Environmental changes can also disrupt arms races. Climate change, habitat destruction, and invasive species may alter the balance of power, allowing once-subdued predators to flourish or leaving prey without time to adapt. In such cases, evolutionary adaptations may become maladaptations—once-helpful traits that are now liabilities.

Evolution is an important field of study for scientists. It covers the study of changes organisms have undergone over time in response to different factors in their environment. All organisms, including humans, evolve over time. Evolution occurs through natural selection, and is a force that has shaped every organism living today.
