[net.origins] Isolation and Unique Species

eklhad@ihnet.UUCP (K. A. Dahlke) (04/15/85)

< I am an island >

	So often I have read words to the effect:
"All you have is some fossils, and carbon radiometric dating ... ".
Surprisingly, these comments typically receive very few rebuttals.
In my last article, I mentioned the substantial independent
biochemical evidence supporting evolution.
This evidence is ubiquitous, and simple reproducible experiments
repeatedly verify its existence.

	In this article, I shall briefly mention another major
branch of independent evidence, geography.
Although we cannot observe large-scale evolution in the laboratory,
our planet has provided many "experiments" for us,
in the form of isolated geographic regions (islands and lakes).
These isolated regions always contain unique species, related to
mainland life, but slightly modified.
I wish I could eloquently expound on this topic,
but I could never produce a better presentation than this week's
"Life On Earth" TV episode (PBS network).
If you missed it, watch for any rerunning thereof.

	How could new species appear in isolated regions if they didn't evolve?

	"Wait a minute!!" cries the creationist in desperation.
After all, evolutionary evidence rears its ugly head yet again, we must
bat it down, no matter how absurd the counterargument.
"There is a simple explanation.  Gawd created unique
species everywhere, and those on the mainland mingled and mixed.
When we got to the islands, we found some previously inaccessible species.
A simple uniform distribution of created species answers everything."
Long sigh of relief.

	I give a long sigh myself, but for other reasons.
The islands were not there when animals first appeared.
(I am not dealing with the "young earth" or "God is fooling our eyes" camps.)
Furthermore, the diversity of unique island species is highly correlated
with the island's time of isolation, and the number of niches on it.
Why should Hawaii have 4/5 of the world's drosophila species?
It doesn't contain 4/5 of the world's land area.
Rather, it provided many different environments,
and isolation (not many fly eaters).  These short-generation animals quickly
evolved into a dizzying number of species.
Why were 90% of Hawaii's indigenous plants unique?
Why are island animals (e.g. turtles) larger than their mainland counterparts?
Why do birds become large and flightless on islands.
Is flying expensive, and hard to justify without cats around,
or did God just snap his/her fingers again.
Why does evolution explain most of these phenomena.
Why can creationism explain none of this,
without resorting to coincidence, or continual divine intervention (unlikely).

	The "Life on Earth" series has given me valuable
insight into the evolutionary process.
More important, I am again reminded
of the complexity and diversity of life on our planet.
The beauty of a bird in flight necessarily
captivates evolutionists and creationists alike.

As a biochemist interested in evolution I have followed this net with some
interest for the past several months.  This is the first mention I have 
seen of what I consider the strongest evidence available (now) for the 
evolution of species by natural selection.  The Hawaiin Drosophila that
Karl mentions are closely related to each other and somewhat less closely
related to other Drosophila species.  The interesting point is that a 
mechanism now exists to explain rapid speciation in the genus Drosophila.
I am not sure of my ability to present this to the net, but I will make an
effort anyway.

After he posted this, I thought "This was how it came to Darwin".
You surround yourself in nature, and the patterns hit you over the
head.  And so I ask, are there any creationist naturalists?  I suspect
there are not, as few seem capable of seeing beyond the gilt edges
of their bibles.  And they are not alone in that myopia--many scientists
can't see beyond their sacred tomes either.  But those who can, they
stand the world on its ear.

OK, Paul, just what is *your* explanation of this?

No, I don't.  I meant what I said, viz. "what creationist actually
uses this argument?"  No acrimony implied.

Yes, there are (and have been) numerous creationist naturalists, as has been
pointed out in other notes.  They can perceive the patterns also, though
modern ones seldom look for patterns on as grand a scale as Darwin did.
(For example, there are large numbers of creationist birdwatchers, and
some creationist taxonomic specialists.)  And their work can be useful
where the patterns prove widespread and consistant.

Maybe.  Or maybe someone could actually come up with the creationists
who make this argument.  Or maybe someone could just admit that it's
a straw man, and quit circling around the question.

I understand how evolution explains most of these, but I have to ask
about one:  what is the explanation for larger animals on islands
than on the mainland?

The original argument is FOR evolution. It is true that a straw man was
raised as a posible creationist response, but if you don't want to use
that argument what argument DO you want to use. The point is not that
creatonist use that argument, but that they don't have a better one (or
if they do, they are keeping it secret :-).

Predation is an important selective pressure.  If larger animals tend to
be preyed upon more successfully (because they are easier to spot, can't
burrow as well, or whatever), there will be selection to keep a species
small, despite contrary pressures (such as larger animals being able to
defend territories more effectively.)

