Irish Origins | The Genetic History of Ireland

SUPPORT the Barksdale Family and History Channel BELOW!

The archaeological record of humans in Ireland begins in Castlepook Cave, County Clare, near the coastal city of Cork on the south coast. Here, a reindeer’s femur has been discovered that radiocarbon dating has identified as 33,000 years old. Initially excavated over a hundred years ago by the naturalist Richard Usher from a place he called Mammoth Cave (due to the abundance of mammoth bones found there) between 1904 and 1912, the reindeer bone was recently reexamined with modern techniques and technology and found to possess clear signs of butchery. It is the earliest specimen indicating human habitation in Ireland. But it doesn’t prove continuous habitation. Sea levels have changed dramatically over the eons, at times exposing land bridges to the British Isles that early migrants may have crossed only seasonally. Others might have been able to access the Irish shorelines in boats when the seas were far more shallow. Later immigrants almost certainly came in waves from the north and east and south, adding layer upon layer to the societies and cultures that already existed there.

This is a bit confusing - "Who populated Ireland and how they interacted with the people already there". Seems as though the "people already there" would be the people who populated Ireland.

It is a big pity Irish researchers have not taken into account North Spain and Portugal chromosomal and mitochondrial DNA as there have been strong population links between the islands and the Iberian Peninsula since the Neolithic period.

Indeed God Bless the Irish people...ALL OVER THE WORLD!!

My father was born in Tipperary and my mother was English. When I lived in County Cork for seven years and told my Irish friends of this background, they said I was "Half Irish and half Daft! "

I'm an Irish descendant and my maternal haplo group is from the middle east. My great grandmother's family on my mother's side is Irish, Scottish, and English.

I am Portuguese and in my DNA test found I am Irish, Scottish, and Welsh. I also have North African as well. It was no surprise to me my grandma had red hair. She was very Celtic.

My mother was from County Cork and my father from Kildare beautiful county!

This was very informative and enlightening. Especially grabbing my attention at 4:00 all the way through the ending.

I was one of the original contributors to the Irish DNA Atlas Project. There is an error however when they mention that there were only 196 contributors, the correct amount was 396.

It would be interesting to also take DNA samples of the descendants of the Irish prisoners who were sent to Barbados. I imagine that would add much to their records.

Genetic studies in Iceland reveal about 19% of the males and 62% of the females have Irish/British Isles DNA. Males are 80% and women are 37% Norwegian. There are many names of people and places in Iceland that derive from our Irish ancestry.

The atlas helped doctors work out how I got my genetic blood clotting disorder. The effected gene is most common in Scandinavian populations. The atlas is an invaluable resource. I highly recommend taking a look.

[terrioestreich]

I am so interested in this subject because I have ancestors from Ireland but this guy could have made it more understandable for us that haven't been educated in genealogy

[brawndothethirstmutilator]

This was a very interesting and thorough presentation. I recently found out I have genetic markers associated with Cork, Kerry and Limerick. This helped me to understand how they are identifiable and why they may have been insular in the more remote history.

[bluemallardduck]

Fascinating read. I think
that the genetic engineering of this world has given us a new understanding of we all arrived here.😊

[beautyhealthyhahaha]

your video is definitely a high quality academic research to a foreigner like me, who knew less. I wish I could travel Ireland somedays, your narration is fabulous,

[Treklosopher]

Still here to support Nick. Go Nick go! You can do this.
