Or most people can't trace their lineage all the way back to 1809 and some ancestors just spawn into existence (or descend parthenogenetically from a single parent) at a later date.
Maybe those missing ancestors could be imputed by sampling a random other individual with known parents born in the same year.
- dhosek 3y agoI think that’s likely it. One should instead build the tree backwards starting with the most recent members of the database and then find their earliest known ancestors. These can then be assigned the magic trait based on the likelihood of it being present based on their birth year cohort (or more reasonably birth decade or some other larger bucket).
