Which factor is typically NOT associated with evolution?

Unchanging environments typically do not drive evolution because for evolutionary processes to occur, there needs to be variable selection pressures that lead to changes in the traits of organisms over time. In stable environments where conditions remain static, species may become well-adapted to their surroundings, which can lead to a decrease in evolutionary change since there is little pressure for adaptation or diversification.

In contrast, increased competition for resources, habitat destruction, and climate change all create dynamic pressures that can lead to natural selection and ultimately evolution. These factors introduce challenges that can alter the survival and reproductive success of organisms, prompting changes in traits across generations. Thus, the presence of an unchanging environment is linked to stagnation rather than evolution, making it the correct choice in this context.
