This video explains the difference between genetic and genealogical descent, showing why most of our genetic ancestry is lost over a short number of generations.

Can't wait until the "exactly one quarter of each of your grandparents" nitwit gets here.
Although in some families...
No, we ascend.
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.
It’s not a premise, it’s a fact. And yes, if that ancestor hadn’t had at least one descendant, it’s game over.
Fascinating how genetic material and the integrity of the genome overall are fully susceptible to the effects of entropy, yet many continue to believe the myth which claims that the process of molecular biology produces better and better products of those genes.
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.)
Yeah, prior to DNA testing, documentation is all we had, and even when there's a marriage record, not everyone is a fanatic about that. Also, I've found that other people doing the same lines find stuff I'd never heard of before (one of the sibs was born to the second wife, who only lasted a year before my grandcestor was widowed a second time), and there's also even less savory events that didn't get recorded. One of my cousins ran into a foundling ancestor who was a young child sitting crying on a late middle ages battlefield, and someone from the winning side scooped him up and raised him as his own.
Genealogists now add DNA matching to their profiles. It's very accurate. And yes, it does expose women who were being dishonest.
One thing always missing from these family tree diagrams is the mailman, or the milk man, or the traveling salesman.
Infidelity was just as present then, as now.
The “Ship of Theseus” conundrum.

DNA is not genealogy.
I don’t know how they do that DNA testing, but I’ve heard people say it often isn’t accurate.
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.
I’m talking about people who flaunt their genealogy going back hundreds of years, and think it makes them ‘special’.
It’s only as special as the culture that has been passed down to them. That is real.
Yes.
How do you know its true?
My Mother got me stared and I computerized all her records.
My sources for genealogy include census data combined with birth, death, and marriage certificates, divorce decrees, WWI and WWII draft cards, newspaper clippings of engagements, marriage, birth announcements, obituaries, cemetery records, and personal histories related by family members. I manage my data in Family Tree Maker and maintain a family tree on Ancestry.com. My resources include Newspapers.com, Findagrave.com, and a small library of books I’ve collected over the years. You cross reference everything.
It addictive and I’m meeting lots of family members in my retirement years.
