Where do you come from?

We do not “come into” this world; we come out of it, as leaves from a tree. As the ocean “waves,” the Universe 'peoples.' Every individual is an expression of the whole realm of Nature, a unique action of the total Universe.
-Alan Watts

Inside all of us lies a hidden history, the story of an immense journey told by our DNA. Deoxyribonucleic Acid is the biochemical molecule at the heart of the reproduction of all life, plants as well as animals. And since the discovery of its structure in 1953, scientists have pieced together the epic narrative of how human beings populated our planet.

Where do you come from?

"Cuimhnichibh air na daoine bho'n d'thainig sibh." ("Remember the people whom you come from." -Old Gaelic Proverb)


Some years ago I was persuaded to do a yDNA test for genealogical reasons. The primary object was to validate a Garvie family tradition that the Garvies of Perthshire were indeed descendants of John Garbh Maclean of Coll. I was curious. What did my yDNA tell me about my own "long journey"?

Like countless generations before me, I have been consumed by the questions, "Where have I come from? Why am I here? Why now?" I have approached these questions in previous blogs but I felt it was time to tackle the topic again.

When I first read the introduction to Bill Bryson's, A Short History of Nearly Everything, I was transfixed reading the paragraph where he says...

"Not only have you been lucky enough to be attached since time immemorial to a favored evolutionary line, but you have also been extremely - make that miraculously - fortunate in your personal ancestry. Consider the fact that for 3.8 billion years, a period of time older than the mountains and rivers and oceans, every one of you forebears on both sides has been attractive enough to find a mate, healthy enough to reproduce, and sufficiently blessed by fate and circumstances to live long enough to do so. Not one of your pertinent ancestors was squashed, devoured, drowned, starved, stuck fast, untimely wounded, or otherwise deflected from its life's quest of delivering a tiny charge of genetic material to the right partner at the right moment in order to perpetuate the only possible sequence of hereditary combinations that could result - eventually, astoundingly, and all to briefly - in you."

I don't think anybody has said it better than that! Hence my interest in my ancestry and genealogy.

Close Genealogy
This much I knew of my paternal line with a certain degree of confidence: I was born in Ladysmith, Natal South Africa. My father was born in Johannesburg. His father, my grandfather, in Knysna. His father, my great grandfather, came from Aberdalgie in Perthshire, Scotland. His ancestors in turn, I learnt, came from Perth, Kinnoull, and Scone. The further back I went in time the more did my ancestral history merge into tradition and legend and increasingly, the mists of myth.


Perthshire tradition had it that the Garvies were descended from John Garbh, seventh MacLean of Coll, through one of his sons, probably John of Totronald.   This son was wounded at the Battle of Inverkeithing in 1651, and did not return to Coll. His three sons (or grandsons) rented Upper Balgarvie, Lower Balgarvie, and Mill of Balgarvie in the parish of Scone, Perthshire from the Earl of Mansfield. Their descendants were tenants of Muirtown, Haggis Hall and several other farms near Perth.
(According to a letter from J C Garvie Macleod to the editor  of  the Oban Times, Spenthorn, West Park, Leeds. Date unknown. Also see A E Garvie, Memories and Meanings of My Life, 15.)

In Agents of Change, Scots in Poland 1800-1918 by Mona Kedslie McLeod (Tuckwell Press ISN#1 86232 081 0 ) page 116 we find...

"The Garvie brothers were descended from the Macleans of Coll. Backing the wrong side in the first Jacobite Rising of 1689, they forfeited their lands, adopted their nickname 'garbh', the Gaelic for rough or strong, and moved to Perthshire in search of a living. By the end of the eighteenth century Perth had become one of the centres of the developing linen industry and was enjoying a building boom..."

To date I had not found historical genealogical records to confirm this. I still wanted to know where I came from! So I resorted to DNA analysis. My yDNA Haplogroup turned out to be: R-M207 Subgroup: R1b1b2-M269


Y-chromosome DNA (yDNA) is a type of DNA that is only carried by men and is inherited directly from their fathers. Men who share a common paternal ancestor will have virtually the same yDNA, even if that male ancestor lived many generations ago. Theoretically then, sooner or later, as more data becomes available and more matches come to light I should be able to deduce whether there are Garvie links to the Hebrides and specifically to the Isle of Coll or not. Was it just accident that in a way I had come geographically full cycle and now stay where the last of the lairds of Coll died?...

