Matt Ridley from The Genome
In the
beginning was the word. The
word proselytized the sea with its message, copying itself
unceasingly and forever. The
word discovered how to rearrange chemicals so as to capture little
eddies in the stream of entropy and make them live.
The word transformed the land surface of the planet from a
dusty hell to a verdant paradise.
The word eventually blossomed and became sufficiently
ingenious to build a porridgy contraption called the human brain
that could discover and be aware of the word itself.
'As
the earth and ocean were probably peopled with vegetable
productions long before the existence of animals; and many
families of these animals long before other families of them,
shall we conjecture that one and the same kind of living filaments
is and has been the cause of organic life.’
Asked the polymathic poet and physician Erasmus Darwin in
1794. It was a
startling guess for the time, not only in its bold conjecture that
all organic life shared the same origin, but sixty-five years
before his grandson Charles’s book on the topic, but for its
weird use of the word ‘filaments’.
The secret of life is indeed a thread.
The filament of DNA is information, a message
written in a code of chemicals, one chemical for each letter. It is almost too good to be true, but the code turns out to
be written in a way that we can understand. Just like written English, the genetic code is a linear
language, written in a straight line.
Just like written English, it is digital, in that every
letter bears the same importance.
Moreover, the language of DNA is considerably simpler than
English, since it has an alphabet of only four letters,
conventionally known as A,C,G and T.
In the beginning was the word. The word was not DNA. That
came afterwards, when life was already established, and when it
had divided the labor between two separate activities: chemical work and information storage, metabolism and
replication. But DNA
contains a record of the world, faithfully transmitted through all
subsequent eons to the astonishing present.
From Frankenstein By Mary Shelley
But these philosophers who hands seem only to
dabble in dirt, and their eyes to pore over the microscope or
crucible have indeed, performed miracles.
They penetrate into the recesses of nature and show how she
works in her hiding places.
Life and death appear to me ideal bounds,
which I should first break through, and pour a torrent of light
into our dark world.
Sermon
“So
much has been done,” exclaimed the soul of Frankenstein – “but
more, far more, I will achieve.
I will pioneer a new way, explore unknown powers, and
unfold to the world the deepest mysteries of creation.”
With these lofty words, the scientist of Mary Shelley’s
often-misinterpreted book begins his fearsome adventure into the
creation of life. Assembling parts of dead bodies the doctor builds a single
human form and harnessing a raw pulse of electricity, brings it to
life. He dreams of
defeating mortality and of comprehending the fundamental language
of life. As he labors alone – fevered – haunting graveyards and
avoiding the companionship of the living, a monster is indeed
created – it is the doctor himself.
And the unsightly creature he vivifies is no monster but a
newborn giant – hungry, lonely, yearning, ignorant, rejected and
abandoned by his creator.
Mary Shelley set out not to write a Gothic thriller but to
ask, as science and revolution ran wild in her world:
How woman and man could best serve the cause
of freedom – which struggled everywhere around her
How we could, as Annie Dillard says, aid and
abet creation – which was so challenged
And how we could be wise and just expatriates
of the garden of blissful ignorance – loving and respectful
citizens of the world.
These questions have not gone away – and never will.
The world today is filled with bloody terrors that clothe
themselves in the rhetoric of revolution and religion.
And science is reaching up into the other tree – the tree
of life and drawing down that other fruit on whose account we were
banished – “lest man become like one of the gods.”
The serpent was an honest messenger -- therefore we must be
wise as serpents. And
here it is -- St. Patrick’s Day – when the snakes were driven
out of Ireland – it is a day I like to celebrate because I
respect the Irish ability to find any good reason for a party –
but I also celebrate the snakes – for they spread the truth –
they speak the truth.
The moral questions at the heart of life never go away.
One apple is not sufficient to sustain generations.
We are the heirs of the garden of wisdom and healing.
We live on the mind’s sharp edge between good and evil,
the body’s longing for this world, and the heart’s passion for
life. Our religion
arose because those who came before us believed that we were
divine and wanted us to take seriously our glory, our wisdom, and
our frailty. When
Reverend William Ellery Channing -- in the same years as Mary
Shelley was writing -- spoke of our celestial inheritance – he
meant both our power – almost godlike – and our deep moral
responsibility.
Today his words of a celestial inheritance sounds even more
far-seeing as we can see in our own atoms the stuff that stars are
made on – the spectrum of the cosmos.
