WILD,
TOTALLY WILD

first published in September, 2003.
The ironic Russian idiom "wonder in feathers" in title means any nonsensical
and ridiculous thing.

Prediction
of the future is ungrateful occupation. The most popular, but also the most
abuse in public TV presenters are weather forecasters. Their forecast should
precisely describe changes of weather in the nearest day, but it only occasionally
coincides with a next day view from the window.
It is much easier to predict the events will take place after 5 million, 100
million or even 200 million years. There will be nobody to check up a prophecy.
Therefore numerous collective of creators of book, Internet site and, probably,
a computer series “The Future is Wild: a natural history of the future” turned
out in very advantageous position. Besides the forecasts submitted in this
book, “base exclusively on science” according to authors, and authors are burdened
with various ranks and degrees. However all the same it is possible to make
sure of something: there happened almost everything that could happen for almost
four billion years of existence of life on Earth. By the way, authors of “The
Future is Wild” also permanently address to the past, whence take both giants
insects and a climate of the future Pangea-2 supercontinent. To tell the truth,
they use such adoptions rather clumsily. For example, it is told about a climate
of Pangea-2, to which present day continents should merge after 200 million
years (possible), that such event “never happened on Earth during all its history”.
“Inside the continent, thousand kilometers far from ocean, the fruitless Central
Desert lays. Here the average temperature changes from +50°С in summer up to
–30°С in winter...” So, and what never-happened things are here? All this is
literally copied from the book “Pangea: evolution of supercontinent and its
consequence for Earth paleoclimate and conditions of sedimentation” (1994),
also with gross blunders. 220 million years ago the significant part of Pangea
was located near the South Pole, and Pangea-2 should appear in equatorial zone;
that assumes not so severe climate, not mentioning the fact that climate and
first of all humidity in depth of continent depend not only on oceanic processes,
but also on species structure of algae living in ocean and character of forests
growing on land. Therefore it had changed so sharply from the end of Carboniferous
up to middle Triassic, and everything happened within the borders of the same
Pangea!
GREAT BLUE WINDRUNNERS, the descendants of recent cranes, till the next 100 million years will acquire the second pair of wings in order to maneuver at low speed.
FLISHES, that will descend from cod fishes, will master flight. For this purpose its pectoral fins will turn to wings. To have an opportunity for flish to fly up from water surface, its tail fin will change the structure becoming like whale’s one.
* Famous Soviet and Russian sci-fi
writers. The mentioned book “Monday begins in Saturday” is the humoristic
novel with elements of fantasy and
folk tales - translator’s note. |
Even for scientist authors all these factors appeared too
difficultly to envisage, therefore their future is more similar to the picture
described by Arcady and Boris Strugatsky* in their book “Monday begins in Saturday”:
“…any people dressed only partially had been permanently met: for example,
in green hat and red jacket on naked body (and no more); I was confused until
I had recalled that some authors are in the habit to write something like “door
opened, and on the threshold the harmonous muscled man in shaggy cap and dark
glasses had appeared”. It’s very exact characteristic of monsters of “The Future
is Wild”.
Each monster, even most plausibly fabricated, is brought up by authors in hothouse
conditions of incubator. In real inland communities it would not appear any
chance to appear to them. In Earth history the period of huge arthropods also
took place: approximately 320 million years ago dragonflies of 80 centimeters
wingspan flied, opilionids on half-meter legs walked, two-meter long millipedes
crawled. To make such picture a reality at least two factors had worked: absence
of competitors from the part of vertebrates at them and the increased level
of oxygen contents in atmosphere. Outside of dense oxygen-rich atmosphere the
respiratory system of overgrown arthropods will not work. But when running,
climbing and flying vertebrates settled on land, any changes in composition
of air (for example, at the end of Cretaceous period – the beginning of Cenozoic
era) did not help insects and their relatives any more. They will not help
also in the future. We don’t mention also that authors had easily and cheerfully
bypassed a problem of occurrence of superfluous oxygen. In Carboniferous about
which we speak, surplus of oxygen had been formed due to failure in circulation
of organic substances: chemical compounds appeared, which had been too hard
for former destructor organisms, and new groups of destructors, probably, had
not appeared. After their appearing “superfluous” oxygen had been quickly called
for oxidation of decomposed organic material. In the future the similar concurrence
of set of the events favorable for giant arthropods seems too incredible. It
hardly is worthy to expect of the appearing of any monster wasps even after
100 million years.
