Human Movement The early Homo Sapiens

Just watched the YT clip on this

The thought that came to me was is it related to the Stone of Scone

Good thought, it could be, easy to check out if they are they are the same type of stone. Mind you it's a wee little pebble compared to the altar stone. Our ancestors certainly had a penchant for special rocks.
My friend Peter, the paleoartist suggested the Pleistocene glaciation could have moved it. Stones moved like this have a great name, glacial erratics. Being an ignoramus about geology I had too check if stones this big can be moved by glaciation - they can. The various waves of Pleistocene glaciation did cover Scotland and Britain, so it's a plausible theory.

They mentioned this in the clip - apparently there are no visible glacier trails

As to the truth of that I cant say

Actually scratch that Scone theory - Stone of Scone is red sandstone and the Altar Stone is bluestone

Good investigative work.

Norwegian Vikings were more violent than the Danes and seemingly had a system with less central authority. This is different to the nationaL stereotypes today

Skeletal Studies Show Viking Age Norway was a Hyper-Violent Nation

The Vikings were known for their marauding ways, and have gained a reputation as ferocious warriors and conquerors.

The Conversation has a good article about the Denisovans. Gives an update on what is known, including some discussion about interbreeding with sapiens and Denisovan derived genes.

Their DNA survives in diverse populations across the world – but who were the Denisovans?

The discovery of a finger bone in a cave in Siberia some 15 years ago kicked off a race to unravel the mysteries of an entirely new group of humanoids.

Added - this is an interesting one from a few years ago about the discovery of a 'mixed race' Neanderthal/Denisovan lass.

Meet Denny, the ancient mixed-heritage mystery girl

After the unearthing of a Neanderthal-Denisovan fossil, UK scientists are using groundbreaking techniques to learn more of the species’ complex bonds with humans

So I ask folks, do different species in the wild cross bred and produce fertile offspring? No they don't, because if they did they would be regarded as one species. So Neanderthals, Denisovans and us should be regarded as one species. Time to end sapiens bias.

From the muddy shoreline of Lake Turkana in Kenya, scientists found tracks of two hominids, Homo erectus and Paranthropus boisei, the first our likely ancestor and the other a more distant relative. It's the first evidence these hominids coexisted. The human tree was once bushy but has been pared back to just us. This article, by one of the authors appeared in the Conversation.

Fossilized footprints reveal 2 extinct hominin species living side by side 1.5 million years ago

Ancient fossil footprints are the first evidence of two different hominin species − Homo erectus and Paranthropus boisei − living in the same place at the same time.

Scientists have been able to pin down the last period of Neanderthal gene flow to modern humans, starting about 50,500 years ago and lasting about 7,000 years, after which the Neanderthals began to disappear. Make what you want out of that. The only evidence is the 1% and 2% Neanderthal genes present in Eurasian people today.

Neanderthal-human interbreeding lasted 7,000 years, new study reveals

A new analysis of DNA from ancient modern humans (Homo sapiens) in Europe and Asia has determined, more precisely than ever, the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,000 years—until Neanderthals began to disappear.

This article suggests a reason why the homo family formed species far quicker than other large vertebrates. I need to think about this one a bit but it may prove the old quote I keep repeating, 'technology changes the rules'.

How Our Human Lineage Broke All the Rules of Vertebrate Evolution

New study challenges traditional views on human evolution with "bizarre" findings.
