David Reich - Ancient DNA and the New Science of the Human Past (March 3, 2021)

This is the biggest new knowledge I have encountered since I graduated from my university in 1989! I am sure people like prof. Reich will keep adding new details. I cannot thank enough!

Philology is now considered interdisciplinary, but was essentially the parent discipline of linguistics, semiotics, and cultural anthropology.

I've spent the entire weekend watching videos like this one. I'm utterly, completely fascinated. These amazing things have come along a little too late for me to get in on them, but if I'd bumped into this when I was younger it would have immediately sucked me in. It's my kind of stuff.

Now for the three hours of study time 🤷‍♀️ that goes with every one hour lecture… 🔥 i’m cooking on all burners now🧬 Thanks for the update you guys rock

Thank you, Dr. Reich. We are like children listening to a great teacher. Harvard should give you everything you request. Long ago I dated a girl who received a MA from Harvard in Paranormal Science. Academia is prone to trends, like all cultural groups, especially the soft sciences. Follow the facts, revealing the facts of past populations increases our understanding of many things.

Super interesting lecture! Thank you!

The amount of new information is astounding.

Very nice lecture. Thank you.

DNA is incredible! We are going to be able confirm history a lot more.

This DNA is Changing every year, we are finding Burials with DNA which is now even more complex in Britain, we now know that the Original Builders of Stonehenge still exist in Britain in the West of Wales the DNA is Ancient going back longer than 6000 Years our Language is the only intact Celtic Language , Celts in Wales and Ireland are close in DNA terms, also in Language , many Ancient Stories talk of a Great Land to the West of Ireland and Wales that was lost to the Atlantic around 10, 000 years ago, there may well have been a further DNA in that area. I was used in the DNA use of the Stonehenge Skeletons, I have DNA which comes from Ceredigion West Wales or Cymru its correct name, we were the Ancient Britons, our Language gives the name to many parts of Britain. it is now proved by DNA that Stonehenge was built by people whose DNA still exists like mine in Ceredigion and Dyfed, the Stones Bluestones were taken from West Wales to Wiltshire about 5.5 thousand Years ago from the Presli mountains in West Wales, there are Blue Standing Stones Avenue like from there to Stonehenge many Megaliths and Tombs are dotted all over the Welsh Countryside and in what was our lands taken by the Saxon and the Scots , I am now 104 I speak a Language that was spoken before the time of Christ and it is still spoken, today, I think that DNA is more complex than just Charts and obviously there are always outliers, I have no English Blood in my body and my DNA is linked only in my terms to the British Isles and Ireland, I am 104 I was 6ft3" Tall when in the army during the War Blond Haired and Blue eyed , I looked more German than the Germans yet I am a Brythonic Celt both my parents were married in Ceredigion and their parents the same, we are able to trace our Ancestry at Least 800 Years in that area. Great Programme and great to listen to. I hope I live long enough to here more of your excellent work. I think I met Mr Paabo some time ago, but I thought he was Finnish. Nos da oes gwelwch yn dda.

Extremely knowledgeable I like how he loses his accent when he gets serious.

Dividing this presentation into ten lectures could be more effective in presenting such massive amount of information.

I love learning about this. 😍

Very interesting lecture.

Does anyone have any information about the event he mentions at 1:03:13? The rise in farmer ancestry in England?

At 48:50 where David Reich explains that the farmer population that built Stonehenge (no step ancestry) is replaced by 90% with a new population that resembles Modern Britain, i feel has vindicated the work of Gerald Massey and David Macritchie 'Ancient & Modern Britain' where they postulated these arguments in the 19th century.

Apparently Reich includes people from the Andaman Islands along with Southern Indians. This greatly exaggerates the genetic differences between people from the Northern and Southern sections of the Indian Subcontinent

Cheddar Man and WHGs were not as dark as SSAs. Vitamin D absorption would have been vital at those latitudes, especially after the last ice age. Also, a recent paper seems to indicate blue eyes, which all WHGs had, was an adaption to low light levels.

Truly fascinating. Explains so much, and thanks for mentioning Maria Gimbutas who taught at UCLA back when I was a student.

I would like to see DNA population drift and mixing simulations run with lots of different scenarios before I would even consider whether these models of migration and mixing are potentially valid. I mean, I would need to see someone put together 3 populations and model tons of scenarios of mixing and migration checking if the statistical methods mentioned in this video would correctly uncover each particular scenarios modeled before I would accept the methods as valid on real DNA data.
