Final answer:
The Passenger pigeon was most likely intentionally over-hunted in order to gain control over territory, leading to its extinction. The American bison was also intentionally over-hunted for control over territory and to displace Native American tribes.
Step-by-step explanation:
The species that was most likely intentionally over-hunted in order to gain control over territory is the Passenger pigeon. The extinction of the Passenger pigeon in the early 20th century was largely due to the large-scale hunting of these birds for food and feathers. The demand for Passenger pigeons was so high that their populations rapidly declined and they eventually went extinct.
Another example of intentional over-hunting for control over territory is the American bison. In the 19th century, bison populations were decimated through hunting as a means to control and displace Native American tribes who depended on bison for their sustenance and way of life.
