Eight generations back, you have 256 grandparents who never knew you'd exist.
means The line of people you descend from — your forebears collectively, and the heritage they pass down through the generations.
from From Old French ancestre, descendant of Latin antecessor, 'one who goes before' — from ante ('before') plus cedere ('to go'), the same cedere that strolls through 'proceed,' 'recede,' and 'exit.' So an ancestor is, quite literally, someone who went ahead of you. The '-ry' ending arrived later in English to gather all those forerunners into a single collective.
- shared origin
- Everyone alive shares a common ancestor 3,000 years ago
- math breaks
- 30 generations back needs more ancestors than humans ever existed
- pedigree collapse
- Inbreeding shrinks family trees back into themselves
- DNA fades
- Beyond 7 generations, some ancestors gave you nothing
- mitochondrial eve
- All humans trace to one woman, roughly 150,000 years ago
