Piltdown Hoax

                The Piltdown hoax was the discovery of fossils that resembled both human and ape bones. This was believed to be evidence that humans evolved from apes. A jawbone found resembled that of a primate, but the teeth still fully intact in the jawbone was like human teeth. This discovery was made by three men, archeologist Charles Dawson, paleontologist Arthur Smith Woodward, and paleontologist Father Pierre Teilhard de Chardin. They made their discovery in a town called Piltdown, in England in 1912. This was a proud discovery for England, as primitive human remains were found in France, Germany, and in Asia, but not England. This discovery not only included England in this group, it also gave them the oldest found primitive human fossil. Since this find was of such great importance the fossils were kept under lock and key preventing scientist from examining the remains. Those that might have been skeptical did not vocalize their ideas because of Woodward’s high reputation which was associated with this find. In 1920 more remains were found in Asia and Africa with younger remains of human ancestors, but these remains had more ape like features than that of the Piltdown Man. This raised suspicions that the Piltdown man might not actually be real.
                A scientist is first and foremost a human, with human traits, and human qualities. Just like every other human, they can fall victim to a lie. The brain’s first reaction to learning new information is to accept it as true, then it goes through its knowledge relating to the topic presented, deciding if in fact it is true. If there is a doubt or if there are emotional ties, a human can be swayed to a side without verifying. This is what happened to the scientist of the Piltdown Hoax. England, not finding any remains of early humans, was discouraged and jealous of the other countries that had such discoveries. The moment Dawson announced his discovery England was elated so much so, they didn’t take the time to verify if the facts were true. At this time, scientist were gentlemen and scholars meaning they were trust worthy and out to discover the truth, not make lies. The idea of a scientist creating a scientific hoax was just not plausible to people at that time. Their innocent naïve nature as well as the hope for this to be true obscured the scientific process that should have been at the forefront of this discovery.
Even though the scientist of 1912 got caught up in the hoax of a man evolving from an ape, it was science that was able to call this a hoax. In the early 1900s there was not a valid system in place to properly date fossils. However, by 1953 there was great improvement on this front as well as many other improvements for fossil discoveries. Scientists were finally able to conduct a full scale analysis of the actual jaw bone discovered by Dawson at the Piltdown site. Fluorine analysis was done which dated the jaw to be only 100 thousand years old, not a million years as was claimed by Dawson. They further investigated and found that the staining on the bone was artificial. In fact, what was discovered was the jawbone belonged to a 100 year old female orangutan. This jawbone was already fossilized when it was cut by a steal knife to fit the appearance of a human ape hybrid. Any and all ape like traits where either broken off or cut off by the steal knife making it difficult at first glance to tell it was the jawbone of an orangutan. They discovered scratches on the teeth which showed that the teeth were actually filed down to look like early primitive human teeth. This filing was done on the cusps and the canine tooth. 
                It is absolutely impossible to remove the human aspect from science. It is like asking if humans could be removed from scientist. This is not possible as they are one in the same. Until science can create artificial life to do the jobs of scientist, human and science will always be a pair. Even if it is possible to create an artificial scientist either by robotic mean, or by de-humanizing a scientist, I do not think it is a good idea. I think that mishaps like the Piltdown hoax will happen with human scientists, but I believe that this is all a part of life, growing, learning, and developing. There will always be unforeseen obstacles in the way and hindsight is always 20/20, but there will be a learning curve and valuable lessons will be learned from each hurdle.
                The life lesson learned here by scientist is not to be so naïve and trusting of people’s word, no matter how enticing it sounds. Keep a skeptical mind, ask question, and evaluate the proof first hand. If the facts are not made available, then this should be a warning sign that this could be a hoax. Dawson did a great job with this con, by filling this void England had for not having primitive human fossils. Whether Dawson acted alone, or if he had brought in help from Martin Hinton, or Arthur Keith, or Father Pierre Teilhard de Chardin, or even Arthur Smith Woodward, he accomplished his goal. The likely hood that Woodward was in on the hoax is highly unlikely as he kept on digging after Dawson’s death hoping to find more fossils, but he never did find any more. Dawson was using Woodward for his reputation to solidify his hoax. Having a priest as a party to your discovery adds trust worthiness. When the discovery of Piltdown man was a hoax the Father was quiet on the subject, not sure if he was in on the scam or if he was embarrassed to be fooled by Dawson. Arthur Keith was a leading anatomist who had the most to gain from this discovery as it validated his theory on human evolution. Martin Hinton became a zoologist and discoveries of similar cute bones were stained in the same fashion as the Piltdown man was found on the trunk of his old car. All signs point to a con-artist, but now scientist know to not take truth on a bias whim, or by someone claiming it to be true.

