The migrating
Monarch butterfly is the only butterfly among thousands of species
that migrates. This frail creature flies some three and a half
thousand kilometres from Canada to Mexico every Fall. Since
they only live for about nine months, none is able to make the trip
twice.
Monarchs can clock up to sixty-five kilometres a day, going twice
as fast as a person can walk. However, a more typical average,
based on data collected from one swarm's trip from Ontario to
central Mexico, is twenty-four kilometres a day.
Recent work at Queens University in Canada has thrown some light
on the mystery of how Monarch's find their way. Scientists
built a flight simulator which was able to detect the Monarch's
preferred direction of flight. They concluded that Monarchs
use what they called "a sun compass" which enables them to
take account of the time of the day and then accurately orient
themselves using the position of the sun. They found that even
on a cloudy day Monarchs are able to use polarized light to tell
where the sun is and still get oriented.
By varying the time that the lights were turned on and off,
scientist were able to shift the internal clock of the Monarchs, and
change the setting of their sun compass so that they flew off
course.
So next time you see the beautiful Monarch, respect
its tenacity. Flying through many hazards, it still returns to
the place its parents visited the previous year.
MOVING BEYOND
MATTER
by Christopher Shennan
Monarch butterflies are not the only creatures that can be made
to fly off course. Humans have a long history of veering off
in the wrong direction, with some fatal flaw in their moral compass.
There is no shortage of evidence to prove this true. Just
open a newspaper, or turn on the TV, and one tragic story after
another, parades before our eyes. Domestic violence, arson,
robbery, murder, all demonstrate that multitudes of people in our
modern world no longer know the difference between right and
wrong. Or, if they do know the difference, they seem helpless
to readjust their moral compass. They consistently follow a
path that is harmful to themselves, those around them, and society
as a whole.
Perhaps, like the butterfly in the experiment, someone has
tampered with their sense of direction.
Are we going in the right direction? Maybe its time to
check our inner compass. It may be in need of calibration.
Scientist used artificial lights to temporarily readjust the
Monarch butterflies' sense of direction. Getting back under the
light of the sun would surely get them back on course. Remove
the false light, and the true light would guide them back.
Could it be that we've lost our moral bearings because we've been
following false lights? Manmade lights? Finding the True Light
is the only way of getting back on course. After all, it was
Jesus who said: "I am the light of the world. The
person who follows me will never live in darkness. He will
have the light that gives light."
