Where could the Picts in Scotland had come from?

The idea that the Picts descended from an aboriginal bronze age/neolithic tribe is an old one, much bandied about by fiction authors in the 70's/80's.

However, there is a problem with this idea--although you are right about the dna having matches to the western Atlantic seaboard, this is not just true of the Picts, but about 75% of all Scots, 90% of the Welsh, 80% of the Cornish, about 88% of the Irish (nearly 100% in the West of the country), and is well over 60% in so-called Anglo-Saxon England!

there is NO hard evidence that picts spoke an non-Indo-European language; in fact, the recorded names of their kings and other names in Pictish areas of Scotland are Brythonic...like Welsh. The misunderstanding came through the Gaelic-speaking invaders, the Scotti of Ireland), who could not understand them...the two languages are both celtic (which has nothing to do with Germanic btw--in fact its closer to Italic!) but are not mutually intelligible!

Gradually the Picts were absorbed into the greater mass of invading people, just as it would seem the Britons in England were eventually absorbed into Anglo-Saxon culture.

Also, although it is true that the Scotti invaded Scotland, changing its language, there was no 'celtic invasion' into Britain/Ireland in the Iron Age! This idea that the British Isles peoples were 'celts' dates only from the 1700's!

Basically, the vast majority of Britons, but especially those in the so-called celtic areas are the descendants of bronze age, neolithic and, yes, even mesolithic people! It is actually now thought that the celtic languages themselves arrived in some primitive form no later than the the bronze age, if not slightly before!

+the red hair in neanderthals was caused by a totally different gene to that in modern humans! The small % of neanderthal dna all Causasians/Asians carry is dormant anyway.

Your assumption about the Picts is totally wrong.

The Picts were so called, because, that's what the Romans called them. The "ones with painted faces." Pict, a latin word which has given rise to the now modern English word, Picture.

The Picts belong to the Insular Celts. The Insular Celts are a combination of Northern European and Iberian peoples. That is a genetic fact. Why? How is that possible?

All around the British Coast, there is archaeological evidence which shows human settlements dating back over 10,000 years. These settlements are now under several feet of water.

The English Channel was no more than a stream, the North Sea was virtually nonexistent and the River Thames was a tributary of the Rhine. However, even when sea levels rose to cut off Britain from Continental Europe, tribal people still continued to migrate and trade.

Here is an interesting fact. When the pharaoh Sneferu achieved his goal of building the first true pyramid, the Red Pyramid, it was achieved using chisels made from copper that was mined from the British mainland.

My point is that the Ancient Peoples of Egypt, Carthage, Rome, Hittites, Greeks, Phonecian's have known about and travelled to and from the British Isles for a very long time.

Over the thousands years of human settlement, Picts are just another tribal people that forgot their roots.

The Picts have been a Celtic human beings concept to have originated in eire. Following a chain of campaigns in Scotland via Septimius Severus interior the early third century advert against the Caledones, their inhabitants became so critically depleted that they've been replaced via the Picts.

They came from the inventive imagination of Roman scribes, no group of people called themselves the Picts, there is absolutely no evidence to say the Gaels first turned up in what today we call Ireland, archaeology tells how far they spread, even as far as Iceland but not where they came from nor the date or place they took up residence in these Isles. There is no short answer but there is an abundance of National foundation myths and storytelling based on rehashed Roman texts.

the same place as the majority of people in Britain and Ireland originally come from, Iberia. The Picts were probably fairly similar genetically to the Gaelic tribes who would conquer them, the big difference was in culture/language, the Picts were probably Brythonic Celts while the Gaels were Goidelic Celts.

You could well be correct in your assumption , the Picts were an ancient Northern British people , by about AD 900 , they had effectively disappeared , probably assimilated with the Scots , their language was extinct by around the 10th century

"In Ireland and Scotland there are many jet black haired, some quite swarthy. There are also, conversely, many redheads."

I completely disagree with these statements

My understanding from ancient history is the Picts were a nomadic people from Scythia which is Russia however it depends on which books you read.................

Apart from the pictish stones at Aberlemno Meigle and forres there is no written history but I think you may be right, but then no one knows for sure
