The All Common Ancestors Generation

This project is a simulation of how many people can stem from the same ancestor, something Simon has learned from James Grime’s “Every Baby is a Royal Baby” video on Numberphile. In this simplified version, there’re only 6 people per generation. Simon was throwing two dice to determine who the two parents were for every person (in the case when both dice came out to be the same number, this was considered “virgin birth” or simply that the father had come from outside the limited sample Simon was working with).

the present generation

Some parents don’t have the digits corresponding to their children written next to them, but letters N and E: N means that that person from the parent generation had no children and is therefore related to no one from the future generations; E on the conrrary, means that that person “has been busy” and is related to everyone in the next generation!
