Passage 1:蝴蝶农场
A
THERE’S no animal that symbolises rainforest diversity quite as
spectacularly as the tropical butterfly. Anyone lucky enough to see these
creatures flitting between patches of sunlight cannot fail to be impressed by
the variety of theirpatterns. But why do they display such colourful exuberance?
Until recently, this was almost as pertinent a question as it had been when the
19th-century naturalists, armed only with butterfly nets and insatiable
curiosity, battled through the rainforests. These early explorers soon realised
that although some of the butterflies’ bright colours are there to attract a
mate, others are warning signals. They send out a message to any predators:
“Keep off, we're poisonous.” And because wearing certain patterns affords
protection, other species copy them. Biologists use the term “mimicry rings” for
these clusters of impostors and their evolutionary idol.
B
But here's the conundrum. “Classical mimicry theory says that only a single
ring should be found in any one area,” explains George Beccaloni of the Natural
History Museum, London. The idea is that in each locality there should be just
the one pattern that best protects its wearers. Predators would quickly learn to
avoid it and eventually all mimetic species in a region should converge upon it.
“The fact that this is patently not the case has been one of the major problems
in mimicry research,” says Beccaloni. In pursuit of a solution to the mystery of
mimetic exuberance, Beccaloni set off for one of the megacentres for butterfly
diversity, the point where the western edge of the Amazon basin
meets the foothills of the Andes in Ecuador. “It’s exceptionally rich,
but
comparatively well collected, so I pretty much knew what was there,
says
Beccaloni.” The trick was to work out how all the butterflies were
organised and how this related to mimicry.”
C
Working at the Jatun Sacha Biological Research Station on the banks of
the Rio Napo, Beccaloni focused his attention on a group of butterflies
called ithomiines. These distant relatives of Britain’s Camberwell
Beauty
are abundant throughout Central and South America and the Caribbean.
They are famous for their bright colours, toxic bodies and complex mimetic
relationships. “They can comprise up to 85 per cent of the individuals in a
mimicry ring and their patterns are mimicked not just by butterflies, but by
other insects as diverse as damselflies and true bugs,” says Philip DeVries of
the Milwaukee Public Museum’s Center for Biodiversity Studies.
D
Even though all ithomiines are poisonous, it is in their interests to
evolve
to look like one another because predators that learn to avoid one
species
will also avoid others that resemble it. This is known as Miillerian
mimicry. Mimicry rings may also contain insects that are not toxic, but gain
protection by looking likes a model species that is: an adaptation called
Batesian mimicry. So strong is an experienced predator’s avoidance response that
even quite inept resemblance gives some protection. “Often there will be a whole
series of species that mimic, with varying degrees of verisimilitude, a focal or
model species,” says John Turner from the University of Leeds. “The results of
these deceptions are some of the most exquisite examples of evolution known to
science.” In addition to colour, many mimics copy behaviours and even the flight
pattern of their model species.
E
But why are there so many different mimicry rings? One idea is that species
flying at the same height in the forest canopy evolve to look like one another.
“It had been suggested since the 1970s that mimicry complexes were stratified by
flight height,” says DeVries. The idea is that wing colour patterns are
camouflaged against the different patterns of light and shadow at each level in
the canopy, providing a first line of defence against predators.” But the light
patterns and wing patterns don’t match very well,” he says. And observations
show that the insects do not shift in height as the day progresses and the light
patterns change. Worse still, according to DeVries, this theory doesn’t explain
why the model species is flying at that particular height in the first
place.
F
“When I first went out to Ecuador, I didn’t believe the flight height
hypothesis and set out to test it,” says Beccaloni.”A few weeks with the
collecting net convinced me otherwise. They really flew that way.” What he
didn’t accept, however, was the explanation about light patterns. “I thought, if
this idea really is true, and I can work out why, it could help explain why
there are so many different warning patterns in any one place. Then we might
finally understand how they could evolve in such a complex way.” The job was
complicated by the sheer diversity of species involved at Jatun Sacha. Not only
were there 56 ithomiine butterfly species divided among eight mimicry rings,
there were also 69 other insect species, including 34 day-flying moths and a
damselfly, all in a
200-hectare study area. Like many entomologists before him, Beccaloni used
a large bag-like net to capture his prey. This allowed him to sample the 2.5
metres immediately above the forest floor. Unlike many previous workers, he kept
very precise notes on exactly where he caught his specimens.
G
The attention to detail paid off. Beccaloni found that the mimicry rings
were flying at two quite separate altitudes. “Their use of the forest was quite
distinctive,” he recalls. “For example, most members of the clear-winged mimicry
ring would fly close to the forest floor, while the majority of the 12 species
in the tiger-winged ring fly high up.” Each mimicry ring had its own
characteristic flight height.
H
However, this being practice rather than theory, things were a bit fuzzy.
“They'd spend the majority of their time flying at a certain height. But they'd
also spend a smaller proportion of their time flying at other heights,”
Beccaloni admits. Species weren’t stacked rigidly like passenger jets waiting to
land, but they did appear to have a preferred airspace in the forest. So far, so
good, but he still hadn’t explained what causes the various groups of ithomiines
and their chromatic consorts to fly in formations at these particular
heights.