Move the animal to an island where there are no predators for the animal,
and selection for larger size can act freely.

You're the only one who has been circling around the question, Paul.  We
really don't care if any creationist ever made an argument similar to the
one above.  We've just been trying to get you (or some creationist) to
answer the question.  Is that so much to ask?  In case you've forgotten
what the question was (though that doesn't seem likely since you've gone
to such great lengths to avoid answering it.), I'll attempt to reiterate
it.  This phenomena exists:  Isolated habitats often support a large 
variety of species which are found nowhere else.  There is a correlation
between the number of unique species in an isolated habitat and the length
of time that habit has been isolated.  Obviously, this phenomena is
easily explained with the use of evolution.  Can creationists explain it?
If so, how?  No strawmen here, Paul.

  This is really not a very big problem for creationists. Animals have
  been known to migrate over very long distances. "The Migration of Animals",
  L.H. Mathews.
  As a creationist who believes in catastrophist geology (The Flood), I would
  suggest that after leaving the Ark, many animals migrated into different
  parts of the world into places that were better suited for them
  to live. Or, many animals may have migrated because of an over abundance
  in one particular area. A. Franklin Schull, an evolutionist, makes
  this point in his book, "Evolution", on page 60. And in "Genes, Genesis,
  and Evolution", John W. Klotz, (an evolutionist), states concerning
  the fact that many marsupials and monotremes are found nowhere in the
  world except Austrailia, "It may be that these forms have become extinct
  in Asia and along tha Malay Peninsula. Possibly they were able to live
  in some of these areas for only a short time and travelled almost
  immediately to those places included in their present range." p. 226.

  Rachel L. Carson, "The Sea Around us" page 89, ...riding on the winds,
  drifting on the currents, or rafting in on logs, floating brush, or trees,
  the plants and animals...arive from the distant continents.

  Of course, these facts can not prove either creation or evolution, but
  let it be pointed out creation is not at odds or contrary to what we
  know to be true concerning the behaviour of animals and their habitats.

I suppose that it's just coincidence that the animals that happened
to migrate to islands are remarkably different that those that
happened to migrate to continents?

This is very typical of the quality of creationists "science"
- no analysis, no attempt to explain phenomena - just a half-baked
effort to reconcile reality with their own particular religious
phantasy.

    I see.  And all of the species which are found in isolated habitats and
nowhere else just got off the ark, traveled halfway around the world or so,
directly to their isolated habitats (building boats if need be), leaving no
offspring anywhere else, and established themselves where they were supposed
to be.  Sounds real likely to me.
    Since you've admitted to being a believer in the flood, I can't resist
asking again:  where did all of the water come from?  Where did it go?  A
second and third act of special creation?

	I (and others) have been accused of presenting "strawman"
creationist explanations for isolated speciation.
Clearly, we do not fabricate these explanations.  I ask you, what choice
do we have  (judging from the above)?
At least Paul (and others) give *some* thought to their arguments
before posting them to the net.
Could someone more knowledgeable than I do me a favor,
and compute a rough lower bound for the number of species that have lived
in the last 10,000 years.  Since species never evolve :-),
they must have *all* been present on the ark.  Including, of course,
enough food for 40 days, isolation chambers so they don't eat each other,
isles providing access to the animals, etc.  350 cubits just won't make it.
Of course, Noah really should take 1,000 of each animal, to insure
a sufficient gene pool for the success of each species.
Oh but I keep forgetting, the animals have devolved, and they
didn't have genetic imperfections 10,000 years ago :-).
So we will give your "scientific" theory the benefit of the doubt, and allow
two from each species.  Would someone calculate how
big the ship has to be to hold all the animals,
and how long it would take to construct such a vessel, given the technology
of the day?  Of course I haven't mentioned the other problems:
where did the water come from, where did it go, how did the animals reach
their geographically distant isolated regions, did Noah take plants as well,
how did he collect all the species, how can an animal travel half way around
the world without leaving a trace or offspring, etc etc etc.

This is almost as bad as the "speed of light is decreasing over time"
argument presented at a recent creationist talk here at ATT-BL.
It was an attempt to reconcile a young world with astronomical observations.
I shall not even respond to the "evidence of design" garbage.
Come on people, God won't send you to hell for using your brains.