* Translator’s note for English readers: it is the phrase from humoristic monologue about the price of crayfish: “Yesterday’s ones were large, but cost five roubles. And today’s ones cost three roubles, but they’re small. But they are today”. |
Equally easily authors draw the reef community of 100-million-year “futureness”. And it is again without any look back at the past. “Futurist” biologists imagine new reef system this way: increase of the contents of nutrients favours to flowering of red algae, and overgrown nudibranch mollusks pollinating them develop, serving as a food for siphonophoras (that had “cost of five roubles, but yesterday”*). Actually the increased contents of nutrients results in abundance of phytoplankton which intercepts them at benthic communities (including algae) and simultaneously, breeding in huge amounts, lowers the water transparency. Therefore reeves in such periods are building by sponges – filtrating organisms not requiring for good light exposure, but not by calciferous algae. Red algae with strongly expressed sexual process exist not less than 1,2 billion years; for this time they have not got flowers; they will not blossom also in next 100 million years. Flowers are necessary for ground plants which should be pollinated outside of water environment. Large durophagous predators (“phage” in Greek means “devourer”, and first half of word means ones had not manage to evade from them) are really characteristic for time of largest reeves. But for this purpose the ecosystem should consist of multiply species which are built in longest chain where each subsequent link is larger and eats representatives of the previous smaller link. As a result right at the end of chain we receive an armoured fish of 9-meter length (380 million years ago), 14-meter ichthyosaurus (200 million years ago) or the favourite character of film “Jaws” (50 million years ago).
After next 200 million years squids will move on land and will turn to SQUIBBONS. They will move tumbling on the ground, but eyes located on muscled stalks will constantly stay in centre of gravity at such tumbling and will always look forward. Squibbons will live in groups and build rather simple nests on top tree branches. By their intelligence they’ll be closest to humans.
And any monster taken into account appears the paper tiger.
Well, by what reason cephalopods will crawl on land if it had not happen 400-420
million years ago? And you may see they also had not competitors on land there,
and shell serving as a support and damp shelter in case of drying, was at them.
Octopuses more than 150 million years evolve to the direction of skeletonless
sea creatures which are already impossible to be rebuild to forest partisans.
How will the tortoise turn to the hundred-ton monster? Tortoises never increased
their weight over one ton. A problem of size is much more difficult to be removed,
than the carapace. Analogies to dinosaurs (the limited weight of which, by
the way, is estimated to 80 and even to 35 tons) are inappropriate here. Dinosaurs
at first had solved a problem of support and breath, and then began to increase
weight. Ancestors of tortoises had gone in other way: the carapace had formed
a framework protecting thorax from squeezing. Otherwise they could not walk
and breathe simultaneously. And protection is important, but by-effect of this
design. After disappearance of predators it will not be easier to breathe,
and the 120-ton armourless tortoise, besides eating up to 600 kg of vegetation
per day (why will this cold-blooded one consume so much?), is a strange invention
of the authors, considering themselves as experts in biomechanics and physiology.
And how to receive treelike forests from lichens at their rates of growth (no
more than 5 centimeters per year)? They are not casually distributed only in
places where they have completely no competitors, the higher plants. And again,
such thing hadn’t happened 420 million years ago when their contenders still
had not mastered land in full degree. Giant mushrooms, 70 centimeters in diameter,
had appeared then (and also had quickly came to naught), and treelike lichens
never appeared. Also it will not happen. Actively flying fishes will not appear.
Adaptations to flight arose repeatedly (insects, some thecodonts, pterosaurs,
nowadays living fan-tailed birds and lizard-tailed birds unrelated to them),
but always at overland organisms. Flight develops as strategy of those ones
who catches up. Above ocean open spaces, if to remove birds, nobody will be
hunted, and if to leave birds, the competition never will develop for the benefit
of fishes, the beginning flyers.
Authors of “The Future is Wild” had completely excluded from their constructions
also the fact that species evolve in communities instead of in themselves.
They had completely ignored also that in evolutionary transformations of any
group of organisms there are their own rules as Nikolay Vavilov has established
in the beginning of XX century. The history of fossil communities not casually
indicates that to change the extinct species very similar one usually comes,
and frequently related to it (but not any monster). This way rather steady
systems, existing millions years, are formed. Parallelisms in development,
which western scientists usually avoid to discuss (also not only in this book),
are peculiar to alive systems in general, in other words, to related groups
of organisms. In several lines of the certain group of reptiles key features
of mammals formed independently, also independently in other group of reptiles
attributes of birds gathered, and among gymnospermous plants attributes of
flowering ones did. Even features of man of modern type developed independently
in different lines of orthograde primates. All these laws prompt, for example,
that a niche of birds, under condition of their total extinction, will be occupied
by new feathery or scaly creatures arisen from skipping or tree-climbing reptiles,
but in any way not from fishes.
