One thing leads to another

People have been practicing Martial Arts since prehistory, and through the years literally thousands of different styles or disciplines have been formed. Many of these styles were formulated based on family traditions and reenactments of animals in the wild. Whatever their base of idea we now have thousands of different styles and millions of different schools. However there is one common denominator, all these styles were used against each other, and there for helped each other evolve. The northern styles such as Wushu with their Long fist techniques were tested against southern styles like praying mantis kung fu in times of war and civil unrest. Over the years as these arts grew more acute and finite and as politics took place over war, we begin to see a boiling over effect in Martial Arts. An effervescent act of progression where arts not only begin to reflect one another, but also begin to spontaneously create entirely new disciplines of practice. Take for instance Jiu jitsu. Jiu Jitsu began in japan (believe it or not MMA Crowd) and was a very hard style the tournaments and practice often left practitioners injured. Over time a prominent Jiu Jitsu Practitioner, Jigoro Kano, eventually restructured the art in a way where people could train and compete while sustaining much less injury. And thus Judo or the "gentle way" was born, it is now practiced world wide. Just another example in Martial Arts of how one thing leads to another.
