Its time we look again at the important arguement of determining fake crop circles from genuine ones. Most of the public have forgotten there is valid research which can separate both from each other.
As the public have not been told the full story about crop circles they often instantly disregard the whole phenomenon as the work of hoaxers. The media and the hoaxers over the years are responsible for the this biased opinion. Once again, i would like people to remember the point of disinformation - 'to confuse but not necessarily disprove' - when you discredit the topic it becomes confusing and it just takes a few seeds of doubt for the public to drop interest it all-together. This is exactly they want to happen with crop circles, but if you bother to look further and actually study crop circles you find out there is alot more going on here than just pretty shapes.
With the advent of GPS and plotting decides more sophistated fakes have been able to have be created over the years.Yet still the genuine crop circles return as they have for over a thousand years (previously known as objects like the 'moving devil') , with recorded history going back to 800 AD in Wilshire UK - where the majority of crop circles still appear to this day.
Those characteristics include:
*Abnormal enlargement of cell wall pits in the bract tissue of crop circle plants
*Lateral and longitudinal enlargement, and bending and stretching of plant stem nodes in crop circle plants
*Stunting and malformation of seeds in crop circle plants
*Crystal growth in crop circle soil that, under laboratory conditions, could be achieved only at temperatures that would incinerate all plant matter
* Magnetic anomalies inside crop circles.
I could go on about this further but i suggest you listen to Nancy's research below and her lectures on 'genuine' crop circles. Similarly, there are many other scientific studys about crop circles underway worldwide and so the phenomenon is not as easily explained away as Yahoo would like you to believe.