Coll was home to a branch of the Clan Maclean for 500 years, not all of which were peaceful. In 1590 the Macleans of Duart invaded their cousins on Coll with the intention of taking the island for themselves. A battle was fought at Breachacha Castle where the Coll clan overwhelmed the Duarts, chopped off their heads and threw them in the stream, which is still known as "the stream of the heads". The Macleans of Coll retained their baronial fief and Castle of Breachacha until 1848 when Alexander Maclean of Coll emigrated to Natal, South Africa where he died unmarried.

This more distant biological journey in time is as interesting and fascinating as that of my immediate documented ancestry. We carry within us the genetic material and possibly coded memories that go back to creation itself!

Deep Genealogy
When the last Ice Age began to abate ~13,000 years ago and living conditions slowly improved across Europe, localized populations migrated from west Asia R1b1b2-M269 moved primarily throughout western Europe, creating opposite geographic distributions which are still evident today. R1b1b2-M269 is found at very high frequencies (50-80%) throughout western Europe particularly the Celtic populations in Ireland, Wales, and Scotland, especially the Hebrides. Geneticists are pretty sure about the broad details of this remarkable migration of Celts. It is reasonably well documented for instance in Wikipedia: http://en.wikipedia.org/wiki/Haplogroup_R1b_(Y-DNA) and http://en.wikipedia.org/wiki/Haplogroup_R1b_(Y-DNA)#R1b1a2_.28R-M269.29

Even Deeper Genealogy
Haplogroup R is defined by a DNA marker known as M207. Everyone who carries this marker today descends from a common paternal ancestor who lived about 30,000 years ago in west Asia. To date, over thirty subclades of haplogroup R have been identified, of which, R1a1-M17 and R1b1b2-M269 (historically called R1b3) are the most well described. Both of these subgroups are indicators of European ancestry with haplogroup R1a1-M17 most representative of Eastern Europeans and R1b1b2-M269 most characteristic of Western Europeans. Originating in the regions of modern day Turkey I saw correlations with the Keltoi and the diaspora of nations alluded to in Genesis and Josephus.

From Wikipedia, the free encyclopedia

Further back, as members of the human family, all people living today can trace their earliest paternal ancestors to populations that lived approximately 100,000 years ago in eastern Africa and possibly southern Africa described as the "Cradle of Humankind"  where as providence had destined I would spend a number of years of my life working probing the night skies tracking spacecraft. These early humans became spread throughout the African continent, and beginning ~50,000 years ago, a series of complex migrations moved them out of Africa into regions of Asia and beyond to eventually populate every major area of the world.

Very Deep Genealogy
Some have suggested there might have been, startling as it may sound, an inter-galactic intervention at some time in the distant past or, possibly occurring all the time! Molecular biologists have been perplexed by segments of DNA that appear to be older than the Earth itself suggesting an origin beyond our Solar System.

Dr. Francis Crick,  Nobel Prize Winner and one of the discoverers of the DNA molecule suggests in his book, Life Itself: Its Origins and Nature (1981), that  primordial life was shipped to Earth in "spaceships" of some kind. Crick makes this startling proposition: "Life did not evolve first on Earth; a highly advanced civilization became threatened so they devised a way to pass on their existence. They genetically-modified their DNA and sent it out from their planet on bacteria or meteorites with the hope that it would collide with another planet. It did, and that's why we're here."

Terming his model "Directed Panspermia", Crick suggested that a "spaceship" carrying "large samples of... microorganisms" was sent to the Earth billions of years ago by an extraterrestrial civilisation - either as an experiment, preparation for colonisation or a genetic Noah’s Ark of some sort. (Crick, F. H. C., and Orgel, L. E. "Directed Panspermia", Icarus, 19, 341 (1973), quoted in David Darling’s Encyclopedia of Astrobiology, Astronomy, and Spaceflight)

Zecharia Sitchin, at the other extreme, suggests a much later Mesopotamian intervention based on his reading of Sumerian texts and the first eleven chapters of Genesis, speculating in his Divine Encounters: A Guide to Visions, Angels and Other Emissaries and elsewhere, that humans were biologically engineered about 6000 years ago. Sitchin's views, though no less extreme than Crick's, are generally disregarded by the scientific community but have become popular among the general public as evidenced by the unusual demand for his numerous writings.

Sumerian Version: Ningishzidda, Enki and Ninmah create Adamu

It is speculated by both rational scientists and mavericks that our DNA could be encoded with messages from these other civilizations. Ancestral memories par excellence, beyond our wildest dreams, could be encoded in our very DNA. Unknown cosmic entities may have programmed our genetic make-up so that when we reached a certain level of intelligence, we would be able to access this information, and they could therefore "teach" us about ourselves, and how to progress. (For more about so-called "Junk DNA" see http://en.wikipedia.org/wiki/Junk_DNA. On "DNA Activation" see http://arxiv.org/ftp/arxiv/papers/1303/1303.6739.pdf.)  Human DNA appears to be a lot more pliable (eg.  http://www.bbc.co.uk/news/science-environment-21091066) and mysterious (eg. the DNA Phantom Effect http://www.thescienceforum.com/biology/1144-dna-phantom-effect.html) than previously thought.