  Much more likely than the animals coming from an amoeba. More likely

Which reminds me of another "Noah's Ark" question that I have never
seen answered by Creationists.  There are certain diseases, such as
smallpox, that have no natural reservoirs, and which confer lifelong
immunity upon those unfortunate enough to have contracted them once
but fortunate enough to have survived.  Would some Creationist care
to tell us how smallpox itself survived the Flood?  I remind everyone
that the way smallpox has been wiped off the face of the Earth (except
for artificially maintained samples in a few laboratories) was by
finding every case and vaccinating everyone who was exposed to it.
A similar principle would have applied in the Ark.  The disease
could not have survived in the small population consisting of Noah and
his family.  Everyone would have gotten it, and become immune.  The
virus would have had no hosts and would have died out.

If you threw a hundred thousand dice and noted the combination that came up,
then asked someone what is the likelihood of that particular combination
arising in one throw of the dice, they'd probably dispense with the math and
say simply, yet emphatically, "Not Very Likely".  And they'd be quite right.
But it's extremely likely (certain, in fact) that *some* (roughly) equally
unlikely combination would arise.

If you took an organic soup with a hundred billion "dice" in it and noted
what particular arrangements of the "dice" formed, ... (you get the drift).
The point is: in a dynamic environment *some* arrangement (for want of a
less design-implying word) will show.  And who's to say that the one that
did show is the only one that would have resulted in life?  It may (or may
not) have been the only one that resulted in Life As We Know It.  But it may
well be the case that *most* of the combinations would've resulted in *some*
kind of creature who, given enough time, could've looked back and said "HA.
What's the 'likelihood' of life [as we know it] arising from SOUP?!" Then
again, it may not.  The point here is to remind you to be careful of "like-
lihood", because it's not just likely, but *certain*, that *something* would
have arisen.

>  Please, don't be silly! Animals can't build boats!

How did animals who can neither swim nor build boats, like kangaroos, get
from Mount Arrarat (sp?) to Australia (given, of course, that kangaroos
didn't evolve from animals that *could* swim or build boats :-) )?

I thought we might add a few questions for the 'Ark' theory:

1.  What did the carnivores eat after leaving the ark?

2.  For that matter, what did the vegetarians eat if plants were
    preserved as seeds and hadn't grown to be edible yet?

3.  Do you really expect anyone to believe (without any evidence)
    that all the animals migrated to the different continents?
    This implies that the penguins swam to the pole, kangaroos,
    koalas, etc. swam to Australia.  And, why are there no kangaroos
    or many other Austrailian animals elsewhere?  Did all the kangaroos
    swim over as a group?  Or maybe the first two did their swim before
    they had any offspring?

4.  Why are creationists seemingly unfamiliar with previous (pre-evolution)
    creationist work on the Ark theory?  (Athanasius Kircher (late 1600's)
    Carl Linnaeus (late 1700's), Eberhard Zimmermann (late 1700's), 
    Philip Sclater (mid 1800's), Edward Forbes (mid 1800's))  Most of these
    pre-evolutionary creationists have already wandered through all the dead
    ends of the Ark theory over a century ago, yet modern creationists seem
    to be exploring them anew, seemingly unaware of previous research in
    this area.

Your computation of carrying capacity was based on volume, not floor space.
By floor space, the result is close to exactly what you estimate as needed.
But in real life, you cannot pack other animals as closely as sheep.  Even
if you sort them to size.  Looks like you need another miracle.

Of course, that's accepting on face value the claim of 300 cubits for the
ark.  If the ark existed, that claim would be probably as exaggerated as
the ages of Noah and his ilk.  The size stated in the Bible is about half
the size of modern super tankers.  It's likely bigger than any wooden
ships ever built, let alone several times bigger than ships of that period.
And we are expected to believe that Noah and family built it by themselves?
Looks like you need another miracle.

Trips in cattle-cars are brief, so that the animals need little care.  Even
if all the natural hibernators and estivators did their thing, the ark
wouldn't have room for 40 days food for the remaining thousands of animals.
Not to mention all the different kinds of food.  Not to mention the labor
involved in feeding several thousand animals.  Looks like you need another
miracle.

For every thirty feet of water the "canopy" held, it would have increased
pressure on the surface of the earth by another atmosphere.  How many
thousand feet of water were there in your "vapor canopy"?  And what about
transmission of light through it?  The sun must have looked pretty dim after
shining through all that liquid or vapor.  Sounds like you need more miracles.

But why would only marsupials migrate to Australia?  It sounds as if more
miracles are required to direct ONLY certain animals to certain localities.
We're talking more than a hundred marsupial species, and no placental
species (except bats.)

Science has spent the last few hundreds of years shedding the very
superstitious prejudices you are trying to reinstate.

Show us the geological evidences that gradulism cannot explain, and
"flood theory" can.