In essence, creators of “The Future is Wild” use exclusively images of modern
and prehistoric organisms, for what those ones are “dismembered” and as if
exchange their parts. However thus the level of development of organisms remains
constant and more – less modern. Though all history of development of life
on Earth testifies to constant increase of energy of all live beings. Russian
paleontologist Alexander Rautian rather exactly and wittily said that the Paleozoic
world, as opposed to Mesozoic one, moved at walk. For the last of 600 million
years not only speeds of movement of animals have increased, but also significantly,
especially during Mesozoic and Cenozoic, their ability to a filtration, processing
of deposits, an opportunity of protection and an attack has amplified, a variety,
both general (global) and local (within the limits of the certain communities)
has sharply jumped up. Probably, at the overcoming of present day ecological
crisis all these tendencies will renew also in the future. Authors had undertaken
to untwist the geological annals in return side: a congelation – Messenian
crisis (the shallowing of Mediterranean Sea) – Triassic Pangea, – having populated
the Earth of the future with the organisms of the past.
On the average creators of “The Future is Wild” had heaped up one gross blunder
to every page, not taking into account any small flaws. Like isolated South
America at the moment of extreme lowering of sea level. Or like the grassland
fires destroying trees to please to grasses. Excuse me, but what about scrubs
(thickets of trees and bushes) of Australia, where eucalypti are adapted to
survive in periodic fiery waves not worse as local grasses? Authors have slow
twisting rivers flowing on abrupt slopes, and pollen of plants flies from South
America to Australia against the wind direction. And the main reason of rising
of sea level was... the expansion of water at heating. And all glatio- and
tectonoeustasies are out of attention! (First of these terms connects change
of sea level to the condition of icecaps, and the second with the volume of
mid-oceanic ridges.) Unfortunately, the newest word in “science” had not get
any value, but meanwhile it is interesting to know, what volume of water can
be added due to its expansion.
Scenes of global extinctions also are too far-fetched. Last congelation, for
example, if it caused an effect to evolution of Homo sapiens, caused it only
to the side positive for it. It had allowed it to deal with other real competitor
for place on Earth – with Neanderthal man. It is surprising that Neanderthal
men were better adapted to life in frosty climate, but their small populations,
isolated as a result of approach of glaciers, were, probably, partly assimilated,
and generally exterminated by hordes of Homo sapiens which have intruded to
Europe. So, the danger of winterkilling threatens to it at the least degree.
By the way, we still live in ice age, and the science is not capable to give
the plausible forecast: will it become warmer or colder the nearest centuries.
Even if to assume, that carbonic gas is the basic heater of modern atmosphere
(not all scientists agree with it), the level of its contents in atmosphere
depends on set of the reasons: rates of orogenic processes, pattern of volcanic
activity, productivity of oceanic phytoplankton, species structure of phytoplankton,
features of ground vegetation, but not just of amounts of organic fuel burnt
by people.
Till only last five years each of these factors had taken the leading place,
but the clear picture of climate of the near future had not developed yet.
Forces and means of modern science are simply not enough for similar forecasts
.
It is possible to tell evidently only, that so power-intensive species, as
the human species is, can not exist for a long time because of limitation of
resources. Everything that people consume as a raw material is created by former
ecosystems in unique and frequently unrepeatable conditions. Sooner or later,
having lost the source of raw materials, the mankind is doomed. And only in
some thousand years no one ape species will live on Earth. From the stock of
feral cattle the ecosystem of grassland type (because grasses are more adapted
to present rather low contents carbon dioxide in atmosphere) will start to
restore. In human time semi-feral mustang horses have taken a place of bisons
in prairies, and also their own one in some extent (their horse ancestors lived
there). Ecosystems of tundra, taiga, semideserts and deserts will revive in
former condition. Congelations and warmings will shift their borders, but will
not cause any mass extinctions likewise they did not cause them in past (again
on contrary to statements of authors of the book). And if patches tropical
rainforest and reeves will be kept, they also will restore though in strongly
impoverished condition. But the only thing will never appear on planet is an
intelligent life.
