- Called upon at the last moment to deliver a talk at Humanists UK Convention 2023, Adam Rutherford stepped in and delivered a barnstormer.
Join Dr Adam Rutherford on a rip-roaring tour through human history (and beyond), with a brief detour via 'Who do you think you are?', and find out why we might all have more in common than we think.

This was fantastic on the day, and just the thing to keep me awake after two late and raucous nights in Liverpool, and it was wonderful to revisit on TH-cam today.
Thanks!
ADAM. it's "TEARS IN RAIN". From Blade Runner.
I wish I could write half the presentation you did whilst drunk at 2am.
I have read and enjoyed your books but I must say your speech was even better. Thank you.
Great presentation. the video would have been great if the slides were edited into the video or the projection screen zoomed in as they are hardly legible.
Brilliant 🙏
The spit-in-a-cup-now-tell-me-who-I-am folks drive me nuts. But at least you allowed me to laugh at it. And *oh, how I need to.* 😂
Adam Rutherford does a great job explaining why we may individually not have any DNA at all from humanity's most recent common ancestor. (MRCA)
People in present-day Peru might have 10,000 common ancestors who were living at the time of the MRCA. (Obviously, that number is for illustrative purposes only)
First Nations Australians might have 10,000 common ancestors who were living at the time of the MRCA.
Obviously one person is on both lists of ancestors, as they all had a common ancestor.
What are the chances that that one person's DNA dominates the other inherited DNA of the other 9,999 ancestors in present-day Peru and dominates the other 9,999 ancestors in present-day First Nations Australia?
Genealogy is not genetics. I can be descended from one person and not have inherited any of that person's DNA. After all, I have literally millions of ancestors and I can't inherit DNA from all of them.
Also, the most recent common ancestor keeps changing. The MRCA of people alive today is not the MRCA of people living 1500 years ago. There is nothing special about the MRCA. He or she is not the progenitor of the human race.
How incredibly high-minded and woke to make fun of caucasians. 125 years from now, people will watch this and laugh at how much he thought he really knew, repeat, repeat...
Your views are very narrow & you obtusely avoid the million years of intermingling of genetic code, including European history.. he pokes fun at inbreeding of royal dynasties. Your prejudices have blinded you.
@@PhilWhelanNow Yes, Adam Rutherford does a great job of explaining that the genetic isopoint means that all Europeans are descended from First Nations Australians.
You do make an excellent point about how common ancestry in a small geographical area (ie inbreeding) can produce genetic effects which can be easily detected.
