The scientific definition of evolution refers to changes in a species or population over time.

Evolution is a long-term process. It may take millions of years and several generation for an evolution to occur. The cause of evolution can be genetic as well as environmental. The evolution is a result of mutation. Evolution generally gives rise to new species, that is different from its ancestral population.

Population is a group of similar type of organisms.  These organisms live in the same habitat, require same resources and have same kind of habits. The most essential criteria that defines a population is that the organisms of a population can mate with each other and produce offspring.

Sever21 [200]
I believe the answer for the above question is exhaustion stage.
Hans selye, described three predictable stages the body uses to respond to stressors, called general adaptation syndrome (GAS). The first stage is alarm stage, which provides burst energy, then the resistance stage where the body attempts to resist or adapt to the stressor, and finally the exhaustion stage. During the resistance stage, the body uses its resources of flight off the stressor. It is not until the next stage, exhaustion, that bodily resources are so depleted that stress-related diseases can develop.
