Piltdown Hoax


The Piltdown hoax was an Archaeological site in England, which was discovered in 1908 by Charles Dawson. The scientific community was shocked at the findings as this was a crucial period for evolution. At the site, a fragment of what appeared to be an ancient human skull was found along with animal fossils.  Perhaps most astonishing find was a jawbone, apparently to the same skull found earlier. The jawbone was surprise because it did not look human, it actually looked more like it belonged to an ape. This remarkable find appeared to fit as the last piece to human evolution puzzle, the “Missing Link”.
The hoax was discovered after Word war two. A new technology, chlorine testing allowed scientist to measure roughly date fossils. When they tested the Piltdown fossils,  the results returned was the fossils were relatively young. It would of made sense, if the remains were millions of years old, however they turned out to be more like hundred thousand. Another evidence on how the findings were a hoax was the fact that the teeth were filed down, the were scratch marks, as if some-one purposely wanted to shape these to a desired shape. Finally the jawbone was tested as well and even more surprisingly it dated back only to less than one hundred years.
Charles Dawson died before the hoax was discovered.  Father Tielhard who was an original member of the findings, was very quiet when the hoax was unraveled.  There were other scientists prior to announcement of the hoax,  who were coming up with mixed results after re-examining the bones. For example in 1913 David Waterson stated that  the skull was of a human and the jaw belonged to an ape. A german anthropologist by the name of Franz Weidenbreich who studied evolution studied the remains and he came to similar conclusion that the skull was perhaps of a fossilized ape and that the jaw appeared to be of an orangutan with filed down teeth.

Scientists are indeed humans, and all humans make mistakes. The faults the come into play for this scenario was simply lack of knowledge. Without the tools and technology they could not have tested the age more accurately. This negatively impacted the scientific process because at the time it formed a falsiable hypothesis which couldn’t be tested wrong. Those who were skeptic, kept silent and choose not to speak out against such prominent figures of the time such as  W.J.  Sollas.
In 1953, Scientists launched full scale analysis of the remains. It included radiological dating methods. Pieces were broken off which could of shown that the jawbone did not belong to the skull. They also removed the pieces that would of shown that the bones did not match directly. Furthermore, evidence showed that the front part of the jaw was broken off which proved to be of an ape and not human like specie.

I think it is possible to remove the “human” factor from science at least to a certain extent. A good example of this would be computers. Large, complex calculation no longer have to be handworked and result in human miscalculation, instead computers accurately calculate a desired data for us. I would like to remove the human factor as much as possible to prevent such incident as the Piltdown hoax from wasting the scientific community’s time.
The moral of the story for me was to be very skeptical when approaching new discoveries from an unverified source.  One can be duped purposely to believe something that is not true and waste precious time. Most importantly, I would limit myself from jumping to conclusions no matter how good the outlook my project to be.

  1. Good synopsis with a couple of clarifications:

    What was the significance of the find? What did it tell us about human evolution that we didn't know before? The concept of the "missing link" is a false one that is a common misconception among the public. In science, even then, it is understand that there is no such thing, just a long line of gradually changing organisms over time.

    Another important discovery when the hoax was revealed was that the jaw was that of an orangutan, not a human. I see you mention this in the second section.

    You talk about negatives that allowed the hoax to persist, but what about the human traits that led to it being perpetrated to begin with? Pride? Ambition? Greed? All of these factors can pollute science if a scientist isn't careful about his/her methods.

    The analysis that uncovered the fraud was "fluorine" analysis, not chlorine. Are there any aspects of the process of science itself that helped to uncover the hoax?

    If you took away the human factor, would you lose any positive human traits that help science progress, such as curiosity, creativity and ingenuity? Could you even do science without those factors?

    Good summary.

  2. I agree that all human make mistakes but I think the question that was asked was what human in us made mistakes. Just like Dawson was full of greed and ambition and how he was after that fame not matter what it took. Even if it meant falsifying the jaw of an orangutan. Also the scientist used the fluorine tests to determine the age of the fossil that was found to be less than 100,000 years old, which of course was a lot younger than they suspected. When we were talking about removing human factor I don't think we can remove it. Human factor would be can we remove greed and ambition in science? I don't think we can because then we would not have the stride to achieve what we are after. Overall good job on your post.
