In 1912, Charles Dawson (an amateur archaeologist) conducted a hand-dig at a gravel pit in Piltdown, a little village in England. Dawson had found what he claimed to be the fossilized remains of a human skull. Dawson then had invited Arthur Woodward, a leading geologist from the Natural History Museum, and Father Pierre Teilhard de Chardin, a French paleontologist, to join his dig at Piltdown. Through that summer, they made what was deemed "astonishing finds." There, Charles Dawson found a sensational jawbone fossil he claimed belonged to the ancient piece of human skull he had discovered previously.
In 1917
Dawson discovered another skull and tooth, labeled "Piltdown Man Two"
this was taken as additional evidence that his discoveries were legitimate. This
jawbone did not look to be human, but something closer to an ape in structure.
The teeth implied human characteristics, as they were ground into the shape of
human molars, from grinding and crushing food over time. The find was
incredible, for the time, and caused a lot of excitement in the field of
science. It was viewed as the "rarest and most treasured find" of
paleontology, and seemed to express some kind of evolutionary connection
between apes and humans backing the theory of evolution, and even more so
proving the theory of evolution to be true, by providing the trunk between the
roots and the branches. In England, it
was widely celebrated by the scientific community because (finally) there was
evidence that England had ancient human remains just as France, Germany, and
Asia. What was particularly important to England was the fact that these
remains dubbed the "Piltdown Man"might even be the oldest human
remains found to date.
With assertion from England's
leading anatomist, Arthur Keith, the discovery of the jaw and skull bones appeared
to support the theory that the development of large brains came before the
development of upright walking in human evolution. This was extraordinarily
important to the field of science and to the field of human evolution. The findings
of fossilized remains continued unchallenged until the death of Charles Dawson
in 1916.
Contradicting evidence to the
findings of Piltdown Man began appearing in the 1920's when, in places like Asia
and Africa, where a number of ancient human remains began to be discovered. The
contradicting evidence came in the fact that the newly discovered human remains
were not as old as Piltdown Man, but was far less human. At that time there was
insufficient technology to distinguish whether the remains of Piltdown Man were
just a bizarre phenomenon in human evolution or a hoax.
In 1949 new technology allowed for
a better method of dating the remains by measuring the fluorine content of the
fossils. This method of chemical analysis had been devised in 1939 by Kenneth
Oakley. Oakley found that Fossils absorb fluorine from the soil and water
around them, so fossils found in the same area should be around the same
age. 10 years after its discovery,
Oakley was able to use the measurement of fluorine to reveal that the
fossilized remains that were considerably younger than previously proclaimed (50,000
vs. 500,000), thus further confusing the scientific community.
Then in 1953, after World War ll technology advanced to where scientists could date the remains and they found that they were much younger than expected and that the remains had been found to be tampered with. The jaw bones were an easy give away that it was an Orangutan jaw had been removed, the teeth had been filed, and the fossil had been stained to make it appear older than it actually was. Scientists were shocked and in the fields of human evolution further discovered telltale signs that this was certainly a hoax. The scientists in this field have reacted by being aware that these hoaxes are certainly possible and to watch out for foul play. It was deemed the fossilized jawbone had been stained to appear older, and pieces of the bone had been cut off after fossilization. Additionally, the teeth had been filed down to resemble human molars. The jawbone actually belonged to a female orangutan less than a hundred years old, but pieces of the jaw that would have indicated this were broken off. In 1959 Carbon-14 dating became available and it was then revealed that the skullcap "fossils" were only about 1,000 years old and were really just old bones.
This physical evidence was
very important to the field of evolution, and more solid than the
circumstantial evidence. Scientists were shocked that this could happen, but it
brought to light that scientists are human, subject to pride and self-interest,
and are capable of lying to further their careers as seen in the particular
case of Piltdown. It had previously been thought that scientists would not
provide false science, but it happened, and now scientists are more scrutinized
in their analysis of scientific evidence. Unfortunately, this gives further strength
to groups that are against science, and specifically against evolution. It can now
be argued, that scientists lie and therefore all scientific evidence cannot be
taken as fact until verified by a second source.
I don’t believe that it’s possible
to remove the “human nature” factor from science because humans propose new
theories from their discoveries. Even though the theory might be false at first
but it is natural for humans establish a hypothesis through trial and error. There
will likely always be someone who revisits the theory that can prove, disprove,
or improve it.
I have learned that it is important
to question things when in doubt, not taking everything at face-value,
especially important discoveries such as the "Piltdown Man".
Discoveries should be carefully analyzed by multiple scientists that can assist
in concluding a reliable theory. From the” Piltdown Man” hoax, a lot can be
learned in regards to using verified sources. Maybe if the scientists in
England in the early 1900's had taken their own skepticism more seriously, they
would have been more resourceful and determined in their evaluation of the Piltdown
Man remains it would have revealed it as a hoax sooner than 40 years later.
I agree with your comments that this type of situation makes a stronger case for those people and groups against science, more specifically evolution. It just gives them more leverage to say that scientists lie to create their own version of human history.
ReplyDeleteI also like that you brought up the fact that humans bring a "thinking" or "theory" part to science. This is a very important factor that humans contribute. My initial idea was more of the physical part; that without humans we would not have discovered such things as fossils. But thanks for bringing to my attention another very important issue. Great point!
i also agree with you that humans make up the whole theory aspect of science it is very important to have that factor because as human being we can only go forward with our findings. i also loved the pictures you used, it really set the right tone for this post, almost like a crime scene.
ReplyDeleteIn general, good synopsis and great job highlighting Keith's pet theory that humans evolved large brains before other human traits. That, along with being the first hominid found on English soil, represents the significance of this find, had it been valid.
ReplyDeleteWith regard to this comment:
"...and seemed to express some kind of evolutionary connection between apes and humans backing the theory of evolution, and even more so proving the theory of evolution to be true, by providing the trunk between the roots and the branches."
The connection between humans and non-human apes, by this time, was not in question. The question was not "if" there was a connection, but "how" humans descended from that common ancestor with modern non-human apes. That is why the point of Keith's theory was so important. It explains "how" humans evolved from the common ancestor, with large brains evolving first.
Good discussion of the human faults involved in this event.
"It can now be argued, that scientists lie and therefore all scientific evidence cannot be taken as fact until verified by a second source."
"Lie" is a strong word, but it certainly does appear that someone is lying here. More importantly, it is good to recognize that humans can be swayed by ambition and greed. Whether or not they produce false information knowingly or are unaware that their findings are skewed by bias, your point about independent secondary confirmation is well noted.
You do a good job of discussing the new technology and ongoing discoveries that helped to uncover the hoax, but why were they still studying this find some 40 years after it was discovered? What positive aspect of science does that represent?
Good discussion of the human factor and good conclusion. Other than a couple of points, good post.
Laurie, thanks for the input, yea, I did forget to mention the reason for the 40 year investigation. I'm com'in on stronger now though.
ReplyDeleteThanks again!
:-) Thank you for the reply.
