The Piltdown Hoax



       In the 1900’s a hoax was created in the village of Piltdown in London, it was called the Piltdown Hoax.  An amateur archaeologist Charles Dawson began digging in Piltdown and in 1908 he unearthed a skull in a gravel pit.  In 1911 he discovers more fossil fragments consisting of teeth, soon after there was a public announcement stating the fossils were possibly that of a human skull.  Dawson sought the help of a geologist from England named Arthur Smith Woodward and a leading anatomist Arthur Keith to foster his research.  Ultimately, Woodward confirmed Dawson’s discovery was that of a human skull and described the jaw as apelike in shape.  Woodward was a leading geologist during this time and due to his reputation the scientific community deemed the discovery as the remains of an early human as valid.  Eventually, the scientific community believed this discovery provided the missing link between humans and apes shedding great notoriety for England.  This is important because during this time there was extreme pressure to produce an English fossil because every other Super Power countries had already discovered fossilized early human bones. 
       Later in 1953 Dawson’s discovery in Piltdown was revealed to be a fake, as the skull was modern in shape and the fossils appeared to be altered.  As a result of the advances in technology, the Piltown fossils were tested for its fluorine content, sparking the beginning of the controversy.  The fluorine test of 1949 revealed the fossils were younger than initially claimed.  Better dating methods made it apparent that the stain on the skull was superficial and a steel knife was used to cut the bone.  Furthermore, scientists utilized new technology such as the microscope, to look at the teeth and they discovered the teeth had been filed down, the teeth had fillings, and had deep scratch marks. The data from the new technology revealed that the jaw bone belonged to an orangutan.  All this evidence pointed to one conclusion, that the Piltdown Man was a fake fossil and a hoax.   
       What partially inspired Dawson’s rash enthusiasm for his discovery was his pride, however there were social and political factors supporting the hoax.  Such pride and external factors help to explain the human factor which was involved in the Piltdown hoax.  It is possible to remove the human factor in scientific research by questioning, verifying the facts, and utilizing credible tools before deciding if data is reliable as these are positive aspects of the scientific process; doing this will help to decrease the amount of errors in the data and outcomes of the research.  I would want to remove the human factor from science as scientific research is an advanced and complex skill.  It requires critical thinking as well as an understanding of the complexity of research design and analysis.  If human factors interfere with the primary study it will decrease both the internal validity and external validity of the research.  The Piltdown Man demonstrates the failures of scientific knowledge as a result of wishful thinking, professional courtesy, and bias.  It is imperative that the new dating technology (of that time) was utilized to measure the data which included microscopes and a series of fluorine testing completed by Kenneth Oakley which revealed the accuracy of the data.    
        The life lesson learned from the Piltdown hoax is that research is judged by trustworthiness and credibility of the results.  Threats to the validity of the research can be minimized by creating a logical argument, proper data collection, use of proper tools of measurement, and controlling bias.  Therefore, it’s imperative a valid research study is one in which there is sufficient evidence to support the claim excluding the human factor.

  1. Hello Trinidad. I think this was overall a great post about the Piltdown Man hoax. Your first paragraph, however, confused me a little bit. You kept referring to the Piltdown man as an "early human." This isn't correct. The scientists believed that this was a possible ancestor to humans, making it an early hominid instead of an early human. But the rest of your post is very informative and well thought-out. I agree with what you said about the human flaws that caused the hoax and the trouble it caused. I especially like how you mentioned the social and political factors that came into play. Although most of the human factors that assisted this hoax came from personal levels, such as pride and a desire to be famous, some of them also came from political levels, such as nationalism and jealousy that Britain had not found early hominid fossils. Thanks for posting!

  2. In general, good description of the background of the hoax. Nolan is technically correct that "hominid" is a better term to use rather than "early human" but there are often used interchangeably. Just recognize that 'early human' doesn't automatically mean this was one of our ancestors, just one of the hominids on our family tree.

    Did you get a chance to review the information in Blackboard on the term "missing link"? Is this really a valid term to apply to Piltdown?

    It is important to understand that the significance of this find was NOT that it was a 'missing link'. The significance of Piltdown (had it been valid) was that it (a) was the first hominid found on English soil and (b) it supported the hypothesis that humans developed large brains early in their evolution, even before bipedalism.

    I agree that pride came into play for the general acceptance of scientists (at least the British ones), but I'm not sure how it applies to Dawson (assuming he was the culprit). How about greed? Ambition?

    Good discussion about the technology that helped to uncover the hoax, but what about the process of science itself? What aspects of science helped reveal the bones to be a fraud? Why were the scientists still analyzing this fossil find 40 years after it was found?

    While the negative aspects of the human factor should be minimized (and the scientific method, when used correctly, works to do this), it is incorrect to assume that all human factors are negative. What about curiosity? Ingenuity? Creativity? Can you even do science without these human characteristics?

    Good conclusion.

    1. Great points Instructor Rodriguez, I do agree human factors such as curiosity, ingenuity, and creativity do have a place in science.
