    Joining The Dots

    I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato’s own words, tempered with some critical thinking and a modicum of common sense.Read More »

Out of Africa

The Out of Africa theory is the dominant model of the geographic origin and early migration of anatomically modern humans (Homo sapiens)(a) . It arose from discoveries in East Africa less than a century ago. Previously, a more popular idea prevailed which claimed that modern humans arose from different populations of earlier hominids in various regions of the world. This regional development still has some advocates(h)(c).

A 2007 report deviated somewhat from the OoA concept, suggested that the first Europeans had arrived from Asia, rather from directly from Africa!(f)

While details of the OoA theory are continually being modified in the light of new discoveries, genetic studies have only strengthened support for the theory. The most recent genetic studies suggest that “a vast inland oasis in present-day northern Botswana was once home to the founder population of all modern humans.” (b)

New studies suggest that the early development of homo sapiens may have been more complex than previously thought(e). Chris Stringer, of the Natural History Museum, London, is quoted by The Guardian as saying that “the immediate predecessors of modern humans probably arose in Africa about 500,000 years ago and evolved into separate populations”.

It is still uncertain whether humans left Africa in two or more waves and when did they do so. Stephen Oppenheimer, who has written extensively on the subject, maintains that a single group of migrants were involved, around 80,000 years ago. He offers a number of papers on the Bradshaw Foundation website(d).

As I see it, dating the spread of humans remains unclear to a layman such as myself. Of particular interest is determining more accurately when man first crossed the Bering Strait from Asia into America.

>Not directly related to this subject but nevertheless interesting is a recent research report published in the Journal of Mediterranean Archaeology(g) (2021 DOI: 10.1558/jma.18784), which deals with Mediterranean migration trends over 8,000 years. It found that, within the region from about 7,500 BC to AD 500, migration rates ranged from about 6% to 9% of the population within the dataset. These rates seem to have decreased over time and “that despite evidence of cultural connections, there’s little evidence of massive migration across the region.”<

Sepehr, Robert

Robert Sepehr is an American author, producer and anthropologist. He Sepehrspecializes in linguistics, archaeology, and paleobiology.

Even more extreme are his ideas regarding a hollow or partially hollow Earth as expressed in his, Gods with Amnesia[1404].  Apart from promoting this silly idea, Sepehr’s book is claimed to contain an amount plagiarised material(b).

He is harshly critical of the ‘out-of-Africa’ theory as evidenced by blogs on his Atlantean Gardens website(a). Sepehr takes a hyperdiffusionist position and proposes that an ‘out-of-Atlantis’ hypothesis would be more appropriate, although he seems to be overly influenced by the writings of Blavatsky in this regard. For me, his site is unreliable, containing too much pseudoscience and speculation.



Ice Ages

Ice Ages have been a fact of life on Earth for aeons, according to conventional ice age theory. There is now evidence that during the very early existence of our planet, the entire Earth was completely glaciated, possibly twice!(w)

However, the exact cause of the onset of an ice age is still a matter of active debate. Ralph Ellis has now proposed a new theory based on a cyclical alteration of polar albedo by atmospheric dust(n).

Over the last three million years, a period referred to by geologists as the Pleistocene Epoch, at least thirty Ice Ages have been ‘identified’. The exact extent of the polar ice caps during the last Ice Age is the subject of some debate with new evidence from northern Sweden and Norway, suggesting a less extensive cap than previously believed. Various theories have been proposed to explain the onset and the ending of these Ice Ages ranging from changes in the earth’s orbit(g) around the sun to the effects of the Earth’s passage through the spiral arms of the Milky Way.

Over recent decades we have been consistently told that global warming is underway with a constant threat of rising sea levels. Consequently, it was no surprise when, in April 2018, The Guardian had a headline declaring that Glacier loss is accelerating because of global warming(r). However, an equally up-to-date website(s) claims that most of the worlds glaciers are actually growing and makes the comparable assertion that sea levels have stopped rising(t). Over a decade ago the well-known botanist David Bellamy made similar claims, that were refuted in a revealing article by George Monbiot, also in The Guardian(u).