And now we can see in the intimate cells of our bodies the
very history of this world – our connection with every person on
it – and the story of our sufferings and our joys.
Frankenstein said that he would unfold the mysteries of
creation. But he unfolded instead his own shortsightedness and narrowed
heart. I can unfold
one of the mysteries of creation.
You can’t see the details from here but this is the human
genome – the archetype of life – the thread of which we are
woven. It is a
wonder! When I read
about the debates over whether views of creation other than
evolution should be taught I want to shout – is your god so tiny
as to care? Will you also teach of the Popul Vuh, of Enkidu, of
Brahma and wheel of life and death, of Pan Gu and Hun Dun, of the
Great Spirit, of Izanagi and Izanami, of the Dreamtime?
If you speak of god let that god be larger than one single
religious story of creation – let those stories stand aside as
the great metastories they were.
And let the god you evoke be minute as the genome and more
complex – let that god be great as the cosmos and as full.
Richard Dawkins
wrote: “ Evolution is an enchanted loom of shuttling DNA codes,
whose evanescent patterns, as they dance their partners through
geological deep time, weave a massive database of ancestral
wisdom, a digitally coded description of ancestral worlds and what
it took to survive in them.”
Our weaving of DNA tells of journeys from one hemisphere to
another, through icy cold and of scourging sun, in disease
infested woods, in times of meeting and parting, of plenty and of
starvation – of adaptation and settlement.
A sacred true scripture of earth time.
I am sure that this lyrical beauty was not what Gregor
Mendel envisioned as he studied peas and other plants.
I am sure that he was searching for order – for the
patterns and sense of life – as a religious man this desire for
order must have moved him. Much
later Francis Crick and John Watson were more certain of the
cosmic beauty of the double helix of DNA they had discovered –
Watson, late in the process of discovery and testing said, “Happily,
we had lunch, telling each other that a structure this pretty just
had to exist.”
Since that time the exploration of DNA has
been pretty steady. But
not always pretty – it is a fullness of life that is encoded
into our genes. There are diseases that are genetic or chromosomal in origin
– suffering embedded in the strands of our being. They touch every one of us.
In the color of our eyes, the loved ones we have lost, the
conditions we inherit, the mysterious mutations we suffer. Hidden
deep in the threads of our lives – in the person next to you --
are mysteries, realities unfolded and waiting to unfold –
realities of wonder and sorrow. Every one of us here is this complex weaving – and has
encountered the frayed edge of this tapestry of life. Of this, as I speak with you today, I am keenly mindful.
In some ways, we have learned just enough to suffer with
more awareness. But
there are hopeful signs.
We have mapped the human genome, well, in concert thousands
of people mapped the genome.
I won’t assume that you know anymore than I did when I
began this topic early in the year.
Perhaps you will understand better if I tell you that I’m
still a little edgy about my microwave oven and that my first
semester in Physics made me despair – well the professor was
terrible. Yet, I
found that I could teach myself complex math so that it became a
late night meditation for me.
But this learning curve about the power of the genome is
almost staggering. When
I first began to read Ridley’s book on the Genome I had that
learning block – where the words have to be read over and over
and then, suddenly it opened up – clear and exciting – my
world – my body – our future. Of late this news of life it has been dwarfed by the acts of
cruelty that have rocked and continue to rock our world.
Don’t be fooled by the sleight of hand – there is power
afoot – and whether it bodes good or evil is in our hands – at
this time. Life and
the dream of healing is as much late breaking news as is death and
war.
I promise not to overwhelm you with scientific detail –
but this is our moment to comprehend and help to determine the
course of a genome-mapped future.
What does that mean? It
means that we are rapidly mapping the fundamental structure of our
genome – a gene is a portion of the overall genome – the
genome is like a general, generic, family portrait – a portrait
of the human family. It
is writ into every cell in our bodies and contains multitudes –
thousands of genes that determine thousands of human conditions.
Or really it is like a map – a huge map – if you could
spread it out there would be the whole country – the world and
all the roads and towns, the schools, and hospitals, the parks –
you get the idea – if you could just spread it out – but then
it would be huge – like the size of Rhode Island.
And there you are alone in the driver’s seat and the map
is all folded up in tiny folds – and you need the route around
Morristown, New Jersey. The
traffic is thick and the trucks roar over you.
The good news is that finally someone knows the bigger
picture – but there is no way to use it very easily yet.
