Final answer:
Most organisms evolve through a process called punctuated equilibrium, which involves long periods of stasis followed by bursts of rapid change. Additionally, gradualism is also a factor in the evolution process.
Step-by-step explanation:
Most organisms evolve through a process called punctuated equilibrium. This model suggests that there are long periods of little change (stasis) followed by bursts of rapid change. During these bursts of change, new species may be formed due to environmental factors such as climate change. However, it is important to note that gradualism, where small changes accumulate over time, is also a factor in the evolution process. Therefore, both punctuated equilibrium and gradualism result in the divergence of species.
