Honoring the Ancestors
 

The Elder's Eyes  by  Gilbert W. Whiteduck

Your piercing eyes challenge the circle
They reveal a pride so long born,
of today they are not
Formed of secrets and pain,
they do reveal
Fear of opening the cloak of silence
Rages behind the curtains
Remembering can hurt but does it heal
The eyes are the windows of the mind
The eyes are upon me
I bow my head in a retracted humbleness
The challenge is not in the words
Eyes can not answer
Years of many moons
The strength does here lie
Your piercing eyes do challenge
Your Elder eyes have here spoken.
 

Roots of Human Family Tree Are Shallow

Continued . . . But few people realize just how intricately that web connects them not just to people living on the planet today, but to everyone who ever lived.

With the help of a statistician, a computer scientist and a supercomputer, Olson has calculated just how interconnected the human family tree is. You would have to go back in time only 2,000 to 5,000 years–and probably on the low side of that range–to find somebody who could count every person alive today as a descendant.

Furthermore, Olson and his colleagues have found that if you go back a little farther–about 5,000 to 7,000 years ago–everybody living today has exactly the same set of ancestors. In other words, every person who was alive at that time is either an ancestor to all 6 billion people living today, or their line died out and they have no remaining descendants.

That revelation is "especially startling," statistician Jotun Hein of England's Oxford University wrote in a commentary on the research published by the journal Nature.

"Had you entered any village on Earth in around 3,000 B.C., the first person you would have met would probably be your ancestor," Hein marveled.

It also means that all of us have ancestors of every color and creed. Every Palestinian suicide bomber has Jews in his past. Every Sunni Muslim in Iraq is descended from at least one Shiite. And every Klansman's family has African roots.

How can this be?

It's simple math. Every person has two parents, four grandparents and eight great-grandparents. Keep doubling back through the generations–16, 32, 64, 128–and within a few hundred years you have thousands of ancestors.

It's nothing more than exponential growth combined with the facts of life. By the 15th century you've got a million ancestors. By the 13th you've got a billion. Sometime around the 9th century–just 40 generations ago–the number tops a trillion.

But wait. How could anybody–much less everybody–alive today have had a trillion ancestors living during the 9th century?

The answer is, they didn't. Imagine there was a man living 1,200 years ago whose daughter was your mother's 36th great-grandmother, and whose son was your father's 36th great-grandfather. That would put him on two branches on your family tree, one on your mother's side and one on your father's.

In fact, most of the people who lived 1,200 years ago appear not twice, but thousands of times on our family trees, because there were only 200 million people on Earth back then. Simple division–a trillion divided by 200 million–shows that on average each person back then would appear 5,000 times on the family tree of every single individual living today.

But things are never average. Many of the people who were alive in the year 800 never had children; they don't appear on anybody's family tree. Meanwhile, more prolific members of society would show up many more than 5,000 times on a lot of people's trees.

Keep going back in time, and there are fewer and fewer people available to put on more and more branches of the 6.5 billion family trees of people living today. It is mathematically inevitable that at some point, there will be a person who appears at least once on everybody's tree.

But don't stop there; keep going back. As the number of potential ancestors dwindles and the number of branches explodes there comes a time when every single person on Earth is an ancestor to all of us, except the ones who never had children or whose lines eventually died out.

And it wasn't all that long ago. When you walk through an exhibit of Ancient Egyptian art from the time of the pyramids, everything there was very likely created by one of your ancestors–every statue, every hieroglyph, every gold necklace. If there is a mummy lying in the center of the room, that person was almost certainly your ancestor, too.

It means when Muslims, Jews or Christians claim to be children of Abraham, they are all bound to be right.

"No matter the languages we speak or the color of our skin, we share ancestors who planted rice on the banks of the Yangtze, who first domesticated horses on the steppes of the Ukraine, who hunted giant sloths in the forests of North and South America, and who labored to build the Great Pyramid of Khufu," Olson and his colleagues wrote in the journal Nature.

How can they be so sure?

Seven years ago one of Olson's colleagues, a Yale University statistician named Joseph Chang, started thinking about how to estimate when the last common ancestor of everybody on Earth today lived. In a paper published by the journal "dvances in Applied Probability," Chang showed that there is a mathematical relationship between the size of a population and the number of generations back to a common ancestor. Plugging the planet's current population into his equation, he came up with just over 32 generations, or about 900 years.

Chang knew that answer was wrong because it relied on some common, but inaccurate, assumptions that population geneticists often use to simplify difficult mathematical problems.

For example, his analysis pretended that Earth's population has always been what it is today. It also assumed that individuals choose their mates randomly. And each generation had to reproduce all at once.

Chang's calculations essentially treated the world like one big meet market where any given guy was equally likely to pair up with any woman, whether she lived in the next village or halfway around the world. Chang was fully aware of the inaccuracy–people have to select their partners from the pool of individuals they have actually met, unless they are entering into an arranged marriage. But even then, they are much more likely to mate with partners who live nearby. And that means that geography can't be ignored if you are going to determine the relatedness of the world's population.

A few years later Chang was contacted by Olson, who had started thinking about the world's interrelatedness while writing his book. They started corresponding by e-mail, and soon included in their deliberations Douglas Rohde, a Massachusetts Institute of Technology neuroscientist and computer expert who now works for Google.

The researchers knew they would have to account for geography to get a better picture of how the family tree converges as it reaches deeper into the past. They decided to build a massive computer simulation that would essentially re-enact the history of humanity as people were born, moved from one place to another, reproduced and died.

