Lineage is a tricky topic because of math. Your ancestors grow in number exponentially with generation: 2 parents, 4 grandparents, 8 great grandparents, 16 great great grandparents, etc.

Taking this back 30 generations would mean 1 billion anscestors. But that’s far more than the number of humans back then.

Your lineage has consanguinity as a mathematical fact. That means we are all more related than we realize. Thus if you look hard enough, you’ll find the best and the worst of humanity in essentially every lineage. Rapists and rape survivors. Murderers and missionaries. Liberators and tyrants.

The squares with what we know about the heart of mankind: “ no line between good and evil runs through the heart of every man.” (Aleksandr Solzhenitsyn)
