetahs develop speed to capture gazelles. Gazelles counter with evasive means. This creates extraordinary biological phenomena that do not exist elsewhere.

The rate of adjustment is determined by the breeding cycles. Insects change rapidly due to their short generation times. The trees change slowly, but over the course of centuries. I have chronicled the development of ultrasonic hearing in a species of moths over a period of fifty generations. This rapid change demonstrates the immediate effects of evolution. The rapid change in development in response to environmental changes states the condition of rapid evolutionary change.

These interactions produce biodiversity. Several species of prey develop special parasites against the same predator. Different hunting methods evolve in response to varying forms of prey. This "speciation effect" occurs because new ecological niches emerge, supporting more complex ecosystems. Coevolution becomes the driving force behind biological diversity.

Human activity disrupts the balance that's usually present. Pesticides decrease the density of insect prey to the extent that birds cannot adapt. If overhunted, predator populations can't recover. Climate change desynchronizes the timing of evolutionary interactions between prey and predator. Conservation involves supporting these complex interactions through sustainable practices and the establishment of habitat corridors.