Emilio Spedicato has proposed(a) that glaciations are started by asteroidal or cometary impacts on land and terminated by impacts with an ocean. The late Sir Fred Hoyle and his equally radical colleague Chandra Wickramasinghe concurred with this view. They believe that an impact of sufficient size would have vaporised and ejected billions of gallons of water into the upper atmosphere creating an immediate ‘greenhouse effect’ that then led to the melting of the glaciers.

Spedicato contends(z) that circa 9,600 BC, an impact in the Atlantic by an Apollo Object led to the demise of Atlantis, an idea similar to the earlier contention of Otto Muck.

The last Ice Age reached what is known as the Last Glacial Maximum (LGM) around 25,000 -15,000 BP, according to Ray & Adams(q). LGM describes the time when the glaciers reached their maximum extension.

Remarkably, the very existence of an Ice Age was only first conceived just over 150 years ago when Louis Agassiz first published his theory[002][003]. It took another century before it was fully realised that some of the consequences of the melting of the glaciers at the end of each Ice Age, would have been the flooding of continental shelves and the breaching of low-lying land bridges.

An example of such events would have been the submergence of the majority of the Celtic Shelf separating Britain and Ireland from mainland Europe. In the South China Sea large chunks of what is known as Sundaland were also flooded. At the eastern end of the Mediterranean the Bosporus was breached flooding the Black Sea and more controversially some claim that there had been a breach of a landbridge at the Strait of Gibraltar.

Prompted by the fact that the date given by Solon/Plato for the destruction, 9600 BC coincides with the retreating of the last Ice Age, all the above submergences and breaches have been included in the Atlantis debate.

New studies have shown interesting confirmation of the ‘Out of Africa’ theory, which had recently come under attack. The effects of the last Ice Age on the population of Europe were apparently quite dramatic(l).  In 2013, journalist, Paul Salopek set out on a 21,000 mile walking journey from East Africa, across Asia and down the west coast of the Americas in an attempt to emulate mankind’s long odyssey as he populated the planet(v).

The most recent genetic studies suggest that “a vast inland oasis in present-day northern Botswana was once home to the founder population of all modern humans.” (x)

A first-rate work[390] by Steven Mithen on the aftermath of the last Ice Age was recently published.

Fundamentalist Christians who believe in a literal seven days of creation have great difficulty with modern Ice Age theory(b) and some propose that an ice age occurred after the biblical Deluge(f) . Furthermore, it would be dishonest if I did not record that there have been more credible attempts to totally debunk(e) ‘conventional’ Ice Age Theory. The late Peter K. Bros (1939-2007) expressed such views in J. Douglas Kenyon’s Forbidden History[802.44]. Furthermore, Allan & Delair offer similar views in Chapter 12 of Part One of their acclaimed book Cataclysm[014] as does Richard E.Mooney[0842.87].

The Thunderbolts website has a forum(h) dealing with whether Ice Ages occurred at all! Those interested in this particular controversy will find some worthwhile comments there. The same site has linked to an article that offers further challenges to conventional Ice Age and global warming theories. This report(j) concerns the discovery of the remains of a 4,000-year-old forest in the Alps at the edge of a retreating glacier, which added further evidence that warmer climates than at present were experienced since the last Ice Age. A regular Thunderbolts contributor, Rens Van Der Sluijs, also deals with global warming during the last Ice Age as revealed through mythology(k). However, Thunderbolts ‘Electric Universe’ concept has also received some highly critical reviews(m).

An interesting side issue is the work of Genevieve von Petzinger(y) who has collated recurring geometric symbols found in the Ice Age caves and rock carvings, not only across Europe, but in Asia and less frequently in Africa and the Americas.

The University of Sheffield have now produced a set of maps showing the shrinkage of the last glacial ice sheet that covered most of the British Isles at the end of the last Ice Age(d). That particular ice sheet contained enough water to raise the world’s oceans by 2.5 metres when melted. Further maps have been published on Don Hitchcock’s website(i).

The retreating ice sheets also produced drumlins, with as many as 20,000 to be found in Ireland, with many of these and other Ice Age creations featuring in the placenames of my country(p).

For some fundamentalist Christians the (only) Ice Age lasted from around 2500 BC until 1500 BC(o).
