The Piltdown man was discovered in 1912 in Great Britain. It
was discovered by Charles Dawson, along with Sir Arthur Smith Woodward and a priest
named Pierre Teilhard de Chardin. The Piltdown man was thought to be the oldest
humanoid fossil ever discovered, and based on a jawbone that featured flat
teeth like those of a modern human, but was in the shape of an ape jawbone. It was
heralded as not only the “missing link,” but also as the earliest Englishman. Following
the find, the National History Museum
in London and the Royal Geological Society fell
over themselves in support of the find, and in particular, Sir Arthur Keith, a
leading anatomist and anthropologist in England, felt that the fossils
proved that the Piltdown man validated his theories regarding human evolution. Cranial
fossils found near the jawbone seemed to prove that our ancestors evolved large
brains before they became bipedal (this turned out to be false).
However,
eventually new finds were found in other places on earth that looked much
younger than the Piltdown man, but were much less evolved than the fossils
found by Watson. This inconsistency threw up red flags and scientists began to
question the validity of the Piltdown man fossils. Following WWII, scientist
performed fluorine tests which showed the samples were much younger than
originally thought. They then looked at the teeth and the broken segments of the
jaw, and determined that they had been manually worn down using steel knives
and files. Using carbon dating, they discovered that the jawbone was actually
less than 100 years old. It was discovered to have belonged to a female
orangutan. This forgery ended up setting the scientific community back with
years of time wasted at the sites in Piltdown and nearby Sheffield Park (where
a second Piltdown man was “uncovered” by Dawson), and raised many ethical
questions about the faith we have with geological finds.
The reality is that
scientists are people, and people are inherently flawed. The perpetrator of
this hoax defrauded the scientific community and humanity at large. Some of the
suspects include Dawson (the chief suspect), his colleagues Woodward and Teilhard
de Chardin, and a man named Martin Hinton who worked at the Natural History
Museum under Woodward. Woodward continued to work at the sight for decades
after the death of Dawson
and found nothing more to prove the existence of the Piltdown man, and because
of this, it is unlikely he perpetrated the fraud. Teilhard de Chardin may have
known the fossils were a hoax, but was not at the sight long enough to be a
true suspect. The two most likely suspects then are Dawson and Hinton. Hinton
was said to have resented Woodward and may have created the hoax to discredit
him. Also, following Hinton’s death, stained and filed bones were found in a
trunk in his room that were very similar in style and appearance to the
Piltdown fossils. He certainly had the knowledge and skill to perpetrate the
hoax as the head of the paleontology department at the Natural History Museum. However,
some believe the bones were his attempt at trying to discover how the process
was done so that he could expose the hoax. Dawson is the most likely suspect since he
had the most to gain, and was also the one most involved in the findings (which
mysteriously stopped appearing after his death). Dawson was affected by greed, pride and a
desire to be important and noticed in the scientific community. These desires
may have led to him deceiving the scientific community, and ultimately the
world, so that he would be deemed important. While not necessarily a chief suspect,
Sir Arthur Keith is also guilty of exploiting the find to further his own
agenda. He pushed the idea that the Piltdown man proved his theories of human
evolution, and thus made him even more powerful and distinguished in the community.
The irony is that his greatest legacy is built on a lie. The last culprit is
not a person, but a group. The English community (desperate to find ancient
human ancestors in Britain)
was blinded by nationalistic fervor. Rather than let the find explain itself
through examination and study, they made it fit into their own agenda and
failed to see the hoax for what it was, and were blinded by its potential to
fulfill their own desires.
If anything good came out of the Piltdown
hoax, it showed that the scientific method works. One of the most important
parts of the scientific method is the submission of findings for peer review
and testing and retesting hypothesis. The scientists who performed the fluorine
tests on the fossils performed due diligence and refused to simply accept the
findings as fact. They helped to uncover that something was wrong with the
find. The other scientists who put the fossils (literally) under the microscope
and looked for flaws were able to find the evidence of artificial interference
on the fossils and finally, the scientists who dated the bones and discovered
their true age helped to end the hoax. They all performed admirably, and shed
light on the failings of their predecessors, who simply took the evidence at
face value.
The only way to eliminate the human factors
from science is to increase the number of scientists who can test the theories.
When only one person or select group of people gets to study an artifact or
fossil, then they can put their own agenda first and the “truth” second. In the
case of the Piltdown man, the fossils were kept hidden away from the scientific
public, and nobody could test them and check their validity. By opening up the
fossils to more scrutiny, their true nature was discovered and the hoax was
exposed. Human flaws will always creep into research, as we all have personal
biases and agendas to promote, but by opening our work up to criticism and correction,
we can whittle down the effects of those biases on the value of our work.
In all things, be
they politics, scientific discoveries, or economic proposals, one should always
exercise a healthy combination of cynicism and optimism. Though, this sounds
like an oxymoron (which it basically is), I mean to say that one should never
take something simply at face value. We can hope that something is true, or
that we have discovered something important, or that something will greatly
improve our lives, but we owe it to ourselves and to the community to go in
with a critical mind, and try to find weaknesses and ways to improve the
concept or finding. Ultimately, the failing of the scientific community in England to
truly investigate the Piltdown man and express any doubts publicly led to
decades of waste and forced many to doubt the sincere efforts of the scientific
community at large. If scientific theories are to be taken seriously, we must
be critical and unyielding in our search for fact.
Good summary. The key statement you make is the issue of Piltdown being the earliest "Englishman". There were plenty of other finds in other parts of the world, but up until then, England had not made its own find, which is why this was such a big deal. I don't think this was claimed to be the earliest human, just the earliest English human. Also, be very careful about the issue of the "missing link". There is no such thing. Human evolution has been a continuous process with all early species representing an endless chain of "links". There is not one, there are millions. We ourselves are links between our ancestors and our descendents, so it is a useless term scientifically.
ReplyDeleteGreat coverage on the uncovering of the hoax itself and on the positive aspects of science that let to the hoax being revealed. Very thorough. Very good.
So you would suggest that to reduce the effect of the "human factor" we should add more humans? :-) I agree. Scientific competition is a good thing.
Good final section.
Your summary of the incident was perfect. You did a very thorough job and i can tell you did your research. I really liked your idea that this hoax proves that the scientific method works. Without the scientific method we would have never known that the whole thing was a hoax. I think you could have talked more about the human flaws in the hoax, and not so much about who the suspects were. I completely agree with your idea that major scientific discoveries should be more available to more scientists. If more scientists could have seen the Piltdown bones maybe all that time wouldn't have been wasted with going down a path that was going nowhere.
ReplyDeleteWow, this was very well written. I especially like the part about making science less human by having more scientists. That is an excellent way to look at it, I never thought about that. Also, the point that this hoax proves how well the scientific method works was a strong point in your post. You were very thorough.
ReplyDeleteI too will agree that this was very well written, I specially enjoyed your statement on how we should approach "all things" with a healthy amount of cynicism and optimism. I too voiced the same argument that we owe a duty to our fellow scientist to speak up and voice our opinions rather than stay quiet. Its thru a collective that we've been able to obtain the level of understanding of our ancestry , this would of never of happen had certain individuals stayed quiet or just accepted the prevailing thoughts of the time.
