I grew up in a family where genealogy was a very big deal. I’ve always thought it was kind of silly - how do you know it’s true? It seemed to me that it’s only ever as true as the women were honest.
The culture and tradition that are passed down aren’t ‘silly’ at all, though.
Interesting premise, but remove any one of the progenitors and the given descendent will not exist.
Never mind, Nikos. People drop out, don't they.
The same with bands. Original members drop out but then new ones join up.
Approximately 10--15% of USS Constitution is original to the warship’s 1794--1797 building period. Found below the waterline, the original material which has served “Old Ironsides” for over 225 years consists of the live oak vertical framing and the exterior white oak horizontal planking. (The interior, below-the-waterline planking was replaced many times over the warship’s long career, most recently in different twentieth century restorations.)
I saw this before. Not bad. I enjoyed it.
As far as the title, yes we do descend from all of our ancestors. By definition.
But he’s making the point that after a given number of generations we won’t have any DNA sequence left in our chromosomes from distant ancestors.
It’s just math.
