On 26 Jun 00 two research teams, the publicly-funded UK-US Human Genome Project and the
commercial Celera Genomics Corporation, jointly announced success in “decoding” (actually,
listing the sequence of) the 3.1 billion bits of DNA(the”building blocks”)of human beings. This
knowledge will enable our species from now on to change its own structure and abilities in
multiple ways. So, how we use and limit this new power will be one of the global issues of the
twenty-first century. That’s why these non-technical articles on the question are specially high-lighted. The broadest (not the earliest) is the Survey by Geoffrey Carr,”Life Story: The Human
Genome”(1-16);supported by”The Genetic Starting-Line” (Editorial:21-2)in The Economist 01 Jul
00:-genes, the“packages”of information [instructions] people inherit from their parents and use
to put together and run themselves, can be passed intact through generations. They are
composed of a chemical - DNA - which can”both encode [convert into extremely compact form]
vast quantities of information and replicate [make exact copies of] what it encodes”(3).
Laboratories are now“decoding”the DNA information for various species(30 complete; 100
nearly).“[U]nravelling... the full sequence of the human genome - a list, in order, of
the[3.1b]chemical bases that encode the information needed to assemble and run a human body
- is a scientific wonder. Knowing the sequence is really just the beginning. The...benefits will
come from...interpreting the data and coming up with uses for them”(21). The Survey claims this
accomplishment ”has brought the science of biology to a new threshold. And it may well have
brought medicine, agriculture, industry and even philosophy to a new threshold too”(3). After
a brief explanation of the biology involved, the Survey summarizes the probable impact
of“genomics”in each of those four broad areas. It concludes:”People now alive will witness the
synthesis of completely artificial life forms...and the creation of new species, not merely new
varieties, of living things. They will see the routine incorporation of biology into industrial
processes [and into essential food sources to feed a seriously undernourished and expanded
world population]. They will see a revolution in medicine for themselves, and the birth of people
whose biology has been optimised from conception to be resistant to disease and old age. They
may even see a world where children are tailored to the wishes of their parents”(16). Hence the
globality of the scientific and ethical issues. The Economist 16 May 98”Genetic Warfare: A
Private Genome Project” (111-2)-announces the beginning of the public-private competition with
the Celera project’s establishment, and offers pretty technical information on its new approach.
This is described as a new and rapid process for reading or"sequencing"the human genome,
the key in biotechnology for finding out what genetic messages pieces of DNA carry. Developed
by two private US companies, the technology refines existing ideas and may be able to provide
from scratch a complete sequence of the 3.1b genetic "letters"that constitute the human genome
as soon as 2000, and at a cost of $150-200m. This compares with the UK-US joint project,
expected to take another seven years (total 15), and costing $4 billion. Nicholas Wade,”After 10
Years’ Effort, Genome Mapping Team Achieves Sequence of a Human Chromosome”in New York
Times 02 Dec 99:-reports the UK-US Human Genome Project had achieved a milestone by
effectively decoding for the first time all key information in a human chromosome, a total of
33.5m units of DNA. Although this is the second-smallest chromosome of the 23 pairs in a
human cell, those involved feel it validates their approach:”A new era has dawned...as we now
have the essentially complete structure of the first human chromosome”. Understanding the
human genome is “expected to yield vast medical benefits, because almost every disease has
a genetic component...This is a phenomenal historical moment: to see a full chapter of the
human instruction book”. Consortium target year to decipher all human DNA was now given as
2005, so rivalry was clearly affecting events. The Economist 04 Dec”Genomic
Pronouncements”(77-8):-reports on the same development, gives new detail about the two
techniques, and urges the teams to work together. It admits, however, that commercially-valuable patents are an increasingly serious dilemma in this field. Steve Lohr,“IBM Plans
Computer to Work at Speed of Life” NYT 06 Dec:-reports IBM’s decision to undertake a five-year,
$100 million program to build a super-computer that will run at 500 times the speed of the
world’s fastest computer. The multi-disciplinary paragon (named Blue Gene) is designed to
simulate an extremely common biological routine: the process by which amino acids in a living
body intricately “fold”themselves into proteins in less than a second. Blue Gene will still take
a year to simulate folding one protein, using the new“origami”guide already produced by the
Human Genome Project. Full-fledged proteins are the body’s “molecular work force”, doing
chores ranging from metabolizing food to fighting disease. Blue Gene would“help supply
fundamental insights into the basic physics and chemistry of biology, opening the door to a new
understanding of diseases and more effective [gene-specific]drugs”. Wade,”Rivals on Offensive
as They Near End of Genome Race”NYT 07 May 00:-this is mainly a report on the imminent
climax of the competing and differing research programs being undertaken under increasing
pressure and at high cost by the academic consortium and the Maryland-based private company.
