1. In 1908 a worker in the English town of Piltdown allegedly presented a skull fragment to Charles Dawson. In 1912, four years after the initial find, Dawson told the Geological Society of London that the skull was very similar to that of modern day humans. He believed that the skull belonged to a so called "missing link", our ancient ancestor that allegedly connected apes and humans. If the findings were accurate the Piltdown man would have shown that our brains developed faster than our omnivorous diet, which would be a significant finding if it were accurate.
Because the Piltdown man was the believed "missing link", other remains found in other parts of the world were mostly ignored. These remains would have pointed scientists in the right direction about our earliest ancestors, instead they were sidetracked on how to discover how the Piltdown man fits into what was known. Over time the validity of the Piltdown man was eventually questioned.
In the decades after the finding there became better methods to more accurately date remains and fossils. One of these methods was the fluorine absorption test, which would eventually discover the truth about the Piltdown man. It was found that the part of the bone fragments was actually a jaw from an orangutan that was combined with a piece of skull from a modern day man. Teeth that were discovered were also found to be filed down. Dawson died before the hoax was revealed so it is unlikely that we will know that Dawson was behind the hoax. Arthur Woodward, who worked at the British Museum, assisted Dawson in his findings. It is believed that Woodward had nothing to do with the hoax because he was still working the site after Dawson died, hoping to find more remains. To this day we only have ideas on who committed the hoax but no solid proof on who did it.
2. The main fault here is that the scientists who analyzed the remains didn't verify the findings. Arthur Woodward was highly respected at the time and people believed what he had to say They chose to believe in the Piltdown man because it fit into what they wanted to find. This lack of scientific verification was a major setback in evolutionary science when other findings were dismissed in favor of the Piltdown man.
3. After doubt about the validity of the Piltdown man began to rise, more research into the discovery done. One of the main tools they used was the fluorine absorption test which was how they discovered the true age of the remains. The amount of fluorine that is absorbed by the bone can approximately determine how long the bone was in the soil.
4. I say you could remove the human element from science to verify all findings. I wouldn't want to remove the human element though. Humans have a natural need for curiosity and discovery that machines and computers don't have.While humans can be prone to hoaxes, it is humans who find out the truth to these hoaxes.
5. Verifying your sources is a very important aspect of the scientific community, especially at the time of this discovery. In this day and age verifying your sources is still very important. Taking everything you read online at face value could leave you easily misinformed on a variety of different issues. As could be seen in this instance not verifying your sources could potentially setback the scientific community for decades. Always make sure you have verify your sources is a very important lesson to learn!
The guidelines specifically advised against the use of the term "missing link" as the significance of this find. Did you have a chance to review the background on this term to understand the problems with it?
ReplyDeleteYou do highlight the actual significance of this find, namely the early evolution of human brains. That is the point that needed to be made in place of the "missing link" claim, which is inaccurate.
Good discussion on the faults involved in the acceptance of this find by the scientific community, but what about the perpetrators of this hoax? What faults were involved in the creation of this hoax in the first place?
Good description of the fluorine analysis. Other than better technology, what about the scientific method itself helped to uncover the hoax? Why were scientists still investigating this find some 40 years after it was uncovered?
"Humans have a natural need for curiosity and discovery that machines and computers don't have."
While I disagree that we could take the human factor out of the scientific process, I agree with this statement and suggest that traits like "curiosity" are positive factors that you would not want to take out of the scientific process. Not everything that humans bring to science is negative.
Good life lesson.
I like when you say, "While humans can be prone to hoaxes, it is humans who find out the truth to these hoaxes." I think this is an extremely important reason that the human element shouldn't be taken out of science. Even if it isn't necessarily a hoax we are talking about, machines and computers malfunction. If it weren't for humans being able to catch errors and correct them, all kinds of errors and hoaxes could possibly go on forever without being discovered. Although humans make errors, they are capable of admitting their faults and have the ability to correct them.
ReplyDeleteI feel as though without the human element, science would be just numbers rather than people trying to discover new things. I really enjoyed your point #4 with how humans are the ones who can figure out of if it is a hoax. Great life lesson! People need to learn how to verify and ask questions when theyre doubting something or someone.
