Teachers do not copy the works of others without acknowledging their work in a proper manner. Inherent to the scientific method are the principles of classification. To have a functioning classification system, a name refers to but one object. A name referring to two items creates havoc. It did not do a native tribe any good to say the enemy were coming on horseback at a trot when they were coming at a gallop.
Trackers first observe tracks and trails as naturalists and classify what they see.
From their observations, trackers formulate hypotheses and, as scientists, test their hypotheses. Trackers, as practitioners, use their skills and knowledge in the field for their enjoyment and often to fill their stomachs. As teachers, trackers honestly pass on their knowledge to others.