Although that news is inevitably short-lived, this substantial but non-technical article offers
much useful background material. It provides a survey of the reasons for both the research and
the rivalry, and an outline of their history. Above all, it describes as well the debate -found in
many“public-good” areas of research- over whether widely-useful knowledge should be made
freely and globally available, or whether/when patent rights should apply to encourage the often
enormous investment in possibly-futile research. Wade,”Rivals in the Race to Decode Human
DNA Agree to Cooperate”NYT 22 Jun:-after much heated negotiation, at the finish
line”cooperation outweighed the attractions of laying claim to one of science’s greatest prizes
independently...Though Celera’s version[was] further advanced, it relied on the consortium’s
data to an extent that may turn out to have been essential”. Wade,”Now, the Hard Part: Putting
the Genome to Work”NYT 27 Jun:-as noted, on 26 Jun the former rival organizations announced
they had completed the first rough map of the human genetic code, a scientific milestone
described as biologically equivalent to landing on the moon. While very complex, the event is
of great importance in so many fields of human interest -health, physical/mental ability,
creativity, emotion, longevity, relationships, reproduction, potential, and even purpose - that both
the US President and the British Prime Minister made statements about it, and the more
thoughtful media provided many analyses. This excellent article, like The Economist Survey,
describes the massive global implications for both science and ethics. It therefore contains
sections on: [Medical, Evolutionary Aspects]; Annotating the Genome; Proteins and Cells;
Tracking Human Variations; Ethical Implications. Associated Press,”Scientists Complete Rough
Draft of Human Genome” 26 Jun:-”Decoding the genome involves placing in correct order the
3.1b base pairs, or sub-units that make up human DNA. Imbedded in this DNA are about 50,000
genes”. Kenneth Chang,”Data From Genome Project Transforming Biology Research”NYT 26
Jun:-”This will allow you to concentrate your effort into what is going to have the greatest impact
on biomedical research” (Charles Zuker, UCSD). AP”Genome Map May Spur Biotech Interest”
27 Jun:- “The bullish outlook for the biotech industry reflects the expectation that scientists will
be able to use the human genome research to develop more effective drugs to treat some of the
world’s most devastating diseases, such as cancer and Alzheimer’s”. Andrew Pollack,”US
Hopes to Stem Rush Toward Patenting of Genes”NYT 28 Jun:-”With the technology in so much
flux, gene patenting is likely to be the subject of numerous court battles and might be revisited
by Congress. For companies that have staked their futures on owning the rights to genes, and
for science in general, a lot is riding on the outcome”. AP ”Genes May Cause 25% of 3 Major
Cancers”13 Jul:-Nordic research concludes genes account for 42% of the risk for prostate
cancer, 35% for colorectal cancer and 27% for breast cancer, much more than was thought.”The
rest of the cases are caused by...smoking and diet, or what happens to [people]”. AP”Kenyan
Mice Help Decode Genome”16 Jul:-”Mice and humans... have virtually identical sets of genes,
but the sequences differ slightly....With about 97% of the human genome sequenced, the
equipment and resources involved...are now being dedicated to the mouse”. Carol Kaesuk Yoon,
”Agriculture Takes Its Turn in the Genome Spotlight”NYT 18 Jul:-”In a scientific first,...a team
of more than 200 researchers [in Brazil] has for the first time deciphered the complete DNA
sequence of an organism that causes a plant disease. [The bacterium, xylella fastidiosa,]
contains surprises, including[genes thought]to be peculiar to animal pathogens [disease-producers]and a complete lack of some[thought]essential to plant disease organisms”. The
Economist 22 Jul:”Brazilian Science: Fruits of Cooperation” (79):-this more detailed account of
the xylella fastidiosa triumph(which directly relates to serious damage to orange groves -and
California vineyards: see p.71 of 12 Aug issue)praises Brazil’s very considerable ability and
success in the field of genetics, and emphasizes “there is no reason why countries such as
Brazil cannot compete in leading-edge science”. It reports that just after publishing this first-ever
genome sequence of a plant pathogen, Sao Paulo scientists announced another success:”the
composition of 279,000 human expressed-sequence tags [ESTs], small pieces of DNA that allow
genes to be located along chromosomes” (information directly relevant to cancer of the head
and neck-unusually common in Brazil). Both events are of“global significance”and have
attracted international funding for other genetic projects. Pollack,”Company Seeking Donors of
DNA for a `Gene Trust’“NYT 01 Aug:- a new Web site DNA.com has been set up by a California
firm”DNA Sciences” to”recruit people to donate their DNA to help find genes that cause
disease”. It hopes to get 50,000-100,000 donors to contribute to its “gene trust” through altruism,
since:“The knowledge we gain...has the potential to change medicine forever”.