And just like a map of the world that is all neat with vast
blue oceans and a nice rectangular shape and the US upright with
Texas at the bottom – we are deluded if we think that … the
world is flat and easy to cover because the map is. So it is with
the genome. It is
curled tightly within us – complex and twisted – carrying all
we need to know – sort of…The genome is made of strings of
genes – each one determining different traits – like the ones
for gender, or brown eyes, or cycstic fibrosis or for Sickle cell
– well it’s not really fair to say that there is a gene for
Sickle Cell. When the
gene stops working – that is when the danger begins.
And there are differing degrees of danger – some cases
are severe and some milder, some treatments help at least for a
while some – are ineffective. The interesting thing about this
gene is that if you could remove it – if you really could speed
down the highway, unfolding the map and find the very tiny town
and the hospital in that tiny town, the jiggling of the car would
prevent you from keeping your focus and really pinpointing it –
and then if you went there – what would you do?
Leaving aside the many unkind things that have been said
about New Jersey – the State where I was born – in Morristown,
in fact, -- if you change something about the route who knows what
sort of bottle neck you might cause down the road?
Will there be a bridge out suddenly?
The interesting thing about the non-functioning gene that
leads to sickle cell is that it also guards the bearer against
malaria – as long as it is only inherited from one parent – if
it is inherited from both you may be free of malaria but the other
thing may kill you. The
genome is an integrated circuit – and while we can begin to see
it we don’t fully grasp the relationship of one part of the
circuit to the others – we just know that the relationship is
vital. My brother in
law who works as a genetics counselor, uses another analogy –
that DNA is like a full bowl of long and tightly coiled pasta –
slippery with olive oil. And
there’s pepper sprinkled on it and one particular piece of
pepper that you want to find in this giant, slithery, bowl of long
and tangled noodles. If
you start early enough in the process of the formation of life –
like when there are only four or eight cells and strands or maybe
– risotto? Anyway, you might stand a chance – but even there
the pasta is a mess. If you could take the noodles out and stretch them you could
find it – it would still be dizzyingly hard – and it would, of
course, kill the cell… and, of course, the pepper is really all
over the pasta – like every cell in our bodies carries the map
of DNA. So, even if
we could find it in one strand in one cell there would be billions
more.
It is both glorious and humbling – first we can isolate
enough DNA to read a portrait of a person in it – to discover if
they have Huntingdon’s Chorea or Cystic Fibrosis – but we
cannot isolate that gene and fix it -- it is untreatable – and
even if we could fix one – there would be a billion more waiting
for us. And we might
hurry to eradicate or treat something that is only a
predisposition. Further,
since these strands of DNA are interlinked we don’t really know
the impact of interrupting the flow of information down the strand
– I mean suppose your architectural vision is somehow connected
to some other gene which has a relationship that runs through the
non-functioning gene and you would lose .. who knows.
Learning so much – that we are part of vast and ancient
family tree – but as Kaye McSpadden reminded me – we are
closely related to the fruit on it as well – we share fifty
percent of our genome with the genome of the banana – darned if
that’s not the cycle of life – we are almost as closely
related to our food as to one another.
Perhaps that is, in part, what makes life on Earth so
challenging. We eat
on a food chain of our own relatives.
And then – from a great distance in space perhaps we
earthling – trees and animals alike -- do look rather like
bananas down here – red, green, yellow, spotted – I like that
– it could be that I was early impressed by the lyrics of Frank
Zappa – and the mothers of invention – “call any vegetable,
call it by name – call them today – call any vegetable and the
chances are good – that the vegetable will respond to you.”
But, most likely I think I am at home in my intimate
connection with the banana because it makes me feel more at home,
as one, growing from, rooted in the tree of life, embodied and
embedded in this Earth.
I have faith that, like the bananas, we are on an
evolutionary path – in response to history and climate and –
all of it intertwined – we are evolving.
However, I also have faith that, unlike the banana our path
will lead us to shaping our own cellular destinies.
Of course, we have long begun – with livestock – using
test tubes to fertilize the eggs of the finest females with the
finest males. Or by
doing amniocentesis to ascertain certain genetic or chromosomal
disorders. We have
begun through the genetic testing of fertilized but unimplanted
eggs to discover the presence of disease factors – like
Huntingdon’s disease before the egg becomes a pregnancy.
And stopping the spread of a disease to a future
generation.
But now the ethical dilemmas begin to appear everywhere. There are countries where female fetuses are aborted.
