Piltdown man

The Piltdown Hoax was an archaeological find that was located near Piltdown village in Sussex, England. This discovery was found in Pleistocene gravel beds by a laborer who later gave it to an archaeologist named Charles Dawson in 1912. This fossil would have provided us with a new branch of the evolutionary tree and might have given us a view of an early common ancestor or a species that branched off from the evolutionary tree. The fossil would have provided us with mankind's earliest ancestor and a connection between humans and apes. This discovery proved that Darwin’s Theory of Evolution was right. This also gave scientists the idea that our earliest ancestors weren’t actually from Africa but from England. Even though it was considered a crown jewel within the Natural History Museum, many people still had their doubts still. The hoax was uncovered within the museum by a man named Kenneth Oakley, who used a chemical test in order to help authenticate and date the fossil but to his surprise, the Piltdown man was younger than expected. Then a separate test was taken place within the mineral department to estimate the nitrogen content and they found that the fossil wasn’t as old, the skull was stained, and the teeth were filed down. After the hoax, many scientists who built their careers upon this discovery lost their credibility as scientists and this was also embarrassing for the British sciences.

The fault within this hoax has to be greed and the desire to become famous. Charles Dawson created this hoax in order to get his name out there within the scientific community in Britain and gain recognition and credibility as an archaeologist. He was considered one of the foremost amateur antiquarians during his time. This allowed him to present things to the Royal Society, Antiquarian Society, and British Museum directly. These presentations gave him credibility as an archaeologist and a scientist. I think that this negatively impacted the scientific process because without even analyzing the skull or doing research to date it, people believed that this was our earliest common ancestor without proof but the testimony of several people.

The positives of the scientific process that proved this to be a fraud were observations as well as experimentation. Without the chemical test, the age of the skull wouldn’t have been reached.  Without the microscope, scientists wouldn’t have been able to see the grind marks on the teeth.

I think that it is possible to take out the human factor within science so that something like this doesn’t happen again because we are able to make mistakes as well as skew data but with machinery, we can have precise and true date. I personally wouldn’t take away the human factor because without our intuition and creativeness we wouldn’t be living the way we are in society and constantly making new breakthroughs in technology.

I learned that you should never take the words of others as factual until you researched and determined if what they are saying is either true or false. Even though what they are saying might be true it is always important to do extra research and come to a conclusion by yourself.

  1. It would have been good to provide a few more details in your synopsis for your reader. This is a complex story and a clearer picture would have helped. Who else was involved besides Dawson? What was the response of the scientific community? How many years did it take to uncover the hoax?

    You've offered several possible options of significance:

    "The fossil would have provided us with mankind's earliest ancestor and a connection between humans and apes. "

    No, the "connection" comment is just another way of saying "missing link". It isn't just the words that are the problem but the meaning behind them which fails to reflect how evolution actually works. The assignment module provides background information that explains the problem with this concept. Make sure you take the time to review this.

    "This discovery proved that Darwin’s Theory of Evolution was right. "

    No. By this time, Darwin's theory wasn't in question, and neither was the fact that humans and non-human apes and other primates 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? Piltdown was characterized by large cranium combined with other more primitive, non-human traits, suggesting that the larger brains evolved relatively early in hominid evolutionary process. We now know this to be incorrect, that bipedalism evolved much earlier with larger brains evolving later, but Piltdown suggested that the "larger brains" theory, supported by Arthur Keith (one of the Piltdown scientists) was accurate.

    "This also gave scientists the idea that our earliest ancestors weren’t actually from Africa but from England."

    No, they didn't go this far, just that England could claim a hominid in the hominid family tree.

    I agree greed and ambition likely played a role in why the hoax was perpetrated in the first place, but keep in mind we still don't know for sure that Dawson was actually a culprit or a dupe. Other than the culprits, can you find fault with anyone else? How about the scientific community? Why did they accept this find so readily without proper scrutiny? What might have inspired them (particularly the British scientists) to not do their jobs properly when it came to this particular fossil?

    Good discussion of the technology used to uncover the hoax, but what made scientists come back and retest Piltdown? What was happening in paleoanthropology in those 40 years that pushed them to re-examine this find? What aspect of science does that represent?

    I agree with your conclusion in the 'human factor' section, but I do challenge you to re-think the idea that we could actually remove the human factor from science. Could we even do science without the positive aspects of human nature that drive the process?

    Good life lesson.

  2. Hello Brian, I agree that if it wasn't for the fluorine testing maybe today people would of still assume that the Piltdown man findings was true, it definitely taught science a lesson and even myself on how one must not always take peoples word for it; regardless of their title. One must always questioned and find answers.

  3. Hello Brian,
    I enjoyed reading your comment about our similarities in our post and I'm glad we found common ground with our point that with mistakes we get to further our knowledge. Also I agree with your point that "the way we are in society and constantly making new breakthroughs in technology." because of that we have tons of new technology and findings !
    Great Post and very informative as well.

  4. Hi Brian,

    I agree with you that the human factor could be taken out of science, however I disagree with you that it shouldn't be taken out. When I think of the human factor I think of things like greed, trusting without evidence, and not scientific technology that led to knew discoveries. To me, that is not a human factor, that is a scientific factor. I wish you had elaborated on your opinion on the matter more. I didn't feel like you provided us with much of a reason to back up your response. Especially because I differed in opinion, I'm curious to hear more on why you wouldn't take away the human factor in science and why you feel we wouldn't be living the same way we do today.
