World is based on Predator Prey relationships where there are multiple species
The idea is that a species is identified by a genome. The genome is encoded in DNA which can be thought of as a series of ones and zeros which can be also thought of as a number.
Each species can be thought of as having attributes expressed by the genome. In identifying what is a Predator and what is Prey we will make a rule that a species can eat another if it has one less bit.
