Genealogy can reveal "pedigree collapse," where one discovers ancestors are related, leading to fewer unique forebears than expected in the family tree. This often occurs in isolated communities and historical times when populations were smaller. It's a reminder that humans are more interconnected than we might think, emphasizing the shared history in our DNA.
