Proponents of intelligent design, which holds that a supreme being rather
than
evolution is responsible for life's complexities, have long criticized
science
for not being able to explain some natural phenomena, such as how bees fly.
Now scientists have put this perplexing mystery to rest.
Using a combination of high-speed digital photography and a robotic model of
a
bee wing, the researchers figured out the flight mechanisms of honeybees.
"For many years, people tried to understand animal flight using the
aerodynamics of airplanes and helicopters," said Douglas Altshuler, a
researcher at California Institute of Technology. "In the last 10 years,
flight biologists have gained a remarkable amount of understanding by
shifting
to experiments with robots that are capable of flapping wings with the same
freedom as the animals."
Exotic flight
The scientists analyzed pictures from hours of filming bees and mimicked the
movements using robots with sensors for measuring forces.
Turns out bee flight mechanisms are more exotic than thought.
"The honeybees have a rapid wing beat," Altshuler told LiveScience. "In
contrast to the fruit fly that has one-eightieth the body size and flaps its
wings 200 times each second, the much larger honeybee flaps its wings 230
times every second."
This was a surprise, because as insects get smaller, their aerodynamic
performance decreases. To compensate, they tend to flap their wings faster.
"And this was just for hovering," Altshuler said of the bees. "They also
have
to transfer pollen and nectar and carry large loads, sometimes as much as
their body mass, for the rest of the colony."
Try this!
In order to understand how bees carry such heavy cargo, the researchers
forced
the bees to fly in a small chamber filled with a mixture of oxygen and
helium
that is less dense than regular air. This required the bees to work harder
to
stay aloft and gave the scientists a chance to observe their compensation
mechanisms for the additional toil.
The bees made up for the extra work by stretching out their wing stroke
amplitude, but they did not adjust wingbeat frequency.
"They work like racing cars," Altshuler said. "Racing cars can reach higher
revolutions per minute but enable the driver to go faster in higher gear.
But
like honeybees, they are inefficient."
The work, supervised by Caltech's Michael Dickinson, was reported last month
in the Proceedings of the National Academy of Sciences.
New aircraft designs?
The scientists said the findings could lead to a model for designing
aircraft
that could hover in place and carry loads for many purposes such as diaster
surveillance after earthquakes and tsunamis. They are also pleased that a
simple thing like bee flight can no longer be used as an example of science
failing to explain a common phenomenon.

Proponents of intelligent design, or ID, have tried in recent years to
promote
the idea of a supreme being by discounting science because it can't explain
everything in nature.
"People in the ID community have said that we don't even know how bees fly,"
Altshuler said. "We were finally able to put this one to rest. We do have
the
tools to understand bee flight, and we can use science to understand the
world
around us."

I remember people claiming that according to the principles of
aerodynamics, honeybees should not be able to fly. Yet they do. This
article shows how. Science scores over superstition again.

As I understand it, this whole myth comes from a long standing
misquote. Someone, I forget who, did the sums that showed that a honey
bee could not fly according to a rigid wing model - and he then went on
to investigate more complex models. AFAIK, no-one ever said that the
laws of aerodynamics etc. precluded them from flying.

That is correct. The whole bumbebee thing is on snopes.

I recall many references to that mistake. The fact is that they do fly
so how can aerodynamics be violated?
