Piltdown Man

     In 1912, a small town in Lewes, England called Piltdown was home to the discovery of a fossilized piece of an ancient human skull. The find was credited to an amateur archaeologist named Charles Dawson. The reason why this fossil was highly regarded was due to the fact that it could have been the missing evolutionary link between humans and apes. After the discovery, Dawson convened with Arthur Keith, Sir David Woodward, and Telihard De Chardin in order to present the fossil to the scientific community at large. Widespread groupthink occurred amongst the scientists throughout England and perhaps even the world. No one doubted the findings since Dawson's group then went on to find several other fossil pieces to supplement his initial discoveries. As well as the fact that fossil dating technologies were essentially non-existent during that time period. However, discoveries of ancient human fossils surfaced in Asia and in Africa. These fossils were much older and were inconsistent with the composition of Piltdown Man. This led to widespread skepticism of Piltdown's legitimacy and in 1949 a fluorine test was conducted and determined that the fossil was no more than 100,000 years old. Further thorough testing revealed that the fossils were: artificially stained, cuts were made throughout the fossils with a steel knife, and that the teeth belonged to a orangutan which later revealed that the fossil was less than 100 years old. The overwhelming amount of evidenced led to the conclusion that the Piltdown Man was nothing but a mere product of clever forgery. 

     The scientific process was clouded in this case due to national pride, hubris, and groupthink. Dawson was an ambitious man, he wanted nothing more than prestige within the scientific community. Apart from the Piltdown fossil, it was also discovered that many of his archealogical findings were also products of forgery. Scientists are humans too, which means that they are not immune to the forces of desire and greed. Another fact to consider is how the scientific community did not have any skeptics (perhaps Hinten was), and their decision to accept the fossil as true evolutionary evidence was due to the overwhelming amount of national pride and general jubilance everyone at the time incurred. England wanted to prove that they were also scientific pioneers and did not want to fall behind other European countries like France. 
     
     Where there is darkness, there is light. That light definitely shined when the skepticism of the Piltdown fossil grew. Advances in scientific technology like the fluorine dating test was developed and resulted in the exponential growth of said skepticism. Chemical tests and technologically advanced microscopes showed that a lot of what made the Piltdown fossil "authentic" were artificial. The utilization of the scientific method in order to answer the question "Is this truly a connection between humans and apes?" was used and further research and testing led to the conclusion that Piltdown man is simply a hoax.

     Scientists are the backbone of the entire subject of science. Without scientists, our understanding of science would not be as comprehensive as it is today. The fact that scientists are human means that is nearly impossible to remove the human factor out of science. However, as we advance technologically, so do our means of authenticating the discoveries made in the field of science. Countermeasures are in place in order to combat the human factor and the enforcement of the scientific method as well as peer-reviews are well implemented. Although it would be great to have an autonomous way to procure scientific data, I feel that the human factor is simply something that can not be removed.

     The life lesson here is, always be skeptical. Keep an open mind but do not be impressionable. It should take more than mere words and shoddy evidence to influence one's mind. Never succumb to hubris and groupthink, always think outside the box.

  1. This is a thoroughly wrote blog post. However, you should elaborate more on what we should be skeptical of.

  2. "The reason why this fossil was highly regarded was due to the fact that it could have been the missing evolutionary link between humans and apes."

    No, and it was specifically stated in the guidelines that the term "missing link" was not to be used in this post as it is misleading term. Make sure to go back to the background information to review the problems with this concept.

    By this time, it wasn't really an issue as to whether humans and non-human apes (see how I phrased that?) were related. It wasn't about "if" they were genetically related, but how humans had evolved from that common ancestor with non-human apes. So what would this discovery have taught us about "how" humans evolved? Why was the size of the Piltdown cranium relative to the comparatively "primitive" nature of the Piltdown jaw? Check out Arthur Keith's pet theory of the evolution of larger human brains.

    Another key piece of significance is the fact that this was the first fossil hominid found on English soil.

    "No one doubted the findings..."

    Actually, some did but were ignored.

    I appreciate that you noted that science was continuing, producing additional fossils that contradicted Piltdown's conclusions. This was an important driving force in re-examining Piltdown, ultimately leading to evidence of the hoax.

    Very good discussion on human faults, including both the faults of the perpetrators and the scientific community. Note that we still aren't sure if Dawson was behind this hoax or not.

    Great discussion of the positive aspects of science that eventually led to the uncovering of this hoax, both the technology and the methodology.

    While I understand your point in your section of the "human factor", you seem to be assuming all factors are negative. Is that the case? Do humans bring nothing positive to the scientific process that you would NOT want to lose? How about curiosity, ingenuity and innovation? Could we even do science without these factors?

    Good life lesson.

  3. Hi christian,
    I think you did a great job explaining the situation. Your use of detail is nicely put together and your responses are giving points that I can easily understand and agree with. Nice job.