At a gay pride march a group wears a t-shirt that says “Thanks
for the genes Mom!” I
worry about the mom’s who’d rather not be thanked – who
would test and change – if possible some queer gene if there is
one – and we would lose Rosie O’Donnell, Cole Porter, Oscar
Wilde, Leonard Bernstein, Adrienne Rich, Michelangelo, Jane Adams,
Alec Guinness, the sound track to half the Disney films –
especially Beauty and the Beast, some of this congregation, and a
goodly portion of my family.
A food scientist
friend of ours Barry – decrying the tight control of crop types
said, “God abhors a monoculture.”
Alike as we are, we are nourished on our differences as
well.
And then – we are made finer by our help to one another
– is that how we survive to the next evolutionary place?
This map, this scientific endeavor might leave you feeling
all powerful – or perhaps unsettled – after all if our past
and future are in our genes – where is our free will – simply
in how we manipulate our genome?
Nope – it turns out that chance and all the usual
intricate interconnections still hold true.
We are indeed part of an interdependent web and will never
be large enough to rule its destiny or to absolutely shape our
own. There has never
been and will not be an absolute God – not even ourselves.
But, I know that we will shape destiny. We will grasp the
tools and re-form life and destiny.
It will take time has taken time – but the moment of
budding is now – this is the time to determine the direction of
this science – and we, as moral persons – as persons of reason
and faith, of science and art, of justice and compassion – we
are wanted and needed in this time.
I want to watch cell divide and humans unite in the service
of life and goodness.
I am convinced –
after much reading and study that the yearning to alleviate
suffering runs strong in the Human Genome Project.
I feel relieved when Ridley says – “Human beings are an
ecological success” – I feel proud – but then he says –
“ the human species is by no means the pinnacle of evolution.
Evolution has no pinnacle.
Natural selection is simply the means by which life-forms
change to suit the myriad opportunities afforded by the
environment and other life forms.”
This is humbling yet profoundly theological statement: the
world was not made and cannot be shaped for us alone.
I am relieved to know that the world’s largest bioethics
program is run through the HGP – ELSI — studying ethical
social and legal issues. But
that does not check it off our list of concerns. We will take time
to continue to unfold the map and then to shape our world – but
we will do it – there is so much suffering to be alleviated –
so many children who come in broken. Therefore, I want us to shape
our world carefully – cautiously – humbly – waiting to learn
more about the interconnections – acting in compassion and not
in greed. Who should
own the patterns of life, who should control the resetting of life’s
thread? Who should
profit and by how much? How
do we free scientists to pursue the study they love and the share
the insights they discover? Who
defines the moment and nature of life?
When does a life form have inherent worth and when does it
not? Who judges when
only a god could judge well and our gods have a poor track record.
In truth, for all the hopes and ideals of the Matt Ridley’s,
the Francis Collins’, and my brother in law there will be those
who will exploit and misuse this newfound truth and will unfold
evil – some by mistake, some in greed, some in intentional
hatred and bitterness toward life. There will be mad scientists and lost creations.
This power that we are exploring and beginning to is,
indeed, god-like and fraught with risk.
It is for that reason that I ask us each to pick up a book
– that’s the easy step – or talk to a scientist – that’s
a little more daunting – to educate ourselves to be equal to
this shift that is unfolding around us.
Let us be wise as serpents exploring and speaking the truth
and be gentle as doves. Then
let us use our voices and our power – our education and
knowledge to ask the tough questions and help to shape the future
of this science – not as scientists but as global citizens.
From the words of Francis Collins, of the Human Genome
Project, I am heartened. In
an interview about the process of seeing a new gene identified he
said, “these moments of discovery become moments of worship.”
Yes – for the roots of the word worship have to do with
shaping that which is of worth – and it must be indeed an act of
worship to work with the thread of life itself – the thread of
worth and to envision the mending and making whole of that thread
and its web. As
Unitarian Universalists we claim a bridge between science and
religion that the book of life is being writ anew everyday and we
claim that sacred scripture is written not only in books but in
our hearts – and now we find it, as we might have guessed, in
our precious bodies and our connections with all of life.
May we be worthy indeed by shaping ourselves into those who
grow in wisdom and compassion, by leading our world in ethical
directions – may our every discovery be an act of worship – a
miracle of simple worthiness -- goodness -- an act of shaping a
common life that may heal and sustain us and our world.
Let us worship in Silence and reflection.
