Two New Thoughts

Persistance Hunting

Persistence hunting is a type of hunting where the predator uses a combination of running and tracking to pursue the prey to exhaustion. Nowadays it is very rare among humans hunting animals, but it is seen in a few Kalahari bushmen and the Tarahumara or Raramuri people of Northern Mexico. It has been thought to be one of the earliest forms of human hunting.
Persistence hunting requires endurance running - running many miles for extended periods of time. Among primates endurance running is only seen in humans and is thought to have evolved 2 million years ago.

Systems Thinking

Systems thinking is a unique approach to problem solving in that it views certain "problems" as parts of an overall system, rather than focusing on individual outcomes and contributing to further development of the undesired element or problem. ^[1] Systems thinking is a framework that is based on the belief that the component parts of a system can best be understood in the context of relationships with each other and with other systems, rather than in isolation. The only way to fully understand why a problem or element occurs and persists is to understand the part in relation to the whole.^[2] Standing in contrast to Descartes's scientific reductionism and philosophical analysis, it proposes to view systems in a holistic manner. Consistent with systems philosophy, systems thinking concerns an understanding of a system by examining the linkages and interactions between the elements that compose the entirety of the system.
Systems thinking attempts to illustrate that events are separated by distance and time and that small catalytic events can cause large changes in complex systems. Acknowledging that an improvement in one area of a system can adversely affect another area of the system, it promotes organizational communication at all levels in order to avoid the silo effect. Systems thinking techniques may be used to study any kind of system — natural, scientific, engineered, human, or conceptual.
