Human beings in the past hunted and gathered for subsistence. This culture, also known as the “foraging culture” included strategies like hunting, trapping, fishing, and gathering, in order to obtain supplies. These behaviours placed demands on the body that are similar to vigorous exercises and were practiced by all humans, until 12,000 to 11,000 years ago, “when agriculture and animal domestication emerged in southwest Asia and in Mesoamerica”. Innovations such as agriculture and animal domestication introduced a solution to the foraging culture, reducing the need for hunting wildlife. However, the two inventions also created a problem: humans have become so dependent on agriculture and domesticated animals that consequently decreased our

Each group conducted a specific activity over the course of a two week period. The first group was labeled the “normal” group, where the cage that the rats were in was a plain cage with no decorations, toys, or a running wheel. The second group, the swimmers’ group, included rats that swam a little every day in a small pool. Navigating a water maze was the main task of the third group called the “learners” group. Rats in the enriched group were put in a “swank cage”, where the rats were spoiled and surrounded by toys and friends. Finally, the runners’ group ran every day on the running wheel. The end of the experiment, the runners’ group gained the most benefits from exercising, as they had an increase of 200% in the number of brain neurons created. One of the last benefits that takes place after exercising is the increase in the number of mitochondria throughout the body. Mitochondria are the “locomotives of the cell, generate power for transportation, molecule break downs, synthesis, and signalling”. In short, they produce the raw energy, ATP, required by the body to function from foods consumed. Thus, as the number of mitochondria and the energy it produces increase, the energy available for the body to utilise increases as well, allowing cells to exercise for a longer duration before