Though cautious in their conjectures and conclusions, exobiologists are now more and more convinced that not only could microorganisms proliferate throughout creation but that it is equally possible that actual alien life forms might have traveled from other worlds to Earth! The Universe could be teeming with life. Celestial life! Retired Senator John Glenn and former Astronaut once cryptically remarked...

Back in those glory days.... Some people asked....were you alone out there? We never gave the real answer, and yet we see things out there, strange things, but we know what we saw out there. And we couldn't really say anything. The bosses were really afraid of this, they were afraid of the War of the Worlds type stuff, and about panic in the streets. So we had to keep quiet. And now we only see these things in our nightmares or maybe in the movies, and some of them are pretty close to being the truth" (NBC TV 6th March 2001).

Potent words! Tongue in cheek? A Freudian slip? An intentional admission?  (See http://www.enterprisemission.com/glenn.htm) Or are we standing on the very Threshold of an exciting new era, the Kingdom of Heaven itself? I would not be surprised! In fact, we always have!

At times I had to tread
Where not a star was found
To lead or light me, overhead;
Nor footprint on the ground.

I toiled among the sands
And stumbled with my feet;
Or crawled and climbed with knees and hands,
Some future path to beat.

-Gerald Massey, The Natural Genesis.

Panspermia: The Mantis or the Stork?

Genomic analysis, based on increases in genome size and the evolutionary record, indicate that genes began to evolve and to undergo duplicative events billions of years before the formation of this planet, at least 10 billion years ago. This does not mean that life began 10 billion years ago, but rather that the first gene was fashioned approximately 6 billion years before the creation of Earth. The genetic evidence supports extra-terrestrial abiognesis... (p.12) ...the first gene was fashioned billions of years before the creation of Earth (p.19).
-Rhawn Joseph and N. Chandra Wickramasinghe, 
"Genetics Indicates Extra-terrestrial Origins for Life", Journal of Cosmology, 2011, Volume 16, 

Ironically, it was genealogy that led me to reflect on exobiology - the evolution of extraterrestrial life and its possible migration to Earth. And it wasn't simply the bizarre idea that the Hottentotsgot (the praying mantis) of my Khoi forbears, thought by some to have been a "Sky God", had genetically engineered us! Rather, it was a more sober, scientific pursuit that led me in this direction.

Family tradition maintained that the Garvies of Perthshire, Scotland were from somewhere else. A family oral tradition insisted that the Garvies were descended from John Garbh, seventh MacLean of Coll, through one of his sons. This son was wounded at the Battle of Inverkeithing in 1651, and did not return to Coll. His three sons (or grandsons) John, James and Patrick rented Upper Balgarvie, Lower Balgarvie, and Mill of Balgarvie in the parish of Scone. From them stemmed the Garvies of Perthshire where my great grandfather Laurance was born two centuries later.

To date I haven't found source documentation to substantiate this tradition. It is simply one of our many Garvie ancestral legends and now part of the corpus of Garvie mythology. In an attempt to verify this I then resorted to y-DNA analysis. I was hoping to find a genetic connection between the Garvies of Perthshire and the Macleans of Coll. Unfortunately no such proof has been found. We have far too few Garvie and Maclean DNA samples to confirm a genetic connection. All we can say at this stage is that both the Garvies and the Macleans share strong Celtic DNA material in common. We must still find the documentary and genetic "missing links" to solve this puzzle. But it was this conundrum that got me thinking about the bigger picture, the origin of life on planet Earth.

In recent years, astrophysicists have discovered a vast number of "extrasolar planets", "islands" in far flung Galactic Hebrides, that could and probably harbours life far beyond our wildest imaginings...
Extrasolar Planets
An extrasolar planet, or exoplanet, is a planet outside the Solar System we take for granted and imagine is extraordinarily unique.. As of November 23, 2011, some 704 extrasolar planets (in 578 planetary systems and 83 multiple-planet systems) have been identified.
A substantial fraction of stars have planetary systems - data from the HARPS mission indicates that this includes more than half of all Sun-like stars. Data from the Kepler mission has been used to estimate that there are at least 50 billion planets in our own galaxy.http://en.wikipedia.org/wiki/Extrasolar_planet
Unashamedly, Earthlings are searching for habitable planets that they could one day colonize! This archaic "colonial mentality", now projected on a cosmic scale, is to my mind, just a little too presumptuous. What if it happened the other way round, that instead, Earth had been colonized? There is a surprising proponent for this view. Dr Francis Crick, co-discoverer of the DNA-molecule and Nobel Prize Winner has suggested just this!

