The lack of natural predators or agents of disease in the new environment allows invasive species to outcompete the natives, leading to their takeover of the community. While some invasive species may be more aggressive, have higher reproductive potential, or come from geographically isolated regions, these factors alone cannot explain the success of invasive species in all situations. The role of humans in selecting invasive species may also play a part, but it is not the most widely accepted hypothesis.
