Piltdown Hoax

The Piltdown hoax occurred in 1912 in Piltdown, England, when amateur archaeologist Charles Dawson was digging in a gravel pit. He then supposedly discovered a piece of ancient human skull. The top of the skull looked like a modern human’s, but the jaw was very similar to an apes. He then invited Arthur Woodward to Piltdown, and since Woodward was a well-established and respected archaeologist, the finding was deemed revolutionary to the theory of human evolution. The people of England were enthusiastic and thrilled that their country too had ancient human fossils. It supported the idea that many scientists believed that human evolution began with the brain, and upright walking came later. We now know this is incorrect, as upright walking came first, then the larger brain. For forty years the hoax went undiscovered and scientists went on following this model of human evolution. However, new skulls were then being found in Asia and Africa which appeared to look more like apes, and less like humans. These fossils were much older than the Piltdown findings, and this conflicted greatly with the timeline of human evolution. Then, scientists began testing the fluorine content of fossils to calculate their age. It was learned that the fossils Dawson found were not more than 100,000 years old. Additionally, closer analysis showed intentional staining of the fossils and filing down of the teeth to make them look more human. The hoax setback our understanding of human evolution, but it also taught scientists to test evidence more thoroughly.
            Many human faults came into play with the Piltdown hoax. The biggest issue was the egos involved in the fake discovery. Regardless of who committed the falsification, one of the men involved let their pride takeover and wanted to achieve success without having to work for it. He wanted to receive notoriety for his discovery so he could feel important in his field. Furthermore, nationality and patriotism comes into play, since many people of England believed this information at face value simply because they wanted their country to have ancient human fossils like Asia, Africa, and other European countries. Furthermore, at the time, these Piltdown fossils were thought to be the oldest yet, once again inflating the pride of English scientists.
            By measuring the fluorine content of the fossils, scientists were able to determine the approximate age of the ancient skulls. They could also see that a steel knife was used to cut the remains, along with artificial staining. When they examined the remains under a microscope, they could see scratch marks on the teeth, indicating the teeth had been filed down.
            I do not think it is possible to remove the human factor from science. We can take as many steps as possible to reduce its presence in science, but it can never be wholly eliminated. We are human beings with flaws and emotions, and we can never be completely objective. However, I do not always think this is a bad thing because it can lead to improvements in evidence testing (as it did with the Piltdown hoax), and it leads to new innovations and opinions every day in science.

            In all aspects of life, but especially when it comes to scientific information, I think it is extremely important to research and test evidence in order to verify its validity. If we simply accept what is told to us without questioning it, then we will miss out on the truth of many situations. We need to question and doubt in order to learn new ideas.

  1. Hi Halle,
    I really enjoyed reading this post. I thought that you gave a great balance of information and personal opinion. I liked that you included the tidbit of scientists thinking that the larger brain came first before upright walking and later finding out that, that's not true. I did not even think of attaching patriotism with the human faults involved with this hoax but it is definitely fitting. Good job!

  2. Hi Halle,
    I think you did an awesome job with this post! You have great analysis and even though I knew most of the facts from my own posting, I felt like I learned more from reading yours. You brought up a couple points I had not thought of. You did not write too much or too little, either. Great Job!

  3. Great job with all of the detail and structure of your post. Reading your post actually reinforced my understanding of the Piltdown Hoax. Verification for validation is a process I strongly agree with.

  4. Excellent synopsis. Precise and factual. Well done.

    Good discussion on the faults involved, covering both those providing the motivation for the culprits who created the hoax and those which led scientists to accept the find too quickly.

    Good description on the technology used to provide evidence for the hoax. Besides new technology, what about the process of science itself helped to uncover the hoax? Why were scientists still analyzing this fossil some 40 years after it's discovery?

    While I see your point on the good that can come out of human error, are there only negative aspects to the human factor? Are there no positive aspects that you would not want to lose, such as curiosity, ingenuity and intuition? Could you even do science without these things?

    Good life lesson.