  1. Careful of your terminology. Humans are both apes and primates, so when you say that "both human and ape" bones were found, it doesn't really give any distinction between the two sets of bones. Neither does saying that something "resembled a primate"... so does it resemble a human, since humans are primates? :-) Did you perhaps mean that "both human and non-human ape bones were found" and that the jaw "resembled a non-human primate" or even an "archaic primate"? Words are very important in science. Make sure you say exactly what you mean so you don't create misconceptions in with your readers.

    Also, by this time it was general understood that humans had evolved from a common ancestor with modern apes (notice how I rephrased that from just "ape"?). It wasn't a question of "if" we evolved from that common ancestor but "how". So what would this fossil find, had it been valid, have taught us about how humans evolved? That is the significance. Aside from the archaic jaw, what did the skull look like? Did it suggest a large or small brain? Why is this important?

    Great discussion on the issue of human faults, though I wouldn't let the scientific community off so easy with the "gentlemen and scholars" explanation. Science isn't about trust. It is about verifying information, not just once but repeatedly. I suggest they were swept up by the idea that England might have their first fossil hominid ... finally. But no excuse. They should have given it more scrutiny, though there are suggestions that the fossil wasn't as readily available for testing as it should have been.

    Good description of the tests and technology used to uncover this hoax. What about the process of science itself? What aspects of the scientific method helped to uncover the hoax? Why were scientists still testing this find some 40 years after it was discovered?

    Very good discussion on the issue of the human factor.

    "It is like asking if humans could be removed from scientist."

    Well stated.

    Good life lesson.

  2. Wow! I didn't even consider how important the correct terminology is! I was just thinking it made sense in my mind, and I didn't stop to consider what my words were actually portraying! It makes sense at why it is so important to use the correct terms when describing to species so closely related. Using vague or broad terms can leave my reader very confused or unsure of my point. Originally I was using "hominid" for early humans, however, I think that still might be to vague?

    The skull size was two thirds the size of modern human. This means that human evolution began with the brain. This is why Arthur Keith was so excited about this discovery because it supported his theory that the human brain evolved first, by becoming larger, then humans evolved to bipedalism.

    I agree about not being so trusting and to verify the information before stating it as a fact. If every scientist was trusted that easily, I shutter to thing where would we be scientifically. Would we be watering the plants with Gatorade like the movie "Idiocracy"?

    The scientific method was used to uncover this as a hoax by other discoveries in Asia and Africa that displayed younger humans with more archaic primate features. Since Dawson's Piltdown man seemed like the exception to the rule, scientist hypothesized that Piltdown was a hoax. Through their research they were able to prove their theory as true. This took so long because in order for scientists to see this for a hoax, other discoveries had to be made to point out that the Piltdown man was inconsistent with the all other findings.

    1. Good follow-up. Actually, hominid would have been perfect as it distinguished between the "in-group" that we are focusing on to the "out-group" (all other primates including non-human apes) that we are comparing them to. It is the most direct term that offers the distinction we are looking for.

      The skull was 2/3's the size of a human brain but more importantly, it was more closely sized to the modern human brain than other finds so far and significantly larger than a chimpanzees, which is often substituted as an equivalent to the brain of that common ancestor between modern humans and modern apes. That large hominid brain with a non-hominid jaw suggested that the brain evolved first.
