- 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 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.
A wonderful talk. Full marks for resilience after a boozy late night out.
ADAM. it's "TEARS IN RAIN". From Blade Runner.
This is a fascinating lecture. It's unfortunate the videographer wasn't up to the task. Shame on him/her. Prof. Rutherford was pointing out things on the slides while the videographer was more concerned about smoking a cig. Point of fact: 3:35 +
Be that as it may, this is a lecture well worthing watching.
I have read and enjoyed your books but I must say your speech was even better. Thank you.
I wish I could write half the presentation you did whilst drunk at 2am.
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.
When is the next convention
Is there a worldwide convention?
We're Humanists UK so all our events are in the UK, but the next Humanists International conference is in Singapore... at the end of this month!
@@HumanistsUK I would like to attend next year 2025
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.* 😂
Ask the-spit-in-a-cup people if somebody can spit in a cup and science can say what gender they are. Spoiler alert - science cannot tell you what gender you are.
Surely these calculations Rutherford is making would be massively complicated by the fact that peoples reproductive partners are conditioned by class, geography and various levels of inbreeding. These calculations assume an even spread of population. Most peoples ancestors will likely have been marrying forgotten third cousins who live in village next door and are of a similar level of wealth to themselves. Im sure the genes of the nobility would filter down in various ways but it wouldnt be the even spread that Rutherfords calculations imply
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.