The”trust”reflects the fact that-with the human genome now decoded-“studies to link genes to
disease are starting to be done on an unparalleled scale, involving far more people than ever
before”. Scientists must catalog hundreds of thousands of differences in the genetic makeup
of individuals in order to determine which contribute to which disease or to the effectiveness of
a particular drug, and many genes may contribute to common ones like cancer, heart disease
and diabetes. The thousands of patients/volunteers needed to do this will have their data
“anonymized”. Problems include inaccurate medical histories, too heterogeneous samples, and
cost. The Economist 05 Aug:"The Cholera Genome” (78):- the AIDS pandemic of the 19th
Century was cholera:“fearful, fatal and incurable”. Even given the accelerating rate at which full
DNA sequences are being published, now having that of El Tor,”one of the ugliest types of Vibrio
cholerae”, is particularly welcome. Unless treated quickly, the bacteria kill up to half the victims
in days by destroying their intestinal lining. Being able to exploit the El Tor sequence could aid
vaccine-makers: many of the”genes may encode completely novel proteins”. AP”Baltic State to
Establish One of the World’s First National Gene Banks” onhealth.com 9 Aug:-reports Estonia
has given initial approval to plans to set up a gene bank where detailed genetic codes of over
1m people would be stored. Even with a total population of only 1.4m, the depository will take
5 years and $200m to complete. The only other nation with such a project is Iceland, with a
population of 270,000. Estonian participation is voluntary, but 90% have volunteered; the
Icelanders are automatically included if they don’t specifically refuse. Access to the bank would
be limited to researchers, but Estonia hopes the program will”spur the growth of a dynamic
biotechnology sector”. Eric S. Lander,”After Deciphering the Map, the Next Task Is a Guidebook
for the Human Genome”NYT 12 Sep:-a very useful article by a scientist personally involved in
the human genome project. His own team’s next project is to try to “glean meaning from the
breathtaking variations in the chromosomal landscape...In effect, we’re preparing the first edition
of a guidebook, describing the landmarks of the human chromosomes, designed to shape the
experience of generations of genome travelers to come”. Lander stresses that his work is just
one of many ways to“breathe meaning”into the human genome; probing the social meaning of
genetics alone involves such themes as genetic identity, species boundaries, biotechnology,
evolution and racism -and the ethics. The Economist 21 Oct:”Testing Time: Genetic Testing and
Insurance”(93-4):-a major ethical, financial/business, and health issue is resulting from the
expanding capacity to determine whether a human carries genes that threaten an early and
debilitating death. Any insurance company with this information could either refuse coverage
or demand much higher premiums from those found carrying such genes. This would also
weight companies’ normal“statistical gamble”heavily in their favour. However, most
governments now restrict or prohibit the use of genetic-test information by insurers. This tilts
the odds in the opposite direction and enable those with dangerous genes to take out huge
policies and sell them to third parties. At the very least, those with fore-knowledge of their health
prospects could adjust the size and type of their policies accordingly -and threaten the future
of the insurance business. Hence compulsory disclosure seems likely. Result: the”safe”buy no
insurance; the“threatened”cannot get/afford it.“[G]enetic testing may become the most potent
argument for state-financed health care”. Matt Ridley Nature Via Nurture: Genes, Experience, and
What Makes Us Human(Toronto:HarperCollins 2003):- the already vast - and growing - powers
and frustrations now felt by the 6.5 billion people on earth makes intensive global cooperation
essential to human survival from unprecedented violence, avoidable deaths and planetary
threats. Unfortunately, many of the traditional ways homo sapiens has thought and acted must
be persuaded to change, so greater knowledge of how and why some relate to others will be
essential. This book reports on the basic sources. The Economist 10 Apr 03 "Evolutionary
Biology: The Generation Game"(Review):-"New book travels to frontiers of science in attempt
to resolve ongoing quarrel over genetics and environment. Are human personalities in all their
variety...essentially the result of nature, of the genes we inherit from our parents? Or are we
made by the worlds - social economic and familial - into which we are born? According to
Ridley,.. nature and nurture collaborate; they are partners, not competitors. Every human
characteristic depends both on the genetic package we inherit and on the world into which we
are born, no gene by itself makes anything. No environment makes a human mind without the
collaboration of human genes packaged into a human egg". Ridley writes in his Prologue: "I
believe human behavior has to be explained by both nature and nurture. I am not backing one
side or the other. But that does not mean I am taking a 'middle of the road' compromise... I intend
to make the case that the genome has indeed changed everything, not by closing the argument
or winning the battle for one side or the other, but by enriching the argument from both ends till
they meet in the middle. Discovery of how genes actually influence human behavior, and how
human behavior influences genes, is about to recast the debate entirely. No longer is it nature
versus nurture but nature via nurture. Genes are designed to take their cues from nurture...
