The Piltdown Files: Science vs. Dawson
In Southeast England, in a rural town called Sussex was an amazing discovery in the early 1900s. A laborer was digging near the village of Piltdown at the Barkham Manor and unearthed what was going to be known as a great scientific and historical discovery. The remains of a fossilized skull was given to an amateur archeologist by the name of Charles Dawson.
**editors note: the video states that Dawson was digging and found the remains but in the transcript of the video from the assignment's provided link, the narrator states that it was uncovered by a laborer and handed over to Dawson**
Dawson claimed that with closer examination of the skull that it was thicker than that of a human and appeared to be primitive. This discovery became an important one as Charles Darwin's theory of evolution had recently been publish just 50 years before. After the publication Charles Darwin's Origin Of Species the first remains of primitive man were discovered in Germany and was named "Neanderthal". Soon after Germany became the birthplace, discoveries were made in France and Spain but no British discoveries were made until the discovery in Piltdown.
Dawson enlisted the help of a geologist, Sir Arthur Woodward of London's Natural History Museum. An apelike jawbone with humanlike teeth was discovered while he accompanied Dawson in digging at the site. There was still some speculation of it's origin due to a missing piece which would connect the jawbone to the skull and a canine that would help determine if this fossil was more human or apelike. A year later, the missing canine was uncovered and then in 1917 another skull and tooth of a second Piltdown Man.
For over forty years this was an extraordinary breakthrough because until the discovery of the Piltdown Man little was know of man's early ancestors. Scientists were able to observe and build their careers around this miraculous find. But after twenty years more remains of early man have been discovered in other parts of the world and was shown to be much more apelike that Piltdown Man, but was dated to be more recent. Then in 1953, it was discovered to all be a hoax. Dawson was dubbed a phony and the credibility and careers of all scientists who built their work upon the Piltdown Man was at stake. With the scientific community in an uproar and the reputation of London's Natural History Museum at stake, the museum ran more tests that confirmed the allegations. It was a fake. The humanlike teeth were obviously filed down to appear more human like, the jawbone actually belonged to an orangutan and the skull was not as old as it appeared. The pieces were all filed and stained to appear to be the fossils of man's early evolution. Till this day there have been many suspects as to who was an accomplice in this crime and the mystery still remains.
Science is an amazing field. It helps us understand the world around us. There are many great scientist that have made valuable contributions to how we understand our world. These men such as Galileo, Copernicus and Einstein will be always be remembered and valued for their work and discoveries. But not all scientist will make major break through discoveries. Some will never be listed in our history books, and for some that may be very frustrating. People generally want to be recognized for their work and efforts. No one wants to be stuck in a job where they feel unvalued but others take it a step further. People such as Charles Dawson crave the praise and fame so much that they are willing to risk the credibility of their respective fields and others who work hard to maintain their integrity. Such selfish acts also set real science back because what scientists know to be true isn't and all of their work was in vain and must start again with a clean slate at no fault of their own.
Testing of authenticity and hypotheses are vital in science. Everything must be tested thoroughly several times and looked at from an objective perspective. In 1949 with new technology scientists were able to more accurately date the fossils using fluorine tests. These tests confirmed the speculation of the falsehood of Piltdown Man. More tests were conducted and the fossils were more closely examined under a microscope revealing the filing of the teeth and the orangutan origins of the jawbone making the entire discovery a sham.
Although human error or sometimes lack of integrity can cause an enormous setback in scientific studies I don't think it is possible to take the human factor out of science. Without the human factor we wont be able to look at things from different angles. Computers and machinery do not have a curiosity about the way things work. The human factor is essential in the scientific method. It causes curiosities that lead to hypotheses. If an experiment or study is done correctly and for it to be sound science, all hypotheses and discoveries will be questioned by other scientists which is also part of the human factor which then should lead to vigorous testing to solidify or disprove the claims.
It is very important in science and in life that as much as we want something to be true, regardless of how great it may seem, we must always approach it with at least a bit if skepticism before leaping in full heartedly. And if that thing does seem to be a bit sketchy we should never be afraid to speak up and vocalized our concerns. Things should always be tested before for taken for face value because the human factor is in everyone's DNA and sometimes we even lead ourselves astray so we can't expect less from anyone else.

Very well written. Nice images as well, it made it more interesting to read. I thought this hoax was very interesting. We had the same answers and ideas. I think that we need human remains in order to learn more about science and evolution because humans are so special and have many things other species don't. I also agree that things must be tested before making assumptions, we dont want to give out false hope. We also need everything t actually think before doing something.
ReplyDeleteScience is an amazing field. It helps us understand the world around us.
I love this sentence, it is so true. Science helps us learn and grow and that's why this hoax helped us even though it was a fraud, we get the chance to grow from in to earn more about evolution.
Very good synopsis with just one key piece of information missing. Other than being the first find of early man on British soil, why would this fossil have been important for the study of evolution, had it been valid? What would it have taught us about how humans evolved (and why was Arthur Keith such a big supporter)? You hint at this when you talk about how subsequent finds didn't seem to match the information provided by Piltdown, which led to further examination to understand these contradictions. You provided a lot of good information. You just needed to finish the story!
ReplyDeleteI agree with the faults you assign to Dawson (or whomever might have been the original culprit), but what about the scientific community itself? What faults led it to accept this find so readily without the appropriate level of review and skepticism? Why didn't they do their jobs as scientists?
Good discussion on the technology that was used to uncover the hoax.
Other than better technology, what about the scientific method itself helped to uncover the hoax? Why were scientists still investigating this find some 40 years after it was uncovered?
"It causes curiosities that lead to hypotheses"
:-) That is precisely correct. Could we even do science without humans?
Good life lesson.
Very nice read, I enjoyed it. I think, though, that technological limitations were only responsible for so much in this case. The microscope, for instance, had been around for many years. The optical microscope was used as early as 1860 and could provide a magnification of up to 1500x. That's definitely enough to make out filing marks on a tooth. Drilling into the bones revealed that the coloration was only superficial...they could have compared that to other fossils from the same era.
ReplyDeleteI believe that, regardless of who perpetrated the actual forgery, the English scientific community WANTED it to be real. If anything they bear just as much responsibility for enabling the fraud as the person who built the bones. They didn't want to risk it being a fake and it took a generation for that sentiment to be overcome.
I enjoyed your post. Your essay was very thorough in summarizing the Piltdown hoax. I did missed the editors notes regarding a laborer discovering the skull fragments and handing it over to Dawson. I agree that testing the authenticity and hypotheses are vital in science and that humans are a factor because of curiosity. As your life lesson describes we should be skeptical, this in some ways are the same as scientist hypothesizing. It helps us learn and improve science. Nice post!
