Honey Bees
by Robert Doolan
Imagine you are a honey bee. You leave your hive one tine Spring
morning and scout
around until you notice a field full of new flowers in bloom. The
food back in your hive
which the 15,000 bees in your colony have fed on through the winter,
has been getting low. But now in this field you have found a new
food supply. So you till your honey sac with nectar and fly the 250
metres back to your hive. The other bees do not yet know where to
find the blooms you have discovered. Your brain is only the size
of a pinhead but it is obvious that it you are to utilize this new
food source you will need help. Before summer arrives, your colony
could number more than 80,000 bees. But the little bit of pollen
and nectar you would collect in each halt kilometre round trip could
see your colony starve before each member was ted. So how do you
tell the other bees in your hive where to find the blossoms you have
discovered? Artistes?
In the early 1900s, an Austrian naturalist named Karl von Frisch
puzzled over this curious problem. Fascinated by the ways honeybees
worked together, von Frisch began some
revealing studies into the life of these little creatures. What did
he find? He found that one of the most remarkable characteristics
of bees is the way they communicate. In fact bees have one of the
most extraordinary means of communication in the insect world. Von
Frisch discovered that bees express themselves not only by feeling
and tasting, but also by dancing. To identify the location of a food
source too distant from the hive to be smelled or seen by the other
bees, the scout does a dance on the honeycomb inside the hive. Other
bees gather around and closely follow the dancer. They imitate her
movements (all dancing worker bees are female), and note the fragrance
on her of the flowers from which the dancer gathered the nectar.
If the new food source is nearby, say within about 50 metres of the
hive, the bee does a circular dance on the surface of the honeycomb.
She moves around two or three centimetres (an inch or so) then circles
in the opposite direction. This tells the other bees the food is
close by; the scent they detect on her alerts them to what the new
food smells like. So the other bees leave the hive and fly around
in ever-widening circles until they find the new supply of flowers.
If the new source of nectar or pollen is quite distant, the scout
makes an ingenious alteration to her dance. She will dance the shape
of a 'figure eight', with intermittent movements across the middle
of the figure. The distance at which the changeover takes place,
from round dance to figure eight, varies between subspecies of bees.
But this does not cause confusion among the bees, for the distance
is constant within each hive.
Wiggles
Every movement by the scout has meaning for the other bees. They
can tell the distance
from the food source by the number of times a dancer circles during
a given interval, and also by her wiggling abdomen. The greater the
distance, the more slowly she wiggles.
The direction of the food is revealed by the direction and angle
the dancing bee cuts
across the diameter of the circle. If she wiggles across the circle
straight up, the watching bees know they will find the food by flying
towards the sun. If she cuts the circle straight down, they know
they have to fly away from the sun. Should the dancing bee cut across
the circle at an angle the other bees know they must fly to the right
or left of the sun at the same angle the dancer moved to the right
or left of an imagined vertical line. This dazzling display of the
honeybee dancers is truly a striking feature of the in" sect
world. When we consider the complicated steps of the dance, and the
detailed information conveyed and understood through it by all the
world's honeybees (von Frisch took 20 years to decipher it), we are
entitled to be scornfully incredulous that this process could ever
evolve. Let's try to imagine the system evolving. A bee discovers
a field in bloom. She returns to her hive and no one else knows where
she filled her honey sac. She can't tell them herself, so the hive
has to wait until individual bees haphazardly chance upon the same
field, or she has to
keep going back and forth hoping someone will follow her. Even worse,
she may not
remember how to get back to the field herself!
Inventive Bee
Now let's suppose that one day an enterprising bee manages to invent
the dance. How
would she communicate to the others what it meant? How would she
ever explain the
geometry involved—that the angle she walks across the diameter
of the circle is equal to
the angle between the sun and the food source? What if the sun goes
down before the other bees understand? How does she explain she has
invented one dance for a food
supply nearby, and another for a supply a long distance away? How
does she tell them
that if she wiggles very slowly it means the field is very distant,
and if she wiggles very fast it means the field is not far? How will
they know that if the dancer walks up the honeycomb they should fly
towards the sun, but if she walks down they must fly in the opposite
direction? Even more important, if this process evolved gradually
over a long time, how would all the bee ancestors have survived while
this system of communication was evolving? If they survived without
this complicated method, why invent a new system that would be almost
impossible to explain?
House-hunting
And the uses for the honeybee dance do not stop there. The dance
of the figure eight is
also used when bees are selecting a new homesite. If a hive grows
too large, the queen may leave with part of the colony to search
for a new home. She leaves behind
one or more special eggs from which a new queen will hatch. The old
queen and her
swarm first congregate somewhere, such as on a branch of a tree.
Worker bees are then
sent to scout around for a suitable new homesite. Any scout who finds
a potential
new site returns to the others and tells them where her favoured
site is by doing the figure eight dance on the surface of the cluster
of bees. Other bees inspect each site and return to the colony to
tell the others what they think of it. The enthusiasm of their dancing
reflects their feelings about the suitability of the site. Finally,
after perhaps several days of house-hunting, one of the sites gains
overwhelming
favour and the swarm moves off to start a new hive there. One researcher
watched
this dance contest for four days, noting directions and distances
of potential sites.
He worked out the site which was rapidly gaining favour, then hurried
off to find it. He
arrived at the new dwelling place before even the bees did!*
Conclusion
Among the wonders of God's creation, the honeybee provides some
startling evidences
for design and purpose by the Creator. The precisely coordinated
language used for the
bee's survival has too many necessary and independent parts for such
a system to have
evolved. We are forced by logic and common sense to conclude that
the whole process
was implanted in bees at the time of their creation. Like the bees,
it did not and could
not evolve.