Stories from the deepest recesses of the genome show how the human brain is built for nurture.
My argument [is]: the more we lift the lid on the genome, the more vulnerable to experience
genes appear to be"; Economist 23 Dec 06"Liberalism And Neurology: Free To Choose?"(16-8):-official summary:"Modern neuroscience is eroding the idea of free will". Highlights:"Free will
is one of the trickiest concepts in philosophy, but also one of the most important. Without it, the
idea of responsibility for one's actions flies out the window, along with much of the glue that
holds [societies] together[, and] social relations would be very different. For millennia, question
of free will was province of philosophers and theologians, but it actually turns on how the brain
works. [Now] possible to watch the living human brain in action in a way that begins to show in
detail what happens while it is happening. [Issue offers major and globally important "Survey
of the Brain"(1-12). Its six essays' titles/own summaries are: "Who Do You Think You Are?":-"Modern neuroscience, says Geoffrey Carr, is groping towards answer to the oldest question
of all: who am I?"; "Captain Kirk's Revenge":-"Emotion is essential to human survival";
"Brainbox":-"A history and geography of the brain"; "Dreamweavers":-"Perfect memory is of
everything and nothing"; "As Others See Us":-"Dealing with people changes our minds"; "I
Think, Therefore I Am, I Think":-"Consciousness awaits its Einstein".] This ability doing more
than merely adding to science's knowledge of brain's mechanism. Also emphasising to public
that brain really is a just mechanism, rather than a magician's box that is somehow outside the
normal laws of cause and effect. Science is not yet threatening free will's existence [but] will
shrink the space in which free will can operate by slowly exposing the mechanism of decision
making. [Already seeking] to lock up people with personality disorders thought [likely] to make
them commit crimes, before any crime is committed. Such disorders are serious pathologies...
Nor is it only the criminal law where free will matters... Liberals say individuals should be free
to [drugs] or not. Erode free will, and you erode that argument. In fact, you begin to erode all
freedom. Without belief in free will, ideology of freedom is bizarre. Though it will not happen
quickly, shrinking the space in which free will can operate could have some uncomfortable
repercussions". On same subject is major essay by Dennis Overbye"Free Will: Now You Have
It, Now You Don't"NYT 02 Jan 07:-"A bevy of experiments in recent years suggests conscious
mind is like a monkey riding a tiger of subconscious decisions and actions in progress,
frantically making up stories about being in control. As result, physicists/neuroscientists/
computer scientists have joined heirs of Plato and Aristotle in arguing about what free will is,
whether we have it, and if not, why we ever thought we did in first place"; Economist 16 Jun
07"The RNA Revolution: Biology's Big Bang"(Edit.13):-official sum:"What physics was to the
20th century, biology will be to the 21st - and RNA will be a vital part of it". Highlights:-"For more
than 50 years, fundamental story of living things has been tale of interplay between genes, in the
form of DNA, and proteins, which the genes encode and which [keep] living organisms living.
Past couple of years have seen rise of third type of molecule: RNA. [I]ts role had [earlier] seemed
restricted to fetching/carrying for DNA/proteins. Now RNA looks every bit as important[:] it may
be main regulator of what goes on in a cell i.e.operating system, as well as author of many other
activities". See"Briefing: RNA: Really New Advances"(87-9):-"Molecular biology undergoing its
biggest shake-up in 50 years, as hitherto little-regarded chemical called RNA acquires an
unsuspected significance"; and "RNA-Based Drugs: Little Hopes"(88):-official sum:"New classes
of drugs that exploit new RNAs are in development". Edit.cont'd: "Molecular biologists... barely
a clue [yet of] what is going on [-] a sense of barely contained expectations [-] a feeling of
advancing into... exciting/mysterious... unknown. [T]here is a good chance that... distinguishing
feature of 21st century will be biological technology... Simple genetic engineering is now routine;
indeed, the first patent application for an artificial living organism has recently been filed".
