The dodo once
waddled along the deserted beaches of Mauritius blissfully unaware than when man
arrived in the sixteenth century he would shake the harmony of its existence.
The Dodo was first sighted
around 1600 on Mauritius and it was extinct less than eighty years later.
The skeleton as shown below is on view in the Museum and is real.
The model
of the Dodo as shown below is not real, as there are no complete
Dodo specimens. Some of the birds may have been eaten by the Dutch sailors who
discovered them. However, the primary causes of their extinction were the
destruction of the forest (which cut off the Dodo's food supply), and the
animals that the sailors brought with them, including cats, rats, and pigs,
which destroyed the Dodo nests.
The Dodo's stubby wings and
heavy, ungainly body tell us that the bird was flightless. Moreover, its
breastbone is too small to support the huge pectoral muscles a bird this size
would need to fly. Yet scientists believe that the Dodo evolved from a bird
capable of flight into a flightless one. When an ancestor of the Dodo landed on
Mauritius, it found a habitat with plenty of food and no predators. It therefore
did not need to fly, and, as flying takes a great deal of energy, it was more
efficient for the bird to remain on the ground. Eventually, the flightless Dodo
evolved.
Scientists
at the American Museum of Natural History and other institutions around the
world continue to study and document the impact of human activities on the
environment. It is hoped that the lesson of the Dodo can help prevent similar
extinctions, and aid us in preserving the diversity of life on earth.
Myth
of the fat Dodo
The bird's obesity, slowness and
lack of intelligence are commonly given as reasons for its alleged evolutionary
inferiority. Dodos were for years considered not just large, but grossly
overweight to the point that they not only couldn't fly, but could hardly run
from their enemies. Kitchener, though, in studying the written record, found
that the earliest dodo drawings showed rather thin birds, only those drawn later
show the familiar podgy variety. He found that thin dodos were drawn
by those who had actually visited Mauritius, the plumper birds were drawn mostly
by artists in Europe. More than a dozen original pictures (both drawings and
paintings) of the dodo now exist. Kitchener next evaluated the hundreds of dodo
bones that have been unearthed. Using methods developed by criminologists and
archaeologists to reconstruct flesh on bones, he was able to determine that the
skeletal pattern produced a bird 'remarkably similar to the first drawing of the
dodo'. namely the thinner birds. He concluded that 'according to four
different methods, all based on the dodo's bones, the famous flightless pigeon
weighed between 10.6 and 17.5 kilograms'. Evaluation of the cantilever
strength of leg bones produces a relationship which can be used to determine the
running abilities of different sized animals. This method revealed good evidence
for the conclusion that they were indeed 'swift of foot', a conclusion which
corresponds with eyewitness accounts which stated that the dodo 'could run very
fast'. While this analysis is not without problems, it has produced
eminently reasonable conclusions, especially since the opposite thesis has
little empirical evidence in its favour. Since Kitchener's first evaluation,
original unpublished dodo drawings completed between 1601 and 1602 were
rediscovered in a museum in The Hague, the Netherlands. These showed that
Kitchener's conclusions were correct, the dodo was thinner and the femur design
was tilted downwards, reducing the bending forces on it and allowing it to shift
its centre of gravity. This evidence demonstrates that the dodo was an
effective, fast runner. Kitchener concludes, 'for more than 350 years the dodo
has been thoroughly misrepresented as plump and immobile. The reality is,
however, that in the forests of Mauritius it was lithe and active. Like other
Mauritian birds it would have undergone a seasonal fat cycle to overcome
shortages of food, but never to the extent that those wonderful oil paintings
suggest.'
The last survivors
Since the birds
were easy to capture, Dutch colonists, along with sailors and visitors, soon
consumed most of the dodo population. Animals they brought with them, especially
dogs, cats, and pigs, ate the fledglings and broke the dodo eggs to consume the
yolks. By 1681, the dodos were all gone. Rather than demonstrate the weakness of
the dodo, their history effectively demonstrates the gross irresponsibility of
their caretakers. According to Panati, 'not a single naturalist had attempted to
mate any of the captive dodos; they left no descendants.' The last dodo in
England was stuffed by English naturalist John Tradescant. When Tradescant died
in 1662, his entire natural history collection was bequeathed to an
acquaintance, Elias Ashmole. Because of his irresponsibility, the entire
collection's condition greatly deteriorated, and he donated the bird to Oxford
University in 1683, two years after the last living dodo was seen on Mauritius.
Even Oxford did not take very good care of the bird, and except for the head and
foot saved by a farsighted curator, it was later burned as trash in 1755.
Evidently 'the museum's board of directors took one look at the dusty,
stupid-looking bird and unanimously voted to discard it'. The intrigue
over the bird was such that by 1800 'professional naturalists were casting doubt
on written descriptions of the bird, as well as on extant drawings . . . it
became scientific vogue to deny the bird's existence and to challenge the Oxford
head and foot as fakes'.] If it was a genuine bird, the critics reasoned,
certainly there would have been extensive efforts to preserve it or at least a
good skeleton.
Search for evidence
A group of zoologists searched
in 1850 for evidence, to the extent of travelling to Mauritius looking for bones
and found none. Soon the dodo was denounced as a scientific fraud. Evidence did
not surface until a resident of Mauritius, George Clark, searched the island and
in time discovered numerous scattered bones. His specimens were soon shipped to
major museums, and after study were pronounced authentic. These researchers
later attempted to assemble the bone fragments, many in poor condition, into
complete dodo skeletons. They are now regarded as real animals, but the many
other myths surrounding them have died slowly. These myths were widely believed
because they seemed to support the idea of evolutionary naturalism.
Now that the bird has been extensively studied, we realise that the facts do not
support the evolutionary myth, but do support the moral bankruptcy of
humankind.