I
Then Beccaloni had a bright idea. “I started looking at the distribution of
ithomiine larval food plants within the canopy,” he says. “For each one I’d
record the height to which the host plant grew and the height above the ground
at which the eggs or larvae were found. Once I got them back to the field
station’s lab, it was just a matter of keeping them alive until they pupated and
then hatched into adults which I could identify.”

Passage 3:创新的差距
THE GAP of INGENUITY 2
Ingenuity, as I define it here, consists not only of ideas for new
technologies like computers or drought-resistant crops but, more fundamentally,
of ideas for better institutions and social arrangements, like efficient markets
and competent governments.
How much and what kinds of ingenuity a society requires depends on a range
of factors, including the society's goals and the circumstances within which it
must achieve those goals——whether it has a young population or an aging one, an
abundance of natural resources or a scarcity of them, an easy climate or a
punishing one, whatever the case may be.
How much and what kinds of ingenuity a society supplies also depends on
many factors, such as the nature of human inventiveness and understanding, the
rewards an economy gives to the producers of useful knowledge, and the strength
of political opposition to social and institutional reforms.
A good supply of the right kind of ingenuity is essential, but it isn't, of
course, enough by itself. We know that the creation of wealth, for example,
depends not only on an adequate supply of useful ideas but also on the
availability of other, more conventional factors of production, like capital and
labor. Similarly, prosperity, stability and justice usually depend on the
resolution, or at least the containment, of major political struggles over
wealth and power. Yet within our economics ingenuity often supplants labor, and
growth in the stock of physical plant is usually accompanied by growth in the
stock of ingenuity. And in our political systems, we need great ingenuity to set
up institutions that successfully manage struggles over wealth and power.
Clearly, our economic and political processes are intimately entangled with the
production and use of ingenuity.
The past century’s countless incremental changes in our societies around
the planet, in our technologies and our interactions with our surrounding
natural environments have accumulated to create a qualitatively new world.
Because these changes have accumulated slowly, It’s often hard for us to
recognize how profound and sweeping they've. They include far larger and denser
populations; much higher per capita consumption of natural resources; and far
better and more widely available technologies for the movement of people,
materials, and especially information.
In combination, these changes have sharply increased the density,
intensity, and pace of our inter actions with each other; they have greatly
increased the burden we place on our natural environment; and they have helped
shift power from national and international institutions to individuals and
subgroups, such as political special interests and ethnic factions.
As a result, people in all walks of life-from our political and business
leaders to all of us in our day-to-day——must cope with much more complex,
urgent, and often unpredictable circumstances. The management of our
relationship with this new world requires immense and ever-increasing amounts of
social and technical ingenuity. As we strive to maintain or increase our
prosperity and improve the quality of our lives, we must make far more
sophisticated decisions, and in less time, than ever before.
When we enhance the performance of any system, from our cars to the
planet's network of financial institutions, we tend to make it more complex.
Many of the natural systems critical to our well-being, like the global climate
and the oceans, are extraordinarily complex to begin with. We often can't
predict or manage the behavior of complex systems with much precision, because
they are often very sensitive to the smallest of changes and perturbations, and
their behavior can flip from one mode to another suddenly and dramatically. In
general, as the human-made and natural systems we depend upon become more
complex, and as our demands on them increase, the institutions and technologies
we use to manage them must become more complex too, which further boosts our
need for ingenuity.
The good news, though, is that the last century's stunning changes in our
societies and technologies have not just increased our need for ingenuity; they
have also produced a huge increase in its supply. The growth and urbanization of
human populations have combined with astonishing new communication and
transportation technologies to expand interactions among people and produce
larger, more integrated, and more efficient markets. These changes have, in
turn, vastly accelerated the generation and delivery of useful ideas.
But—and this is the critical "but"——we should not jump to the conclusion
that the supply of ingenuity always increases in lockstep with our ingenuity
requirement: While it's true that necessity is often the mother of invention, we
can't always rely on the right kind of ingenuity appearing when and where we
need it. In many cases, the complexity and speed of operation of today's vital
economic, social, arid ecological systems exceed the human brains grasp. Very
few of us have more than a rudimentary understanding of how these systems work.
They remain fraught with countless "unknown unknowns," which makes it hard to
supply the ingenuity we need to solve problems associated with these
systems.
In this book, explore a wide range of other factors that will limit our
ability to supply the ingenuity required in the coming century. For example,
many people believe that new communication technologies strengthen democracy and
will make it easier to find solutions to our societies' collective problems, but
the story is less clear than it seems. The crush of information in our everyday
lives is shortening our attention span, limiting the time we have to reflect on
critical matters of public policy, and making policy arguments more
superficial.
Modern markets and science are an important part of the story of how we
supply ingenuity. Markets are critically important, because they give
entrepreneurs an incentive to produce knowledge. As for science, although it
seems to face no theoretical limits, at least in the foreseeable future,
practical constraints often slow its progress. The cost of scientific research
tends to increase as it delves deeper into nature. And science's rate of advance
depends on the characteristic of the natural phenomena it investigates, simply
because some phenomena are intrinsically harder to understand than others, so
the production of useful new knowledge in these areas can be very slow.
Consequently, there is often a critical time lag between the recognition between
a problem and the delivery of sufficient ingenuity, in the form of technologies,
to solve that problem. Progress in the social sciences is especially slow, for
reasons we don't yet understand; but we desperately need better social
scientific knowledge to build the sophisticated institutions today’s world
demands.