See"Artificial Life: Patent Pending"(92-4):-"Craig Venter... 16 years ago attempted to patent parts
of several hundred genes. [Now] he is proposing to patent not merely a few genes, but life itself[,
eventually via] the synthetic bacterium[he's] been working on". Edit.cont'd:"The other driving
force of technological change - necessity - is also there. Many big problems facing humanity are
biological, or susceptible to biological intervention[:] how to deal with ageing population[;]
climate change, intimately bound up with biology[;] risk of a new, lethal infection suddenly
[biological] pandemic as result of modern transport". See"The World Health Organization:
Preventing Pandemics"(67-8):-official sum:"The new powers vested in [WHO Director-General,
Dr Margaret Chan] should, in theory, cut the risk of killer diseases raging round the world".
Edit.cont'd:"Biology more than describes humanity's place in universe. It describes humanity
itself, and... RNA may be an important part of that... Traditional genes not as important as
proponents of human nature had suspected, nor as proponents of nurture feared. Instead,
solution seems to lie in RNA operating system of the cells. This gets bigger with each advance
in complexity, and noticeably different in a human from that in brain of a chimpanzee. If RNA is
controlling the complexity of the whole organism, suggests operating system of each cell is not
only running cell in question, but linking up with those of other cells when creature developing.
Organs such as the brain are the result of a biological internet, [and] the search for the essence
of humanity has been looking in the wrong genetic direction. [E]ventually, the truth will out";
David Sloan Wilson Evolution For Everyone: How Darwin's Theory Can Change the Way We
Think About Our Lives(New York: Delacorte Press 07):-initial paragraph, that offers the author's
own summary of the 400 pages:"This is a book of tall claims about evolution: that it can become
uncontroversial; that the basic principles are easy to learn; that everyone should want to learn
them, once their implications are understood; that evolution and religion, those old enemies who
currently occupy opposite corners of human thought, can be brought harmoniously together".
The dustcover includes: "With stories that entertain as much as they inform, Wilson outlines the
basic principles of evolution and shows how, properly understood, they can illuminate the length
and breadth of creation, from the origin of life to the nature of religion. Now everyone can move
beyond the sterile debates about creationism and intelligent design to share Darwin's panoramic
view of animal and human life, seamlessly connected to each other. [B]asic evolutionary
principles are... foundation for humanity's capacity for symbolic thought, culture, and morality".
While Wilson is not specifically critical of religions, he is clearly concerned that: "According to
the most recent Harris Poll, 54% of US adults believe that humans did not develop from earlier
species"(2).Natalie Angier(New York Times review 08 Apr 07)writes:"a sprightly, absorbing and
charmingly earnest book that manages a minor miracle, the near-complete emulsifying of
science and the 'real world', ingredients too often kept stubbornly, senselessly apart"; Bill
Bryson A Short History of Nearly Everything(New York: Broadway Books 03):-pre-bestseller
author of many/widely-varied books, undertook "informative journey into world of science,.. his
greatest challenge yet: to understand - and, if possible, answer - oldest, biggest questions...
about the universe and ourselves... Result is a sometimes profound, sometimes funny, and
always supremely clear/entertaining adventure in the realms of human knowledge"(publisher).
Even new "lavishly illustrated" Nov 05 hardcover edition of 624pp available from Barnes & Noble
to all @US$28.00. Favourable Ed Regis NYT review(18 May 03)states:"Bryson achieved exactly
what he'd set out to do, and, moreover, [did] it in stylish, efficient, colloquial and stunningly
accurate prose... The basic facts of physics, chemistry, biology, botany, climatology, geology -
all these and many more are presented with exceptional clarity and skill". My own reaction is that
this easily available/readable reference on all not-personally-specialised scientific subjects
should ideally be read - or at least be used for topic-reference - by all in this very unstable world;
Economist 29 Sep 07"Civil Liberties: Surveillance and Privacy: Learning to Live With Big
Brother"(62-4):-official sum:"[L]ooks at the new technologies for collecting personal information,
and the dangers of abuse". Highlights:"[S]marter technology... that has been designed to fight
