DNA evidence has revealed that the oldest known common male ancestor is 340,000 years old, more than twice as old as previous estimates.
New Scientist reports that the sample comes from a recently deceased man named Albert Perry. After the African-American South Carolina man died, one of his relatives submitted a sample of his DNA to a company called Family Tree DNA for analysis.

All previously compared DNA samples pointed to a common Y chromosome traced back to man who lived between 60,000 and 140,000 years ago. But Perrys DNA sample broke the trend, not matching up with this common ancestor.
"It's a cool discovery," Jon Wilkins of the Ronin Institute in Montclair, N.J., told New Scientist. "We geneticists have been looking at Y chromosomes about as long as we've been looking at anything. Changing where the root of the Y-chromosome tree is at this point is extremely surprising."
After the initial tests on Perrys DNA, geneticists at the University of Arizona conducted further tests to confirm the anomaly. The Y chromosome in Perrys test matched up with those of 11 men who all lived in one village in Cameroon.
University of Arizona researcher Michael Hammer says Perrys DNA suggests there may have been an earlier species of humans that went extinctbut not before interbreeding with the more modern version of man.

The father of all men is 340,000 years old
"Perry did not descend from the genetic Adam. In fact, his Y chromosome was so distinct that his male lineage probably separated from all others about 338,000 years ago."

Didn’t match the oldest human ancestor? Mus be descended from apes and pigs...
Whodda thunk that some guy from South Carolina would prove that men have been around for 340,000 years. It’s a strange world we live in these days.
So before that they were all women?
Or all men.
Well, to track Female progenitors,
one would characterize mitochondrial DNA
You don't get that from dear ol' Dad
“When I was young, we had nothing but pinups of Helen Thomas. And we liked it!”
That’s funny
There seems to be 140,000 years difference. Could this Y-Adam be linked to Neanderthals or as Genesis describes, the Giants of old, men of renown.
You poor old man, what I had was Gidget
I bet he chased women, smoked cigars and drank whiskey every day of his life too!
And he didn't have a father?
immaculate conception?
I think it has to do with Y chromosome DNA, since that’s what’s passed on from father to son.
Mitochondrial Eve is through the DNA in the Mitochondria.
There must me something there in the woodpile.....maybe this thing:
Green Lizard Man of South Carolina
"I looked back and saw something running across the field towards me. It was about 25 yards away and I saw red eyes glowing. I ran into the car and as I locked it, the thing grabbed the door handle. I could see him from the neck down the three big fingers, long black nails and green rough skin. It was strong and angry. I looked in my mirror and saw a blur of green running. I could see his toes and then he jumped on the roof of my car. I thought I heard a grunt and then I could see his fingers through the front windshield, where they curled around on the roof. I sped up and swerved to shake the creature off."