Rohde created a program that put an initial population on a map of the world at some date in the past, ranging from 7,000 to 20,000 years ago. Then the program allowed those initial inhabitants to go about their business. He allowed them to expand in number according to accepted estimates of past population growth, but had to cap the expansion at 55 million people due to computing limitations. Although unrealistic in some respects–55 million is a lot less than the 6.5 billion people who actually live on Earth today–he found through trial and error that the limitation did not significantly change the outcome with regard to common ancestry.

The model also had to allow for migration based on what historians, anthropologists and archaeologists know about how frequently past populations moved both within and between continents. Rohde, Chang and Olson chose a range of migration rates, from a low level where almost nobody left their native home to a much higher one where up to 20 percent of the population reproduced in a town other than the one where they were born, and one person in 400 moved to a foreign country.

Allowing very little migration, Rohde's simulation produced a date of about 5,000 B.C. for humanity's most recent common ancestor. Assuming a higher, but still realistic, migration rate produced a shockingly recent date of around 1 A.D.

Some people even suspect that the most recent common ancestor could have lived later than that. "A number of people have written to me making the argument that the simulations were too conservative," Rohde said.

Migration is the key. When a people have offspring far from their birthplaces, they essentially introduce their entire family lines into their adopted populations, giving their immediate offspring and all who come after them a set of ancestors from far away.

People tend to think of pre-industrial societies as places where this sort of thing rarely happened, where virtually everyone lived and died within a few miles of the place where they were born. But history is full of examples that belie that notion.

Take Alexander the Great, who conquered every country between Greece and northern India, siring two sons along the way by Persian mothers. Consider Prince Abd Al-Rahman, son of a Syrian father and a Berber mother, who escaped Damascus after the overthrow of his family's dynasty and started a new one in Spain. The Vikings, the Mongols, and the Huns all traveled thousands of miles to burn, pillage and–most pertinent to genealogical considerations–rape more settled populations.

More peaceful people moved around as well. During the Middle Ages, the Gypsies traveled in stages from northern India to Europe. In the New World, the Navaho moved from western Canada to their current home in the American Southwest. People from East Asia fanned out into the South Pacific Islands, and Eskimos frequently traveled back and forth across the Bering Sea from Siberia to Alaska.

"These genealogical networks, as they start spreading out they really have the ability to get virtually everywhere," Olson said.

Though people like to think of culture, language and religion as barriers between groups, history is full of religious conversions, intermarriages, illegitimate births and adoptions across those lines. Some historical times and places were especially active melting pots–medieval Spain, ancient Rome and the Egypt of the pharaohs, for example.

"And the thing is, you only need one," said Mark Humphrys, an amateur anthropologist and professor of computer science at Dublin City University.

One ancestral link to another cultural group among your millions of forbears, and you share ancestors with everyone in that group. So everyone who reproduced with somebody who was born far from their own natal home–every sailor blown off course, every young man who set off to seek his fortune, every woman who left home with a trader from a foreign land–as long as they had children, they helped weave the tight web of brotherhood we all share.

Continued . . . Miranda teaches the frame drum at various locations throughout the Los Angeles area, such as North Hollywood, Long Beach, Topanga, and Pasadena. In the ancient cultures of the Mediterranean, the frame drum was used for religious functions, rites of passage, and communal bonding. In her workshops, she teaches the hand held position, playing with hands and fingers, the basic strokes and sounds of the drum, explores different rhythm and stroke combinations, and weaves in the symbology and intention behind the drum strokes.

We send our gratitude, love, support, and prayers to Miranda. This small acknowledgment is for the large and beautiful work you have created in our society. Truly, Miranda, the world is a better place because you are here.
 

The Roots of Hallow’s Eve

Continued . . . Everything has a shadow side, and Hallow's Eve and the Winter Solstice make up the shadow side of the year. Without shadow, light would be incomprehensible.

Cambodians call their dead to supper, "Oh, you who are our ancestors, who are departed, deign to come and eat!" Ritual food is placed on tables in Persia, West Africa, Sicily, Italy, and present-day Mexicans have a picnic in the cemetery, delicacies laid out for the living and the dead alike. Until recently, "ghost" and "guest" were pronounced the same, and both are derived from the Germanic root, "geist".

Hallow's Eve came to America when the potato famine in 1846 forced a million Irish immigrants to sail to our shores. It wasn't until the Eleventh Century that Christians claimed it for their own, emphasizing All Souls Day, and All Saints Day.

The symbols used in North America--ghost figures, masks, fires, and food--are the same as those used thousands of years ago in ancient Egypt for the Isia.

The Isia was a six day festival to commemorate the death of the corn God, Osiris, even though it was named after his consort, Isis. Participants masqueraded as Goddesses and Gods reenacting the saga of Osiris' death, disappearance, and rebirth. Although he dies in the fall, just as the corn is scythed, he is reborn as the springtime corn and is finally consumed as bread, living again in those humans who consume his sacred loaves. The Isia honored all departed souls. The Egyptians' Isia traveled to Greece and Rome, and was most likely the beginning seed of the Celtic Samhain.

One should perform rituals for strength and commitment in order to achieve goals set for the coming year. If the veil is thin between the living and the dead, then most assuredly, the veil is thin between all worlds. Think about how your life touches and interacts with various worlds, not just the physical and emotional worlds of our friends and associates, but the worlds of daydream, nightdream, meditation, trance, guided journeys, and individual spirit journeys where you might travel to the Upper or Lower World. Acknowledge the existence of All Worlds.

Hallow's Eve is a time to seek personal clarity, and also the time to think about how to heal Mother Earth for Herself and all her children.

Reflect on your loved ones who have passed on and now know the Mysteries of the Universe. Reflect on that which is negative that must be banished, but also look ahead knowing the springtime will come, and those seeds lying dormant in the cooling earth will surely sprout into green, healthy plants to sustain us through the summer.