Panspermia 
Francis Harry Compton Crick OM FRS (8 June 1916 - 28 July 2004) was an English molecular biologist, biophysicist, and neuroscientist, and most noted for being one of two co-discoverers of the structure of the DNA molecule in 1953, together with James D. Watson. He, Watson and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
During the 1960s, Crick became concerned with the origins of the genetic code. In 1966, Crick took the place of Leslie Orgel at a meeting where Orgel was to talk about the origin of life. ..... Many molecular biologists were puzzled by the problem of the origin of a protein replicating system that is as complex as that which exists in organisms currently inhabiting Earth. In the early 1970s, Crick and Orgel further speculated about the possibility that the production of living systems from molecules may have been a very rare event in the universe, but once it had developed it could be spread by intelligent life forms using space travel technology, a process they called “Directed Panspermia”.
-http://en.wikipedia.org/wiki/Francis_Crick#Directed_panspermia
Dr. Francis Crick suggests in his book Life Itself: Its Origins and Nature (1981) that primordial life was shipped to Earth in "spaceships" of some kind. Crick makes this startling proposition: "Life did not evolve first on Earth; a highly advanced civilization became threatened so they devised a way to pass on their existence. They genetically-modified their DNA and sent it out from their planet on bacteria or meteorites with the hope that it would collide with another planet. It did, and that's why we're here."

Terming his model "Directed Panspermia", Crick suggested that a "spaceship" carrying "large samples of... microorganisms" was sent to the Earth billions of years ago by an extraterrestrial civilisation - either as an experiment, preparation for colonisation or a genetic Noah’s Ark of some sort. (Crick, F. H. C., and Orgel, L. E. "Directed Panspermia", Icarus, 19, 341 (1973), quoted in David Darling’s Encyclopedia of Astrobiology, Astronomy, and Spaceflight)

Dr Crick is not alone in these views. Sir Fred Hoyle in his Life from Space, took a similar view. He rejected chemical evolution in favour of propagation from space or panspermia. http://en.wikipedia.org/wiki/Fred_Hoyle#Rejection_of_chemical_evolution

It is speculated that our DNA was encoded with messages from that other civilization. They programmed the molecules so that when we reached a certain level of intelligence, we would be able to access their information, and they could therefore "teach" us about ourselves, and how to progress. (For more about so-called "Junk DNA" see http://en.wikipedia.org/wiki/Junk_DNA)  The Universe could be teeming with life.

Sumerian and other mythologies, even passages in the Bible, tantalise us with stories of our celestial origins. Crick and others have suggested there might be DNA evidence that could substantiate this. Just as Garvies suspect that their origins go back to the distant Isle of Coll so Earthlings infer they've come from some far away planetary island in the Cosmos! But our limited historic and genetic records continue to tease us.- had we been pollinated from afar?

Eccentric? Science Fiction? Till more evidence comes in, it may seem so. But we live with the "missing links" and the questions! To think that we already have all the answers is presumptuous to say the least. So the Khoikhoi idea of a Celestial Mantid, a Khoi Prometheus, that once gave their ancestors the gift of fire and their distinctive clicking language, might not be as far fetched as sceptics might think! Sober biologists and cosmologists are entertaining similar ideas.  And if not a Praying Mantis, then perhaps a Galactic Stork really did bring us, just as our parents taught us!

Deep Genealogy, DNA, and Ancient Celtic Histories

The Storms River Mouth Cave was very likely one of the shoreline abodes of some of my ancient stone age ancestors. Though I had never been there before, it was a very familiar place, a place of epiphanies like Elijah's cave. My roots in Africa are very real. It is equally real on other distant shores: Scotland, Ireland, going back even to the Black Sea! Once, sitting on a beach on Mull looking across to the sacred island Iona in the Hebrides there were the same familiar feelings that "this was home".

The reason for this excursion deep into my own personal history is simple. Calvin Miller in The Path of Celtic Prayer expresses it well, "I wanted to find the flame again. For it is sometimes by looking at the past that the present amends its dead soul, and there is a chance that the future is born with new vitality." (p.6)

To confirm these connections, I arranged a Y-Chromosome DNA analysis tracking my paternal line down time and back some 30,000 years into my own misty antiquity. The results were intriguing. This was a far deeper cave...

