In 1953 scientists
subjected the find to chemical analysis which proved the ape-like jawbone was

which had been shortened to make them appear human-like. In addition, the
bones had been treated with chemicals to increase the appearance of their
age. It was quickly concluded that the jaw had been intentionally planted,

conclusively that the jawbone was from an Orangutan.
