News: Charles Darwin: More than the origin.
Ye Old One
Two articles about Darwin cap off his bicentennial by providing new
historical perspectives
http://www.eurekalert.org/pub_releases/2009-12/ajob-cdm120909.php#
Although Charles Darwin is most well-known for his book On the Origin
of Species, in which he described the process of natural selection, he
greatly contributed to many specific fields within biology. As the
bicentennial anniversary of Darwin's birth comes to a close, the
December issue of the American Journal of Botany presents two papers
exploring botanical history before the time of Darwin, Darwin's
contributions to botany, and what scientists have discovered in the
subsequent years following Darwin's first presentation of his many
provocative ideas to the scientific community.
In "The 'Sensational Power' of Movement in Plants: A Darwinian System
for Studying the Evolution of Behavior," Dr. Craig Whippo and Dr.
Roger Hangarter discuss Darwin's research on plant movement
(http://www.amjbot.org/cgi/content/full/96/12/2115). When Darwin first
presented his theory of evolution, many opponents of the theory argued
that evolution could not account for the acquisition of behavioral
traits. Darwin believed that if he could present a materialistic basis
for behavior, he could then explain how evolution acted on it. He used
plant movements to test his theories of the evolution of behavior,
and, as in many other areas of biology, Darwin's plant physiology
research contributed to a paradigm shift in our understanding of the
biological basis of insect, plant, and microbial behavior.
While studying carnivorous sundew plants, Darwin was shocked to learn
that the plant was more sensitive to touch than human skin and could
even distinguish between objects. Darwin's many experiments convinced
him that plants were actively responding to the environment and that
their movements were not a passive consequence of the environment
acting on the plant. Darwin attempted to explain all plant movements
as modified forms of circumnutation, a process whereby a plant or
plant part moves in repeated revolving arcs. He believed that these
movements occur as a result of the plant's response to external
stimuli, which are sensed in the root and shoot apices. Darwin
advanced the notion that these influences are then transmitted to
other parts of the plant. Although research has since shown that this
explanation of plant movement is not complete, Darwin's idea of a
transmittable influence in plants led to the eventual discovery of
auxin, a hormone that plays an essential role in many growth processes
in plants.
"Plant biologists often cite Darwin for pioneering the study of plant
movements and discovering that a transmissible substance was involved
in many plant movements, later found to be auxin," Hangarter said. "In
researching the material for this paper, we were surprised to learn
the extent to which Darwin's predecessors and contemporaries had
contributed to the same areas of study with little recognition.
However, what struck us the most was to learn that his plant movement
studies were largely motivated by his desire to understand how complex
animal behaviors could evolve through natural selection."
In the AJB's second article, "'The Orchids Have Been a Splendid
Sport'�An Alternative Look at Charles Darwin's Contributions to Orchid
Biology," Dr. Tim Win Yan, Dr. Joseph Arditti, and Dr. Kenneth Cameron
explore Darwin's observations on orchids
(http://www.amjbot.org/cgi/content/full/96/12/2128). Jacob Breynius
once stated, "If nature ever showed her playfulness in the formation
of plants this is visible in the most striking way among the
orchids�Nature has formed orchids in such a way that, unless they make
us laugh, they surely excite our greatest admiration."
Darwin's book The Various Contrivances by Which Orchids are Fertilized
by Insects, was his first to be published following On the Origin of
Species. In this book, Darwin discussed various peculiarities of
orchids he observed, and he stated that although some people might use
these peculiarities as examples of new organs specially created, a
true understanding of these organs shows that they are modified forms
of organs found in other plants. Perhaps due in part to the fact that
evolution provides the framework that allows us to understand the
living world, much of Darwin's research that was not explicitly
related to his theory of evolution was nonetheless used to justify
evolution by natural selection or was based on the premise of the
theories and mechanisms.
Darwin's explorations into orchids also led him to state that orchid
pollen has an "injurious and poisonous" effect on flowers. What Darwin
did not know at the time was that one of the substances in the pollen
that plays a role in the death of the orchid flower is auxin, as noted
in the Hangarter article. Not only can much of our understanding of
the natural world be traced back to Darwin, but also much of our
current botanical knowledge.
"What impressed me about Darwin's work with orchid is how much more he
studied and understood about orchids than just pollination," Arditti
said. "But what amazed me was his prescient statement that orchid
seeds depend on a fungus for germination. He made this statement on
what seems to have been either deep understanding or little more than
a hunch long before the French botanist No�l Bernard actually
discovered orchid mycorrhiza."

First animals can hear frequencies that man cannot.
Now, plants are more more sensitive to touch than human skin.
IOW science still has a lot to learn about "The Origins Of Species"
How about THAT.

Then why do you try to keep hammering parts tht don't fit into places
they don't fit?

Nope, man can "hear" frequencies far beyond any other animals can
possibly hear naturally.

So?

Funny that, Darwin knew it over 150 years ago. What has creationism
learnt in that time? Zilch.

You should be shunned, in fact you are by a number of people. However,
that would be the easy way for you to escape and not face up to at
least these two examples of your past stupid claims.
1) That the actor Paul Newman was a creationist...
[Message-ID: <e3xDk.44738$De7....@bignews7.bellsouth.net>]
2) That "Dr." Kent Hovind has made lots of *scientific* discoveries...
[Message-ID: <3Olyk.31543$Ep1....@bignews2.bellsouth.net>]
Now, all you have to do is justify them, with evidence of course, or
finally admit you were a fool to make them.
Or are you just going to go on being a cowardly lying troll?

That's not shunning, that's making a huge display. It's clear whoever
caused you to do this got to you big time.
Hint: If you are truly shunning someone you pay them no attention whatever.
Now if you wrote "hated" or "feared" that would be truthful.