"Haplogroup R is defined by a DNA marker known as M207. Everyone who carries this marker today descends from a common paternal ancestor who lived about 30,000 years ago in west Asia. To date, over thirty subclades of haplogroup R have been identified, of which, R1a1-M17 and R1b1b2-M269 (historically called R1b3) are the most well described. Both of these subgroups are indicators of European ancestry with haplogroup R1a1-M17 most representative of Eastern Europeans and R1b1b2-M269 most characteristic of Western Europeans.

"R1b1b2-M269 is found at very high frequencies (50-80%) throughout western Europe particularly in the Ireland, Wales, Scotland, England, Portugal, France, Germany, and northern Italy, with diminishing frequencies towards the east although representation stretches as far as central Asia and India." (Genetree CGG Report)

R1b1b2 Celts is thought to have arrived in central and western Europe around 2300 BCE, by going up the Danube from the Black Sea coast. The migration must have been on a massive scale, maybe due to pressure from other Indo-European people from the north. There might have been several consecutive waves across the Black Sea to the Danube, but the largest one between 2500 BCE and 2300 BCE. From there they moved in Britain. http://www.eupedia.com/europe/origins_haplogroups_europe.shtml#R1b-subclades

That is genetic history and it is pretty technical but the romantic in me warms more to the stories of the bard, storyteller, and ancient historian. For instance, William Livingston writes in his 1850 Vindication of the Celtic Character ...

"The Celtic race were the first known inhabitants of Europe, which was occupied throughout by various tribes or clans. The appropriate name which this remarkable race gave themselves was Celtae; but the terms Galatae, Galatians and Galli, were appellations by which in later ages they were usually distinguished. They covered all Europe to the western extremities. The Keltoi inhabited to the farthest west. The Cymrig Gauls carried their arms along the Danube, Illyricum and Dalmatia. They took possession of the Alps, and colonized the whole north of Italy."

Livingston describes their spread across Europe challenging the Greek and Roman empires. He then links them, with reference to Josephus, to Biblical genealogy...

"Gomer was the father of the Gomarians who are now called by the Greeks, Gauls. Filii autem Japhet septem numerantur ex quo Galatae id est Galli.... Gomer, the eldest son of Japheth, and the father of the Gomarians, who anciently inhabited Galatia, Phrygia, &c. &c., either by the east end of the Euxine, or by crossing the Hellespont, penetrated into Europe, and peopled the countries now called Poland, Hungary, Germany, Switzerland, France, Spain, Portugal, Britain and Scandinavia. Gomer's sons settled themselves in Spain and Italy as early as 142 years after the flood.... they were contemporaries of Abraham and his father Terah.... Here is antiquity for you, equal to that of the ancient patriarchs. Nor do the ancient Scots or Irish appear of a different original. The Phoenicians, another branch of the Celts, inhabited the coast of the Red Sea."

Modern historians may well attribute much of that to fable, legend, mythology, and the imagination and yet there is a strange concurrence with the DNA record. White South Africans are acutely aware of how Genesis 10 and Josephus Bk 1, Ch 6 came to be misapplied to under gird our dubious racist doctrines. Discovering that I was also of Khoikhoi descent was a helpful corrective to any presumed supremest attitudes I might have entertained. Just as the Zulu and the Lemba take pride in their ancient traditions so I find my own origins both humbling and enriching.

Theseus in A Midsummer Night's Dream puts such romance down to fantasy and imagination...

I never may believe
These antique fables, nor these fairy toys.
Lovers and madmen have such seething brains,
Such shaping fantasies, that apprehend
More than cool reason ever comprehends.
The lunatic, the lover and the poet
Are of imagination all compact.
One sees more devils than vast hell can hold;
That is the madman. The lover, all as frantic,
Sees Helen's beauty in a brow of Egypt.
The poet's eye, in fine frenzy rolling,
Doth glance from heaven to earth, from earth to heaven;
And as imagination bodies forth
The forms of things unknown, the poet's pen
Turns them to shapes and gives to airy nothing
A local habitation and a name.
Such tricks hath strong imagination
That, if it would but apprehend some joy,
It comprehends some bringer of that joy.
      - William Shakespeare, "A Midsummer Night's Dream", V, I, 4-17

To which, with Hippolyta, I reply and point to a reality and a Joy far beyond the superficial joy of our sometimes mundane world:

But all the story of the night told over,
And all their minds transfigur'd so together.

...for I'm a romantic at heart. Caves and DNA, Celts and Khoikhoi fire the imagination, transfigures the mind.