The fact is, that with enough miracles, you can explain anything in the
bible, and make it consistant with the evidence we have today.  "Oh, god
pushed up mountains after the flood."  "Oh, god planted evidence in the
fossil record."  But adding on miracle after miracle, you gradually build
a tottery ediface of epicycles pushed by angels that eventually will
topple under its own clumsy artifice and by supplanted by a scientific
explanation.  That's what happened to flood geology more than a hundred
years ago, just as the Ptolomeic universe was displaced by the Copernican
several hundred years earlier.

CJC@psuvm.BITNET (05/25/85)

     
     
     
     
  Dan Boskovich recently posted a lengthy article under this heading;
those who read it may be interested in knowing that everything in Dan's
article came from "The Genesis Flood" by John C. Whitcomb, Jr., Th.D.
and Henry M. Morris, Ph.D.,  (Copyright 1961.)   The quotations Dan
gave are exactly as they appear in this book and all non-quoted ideas are
very close paraphrases.  I can understand not wanting to type in lots and
lots of bibliographic references, but when the entire article comes from
just one book (with direct quotes even, he had to have the book beside
him when typing) I think the source should be named.
  I was quite disappointed at the limited source of information of the only
person who really tried to reply on this topic; the book is very strongly
religious (many chapters are entirely biblical interpretation - Whitcomb
is, after all, a professor of theology), and it attempts to explain
everything but so briefly that it explains nothing satisfactorily.  The
question of how was vegetation reestablished after the flood is dealt with
in a few paragraphs about the possible survival of plants in floating
masses (rafts) of vegetation, or by chance shallow burial, or as seeds
included in the ark in food supplies, then a longer description of the
olive tree which is apparantly a tough adaptable plant which reproduces
readily from cuttings.  Perhaps Dan could find a reference which explains
the survival of the many species of cactus which are adapted only to dry
conditions; this reference should also explain the geographical distribution
of cactus - according to my gardening and wild-flower books, the many
species of cactus are, with possibly one exception, confined to the
desert regions of America. The deserts of all other parts of the world
have distinctly different vegetation.  And then he could consider the
low-bush blueberry which is extremely difficult to propagate either by
seeds or by cuttings. The plants spread by underground stems, and I read
some years that on the basis of the slow rate of spreading some of the
largest clumps were in contention for the oldest living plant on earth.
   As for the distribution of animals, Morris and Whitcomb go on for some
time on migration possibilities, then end with this paragraph:
   "The more we study the fascinating story of animal distribution
   around the earth, the more convinced we have become that this vast
   river of variegated life forms, moving ever outward from the Asiatic
   mainland, across the continents and seas, has not been a chance and
   haphazard phenomenon. Instead, we see the hand of God guiding and
   directing these creatures in ways that man, with all his ingenuity,
   has never been able to fathom, in order that the great commission to
   the postdiluvian animal kingdom might be carried out, and "that they
   may breed abundantly in the earth, and be fruitful, and multiply
   upon the earth."  (Gen. 8:17)"
     
In other words, the koala, the wombat, the bandicoot, the duck-billed
platypus, and all the other marsupials are in Australia, and nowhere
else, because God wanted them there; and rabbits and deer - good travelers
excellently suited to Australia and New Zealand - were not there because
God did not want them there (and he was right, wasn't he, see how much
trouble they've caused :-))
   If this net is for discussing the *SCIENTIFIC* origins of the present
world, then please let us have no more appeals to "The Genesis Flood".

For science to be truly objective,

1) look at data
2) form theory
3) test theory
4) repeat ad infinitum

Not,

1) look at certain book
2) look at data
3) form theory that does not contradict (1) and least contradicts (2)
4) don't bother testing theory
5) argue ad infinitum

	Actually, there is even a more significant problem. Australia
is isolated from the Middle East(where the ark is supposed to have
been) by a large expanse of water. How did the kangaroos *cross* this
water? Did they build themselves boats?!:-) or what? And armadillos
being an American group had to cross an even larger water barrier,
the Atlantic Ocean, which doesn't even have many islands to be used
for island hopping! This is why many 19th century creationists(before
Darwin) postulated multiple centers of creation. Of course this
required the elimination of the universal flood, or having most
animals created anew after the flood with only those in the Middle
East being saved by Noah. Come on, if you want to convince anyone
please come up with a believable mechanism for current biogeographical
patterns!

Dan, why would you use such old figures?  Recent estimates (1980's, I can't
quote the source [I know that's taboo] but I'm positive of this) put the
number of species of BEETLES at circa THREE MILLION.  This appears to be
a great deal more than the total (one million) of your (Mayr's) figures.
