On the trail of chickens, eggs and ducks
A recent report in The Times brought to mind a variation of the old “which came first, the chicken or the egg” question. Now we must ask “where first” as well.
Archaeologists in South America found some ancient chicken bones which,
on analysis, proved to be genetically identical to others found on similar
digs in Asia. I think we can assume the birds did not fly across the
Pacific Ocean.
Most experts believe the Pacific was peopled from the east as the great
Polynesian navigators moved from one island group to another until reaching
a limit defined by an arc from Hawaii, through Easter Island to New Zealand.
Did they also take chickens to Peru?
Sixty years ago, in the summer of 1947, a battered bundle of balsa wood
logs crashed onto a coral reef. Kon-Tiki had arrived even though experts
had predicted the balsa logs would quickly become waterlogged and the
bindings disintegrate in salt water. However, Thor Heyerdahl and his
crew sailed the raft about 4,300 miles from Callao in Peru to the tiny
atoll of Raroia in Polynesia.
Heyerdahl knew that similar balsa craft had traded along the coast and
out as far as the Galapagos Islands. He also knew the legends about a
defeated king, Kon-Tiki, who sailed westwards away from Peru following
the sun. He thought the prevailing currents and winds could favour westward
travel and had recorded stories in Polynesia about a tall, white, bearded
leader they called Tiki who came from the east. Did he bring the chickens?
Of course, showing a journey was possible does not mean it happened,
but it does seem to demonstrate that the oceans are highways rather than
barriers to exploration. Further proof comes in the shape of 29,000 yellow
plastic ducks (with some blue turtles and green frogs) lost from a container
ship during a storm in the eastern Pacific in 1992.
So far they have
been found on beaches in Australia, South America and Hawaii. Some drifted
up into the Bering Sea, were frozen into the Arctic pack ice then escaped
into the Atlantic Ocean. After drifting 17,000 miles the wind and currents
will bring them to the beaches of the south-west of England, probably
Cornwall, later this summer.
Beachcombers should look out for yellow ducks stamped with “The
First Years” for proof of the way our ocean environments
interconnect.
