Evolution of living beings has had success because of the competitive instinct. How this feature did appear?.
Searching about the (mathematical) theory of chaos I found that elements that survive in an interuaction usually make themselves more complex, Can this theory explain the development of the competitive instinct?

Flukes happen in every medium. Those that can self propogate fill the medium and spread to others.

Remember, it only has to heppen once.

Instead of chaos theory maybe game theory. Zero sum and non-zero sum games. Co-operation instead of competition.

Good read that goes into this
