The Piltdown man (early human) fossils were found in a gravel pit at piltdown, east Sussex, england in 1912 by Charles Dawson. During the time that the piltdown fossils were discovered that scientific community cheered greatly and accepted piltdown man as the missing link between apes and humans.Arthur Keith also cheered greatly when he heard about the piltdown fossils, because that provided him with the evidence he needed to prove his theory of human evolution. Charles Dawson and others involved were happy that now England had ancient human fossils of their very own.

The piltdown man hoax was discovered in the 1950's but clues leading to the discovery of the hoax's began in 1949 after world war 2, when new technology emerged that helped date fossils more accurately. In 1949 they began to measure the fluorine content of fossils scientists could get a better date on the fossils. When the piltdown man fossils were given a fluorine test the results showed the fossils were only one hundred thousand years old, instead of the millions of years old it would expected to be given the location were it was found. But it was in 1953 when a full series of scientific tests were conducted on the piltdown fossils, which lead to the exposure of the hoax. The testing showed that staining on the bones was superficial, that some of the engraves in the bones were craved with a steel knife after it was fossilized, and the more noticeable find was the teeth using a microscope they discovered that they teeth were filed down to make them look similar to the ware of human teeth. And the jaw bone found was dated less than 100 years old and came from a female  orangutan.  The discovery of the hoax put the scientific community into shock, they couldn't understand why anyone would create fake fossils. It also lead them down a path of confusing as they wondered why the piltdown man fossils wasn't similar to other early human fossils uncovered in other parts of the world. Arthur Woodward one of Charles Dawson's partners who assisted in the find was confused when he kept digging in piltdown for decades after Dawson died and couldn't find anything after Dawson passed away.

Being humans we all have faults which cause all of us to make mistakes whether they are intensional or not.  In this scenario, pride, and lack to details are some of the faults that were present. Lack of details occurred when they uncovered new early human fossils from different parts of the world they should have compared them to the piltdown discovery to see if there were any underlining similarities between the fossils which should have been present. Same basic jaw structure, teeth, and format of the skull would have been some basic things to look for when comparing the piltdown man and other early human fossils finding from different parts of the world. Pride was by far the biggest fault involved with this scenario, pride for his country and wanting to be recognized by the scientific community is what most say is the major motivation they say that Charles Dawson had to making the forgeries. He wanted to be accepted by the scientific community for his findings and also wanted England to have one of the earliest human fossils to ever be found he felt such discoveries would be England on top of the scientific community at the time. 

Scientific objection and testing of the original hypothesis is what lead to the finding of the piltdown man hoax, but not without the help of new emerging scientific technologies new fluorine testing and new discoveries with microscopes are some of the tools that enabled scientists to find the key clues that lead them to the truth. the Fluorine tests enabled them to test the natural level of fluorine in the fossils which in turn allowed them to calculate the date of the fossils.

There is not any way to completely remove human factor from science even if every factor of science was controlled by machines and computers they still require input from humans to do their calculations, and if we input something incorrectly into a computer then it shall not compute the given equations or function correctly.  no i wouldn't want to the human factor to be removed from science because although we make mistakes and mis calculations it allows us to fix problems by learning from our mistakes and expanding our knowledge.

The lesson I can take from this event is to be careful what I hear from people it doesn't matter who its from, but from any information I hear from someone else its always a good thing to do some back up research of your own just to verify that information you are receiving from someone else is credible and understandable.