“I get no respect I tell ya’’. “You know you’re old when your kids talk about ya right in front of ya’’. “What are we gonna do with Pop, Pop can’t stay here’’ “Mean while Pop’s in the corner drooling’’. No respect I tell ya.’
I wonder what Mr. Albert Perry looked like?
I’m sorry but Pop’s gotta go. I’ve been listening to him tell me I’ll never amount to anything for the last 339,940 years and enough is enough! I’ll get a job when I’m ready to.
This thread is killing me.
That didn’t take long.
Oddly worded, yet bizarre association
Bad reporting.
Every man now living on earth is descended from this individual male who lived 340,000 years ago. Of course he had parents, grandparents,uncles, cousins and lots of other relatives. But the descendants of all of his uncles and brothers have died out by now. (I'm sure in your family tree there are collateral relatives who either died without children or whose children have no descendants living now.) He is the last, not the first, common ancestor of modern humanity.
We only have a minuscule percentage of the puzzle pieces on the table.
There are a lot of pieces between this guy and any of the known founding Eves.
We know roughly where the pieces need to be to put the puzzle together, but we also know there are a lot of blank places on the table, we know the missing pieces are scattered in various boxes in the attic, the basement, next door and that well over half of them got lost in various moves from here to there.
We know it’s a family portrait, we have a vague idea of the background, we don’t know exactly which family members sat for the portrait, and there are enough puzzle pieces in the boxes to make a couple dozen portraits, landscapes, pictures of trains and Parisian cafés.
Other than that, it’s a simple matter of putting the puzzle together...
Oh, please.
The pieces are buried in backyards. Random backyards. All over town. And no one thought to mark the locations at the time of burial.
That too.
It still doesn’t explain why there are gaps between the pieces we do have now does it???
Apparently, science hasn’t learned enough to know they ain’t seen nuthin’ yet.
ROTFL!!!
LOL
I guess I could “stair” at the sun instead.
Thanks for the help.
They never cease to amaze, these 'scientists.'
Truth is, man has only been on this earth for a little over 4000 years - per a book called the Bible.
First thing I thought of when I read this.
“Father of all humankind is 340,000 years old”
So who is he, Connor MacLeod? Suppose they mean he lived 340,000 years ago, not that he’s that old?
Is the author suggesting there was an intermediate progenitorto NOT include Neandertal?
No immaculate conception at all. It just means that the descendants of any other male humans perished without contributing their Y-chromosome to any of the males in today’s world. All present males have inherited the Y-chromosome of this single human male who lived in the distant past. The date is surmised by relationships to surviving DNA and time periods required to accumulate changes in the genes due to natural causes over time.
Aarrg, my eyes.
Just imagine all the civilizations that could have arisen, fallen, and all remains disappeared it that time frame (our current civilization is at best only 6K old, although Hindu literature would put that date back an additional 16K).
If each civilization lasted just 10K and it took an additional 10K for all remains to subsume to Nature, then dividing by 20 we get something like 17 prior civilizations. No need for Aliens to explain the oddities and anomalies found in various places.
Humans (but not necessarily Homo sapiens) have been around for millions of years.
What happened here is what another poster said above. The male chromosome is lost whenever a man does not have sons. So, in a small population (as humans were that long ago), it is conceivable that there is only one unbroken line of male ancestry. As the population grows larger, with more males carrying that variant of the Y chromosome, the chances of that specific chromosome surviving are greater; other Y chromosomes have a larger chance of disappearing.
This story is a bit misleading. The ancestor 340K years ago is not the source of Y chromosomes for the entire population. That specific Y variant only exists in one village in Africa. All other men tested have a newer Y chromosome variant from an ancestor who lived around 200K years ago. I wouldn't be surprised if other families with variant Y chromosomes are found as time goes on. We are still a long way from knowing the genome of every single person, or even a statistically relevant number of people.
Or ‘we are still a long way’ from knowing just how little of what we think we know is actually true.
I'll be the first one to tell you that we barely know anything, and I'm a scientist.
What does it suggest about the history of a wrecked car when the 'car'cass is in Los Angels and in the glove box are gas station receipts from NYC, a later one from Cleveland, and a still later one from Tulsa?
Can you determine with certainty from this that the car passed through Phoenix or Las Vegas or Reno?
New headline: Missing Link Discovered in South Carolina!
So this guy might have lived to 350,200 years if he had just cut back on strips of bacon.

Thanks haffast.After the African-American South Carolina man died, one of his relatives submitted a sample of his DNA to a company called Family Tree DNA for analysis... All previously compared DNA samples pointed to a common Y chromosome traced back to man who lived between 60,000 and 140,000 years ago. But Perrys DNA sample broke the trend, not matching up with this common ancestor.It means that the earlier studies suffered from severe constraints of data. |

University of Arizona researcher Michael Hammer says Perrys DNA suggests there may have been an earlier species of humans that went extinct...No, it shows, once again, that the reason for apparent greater genetic variability in Africa isn't due to it being the oldest, it shows that populations are genetically narrowed by isolation.
The Neandertal Enigma"Frayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]

Hard times for sure.
Bingo!
Bacon DNA isn't that old.
