Human intelligence has evolved over the years. Piece by piece, we are solving the mysteries of the past and learning from it. Here are seven of these resolved issues that baffled the minds of the early generations.

Lucy is the human’s early ancestor but the discovery of her fossils in 1974 in Ethiopia has puzzled the scientists because of great bone damages. In 1982, anthropologist Donald Johanson of Arizona State University in Tempe, and his team, attributed the bone damages to fossilization. But paleoanthropologist John Kappelman of the University of Texas at Austin reported that Lucy’s bone damages were due to a fall. Kappelman believed that Lucy fell from a 13-meter height while climbing or sleeping.

Amelia Earheart suddenly went missing in her quest to fly across the world. In 1940, skeletons were found in the uninhabited Nikamaroro Island in the Pacific. British authorities believed that it was of a male. However, The International Group for Historic Aircraft Recovery (TIGHAR) discovered original files in 1998 obtaining the bone measures of the discovered skeletons. The measures have a radius-to-humerus ratio of 0.756, close enough to the average 0.73 for women born in the late 19th century.
Earheart was born in 1897 and was four month in her 29,000-mile trip on her last appearance on radar on June 2, 1937.
Through the findings, experts concluded that Amelia Earhart may have survived the plane crash and may have lived as a castaway in the island before dying of some unknown causes.

The mystery of Déjà vu – the experience that feeling that something happening today had happened before – seem to have been solved by researchers from the University of St. Andrews. Researchers found that déjà vu is the brain’s technique to make sure that memories are correct. An MRI of the frontal region of the brain showed activity during a déjà vu. Stefan Kohler of the University of Western Ontario in Canada believes that it’s a kind of conflict resolution.

Hundreds of rocks that weigh as much as 700 pounds are moving across the Racetrack Player Lake in Death Valley. The rocks move due to natural causes and not of some mysterious spirits. Researcher Richard Norris and co-author Jim Norris solved this mystery in 2011 after observing the rocks for two years.
Shallow waters of about 7cm cover the lake and form thin ice sheets at night when temperature goes very low. The rocks move along the tiny ice sheets which melt in the morning leaving the rocks in different positions a day ago. The rock trails are left in the soft mud.

The one considered as the “Patient O” of AIDS was wrongfully known as the “Patient Zero.” Gaetan Dugas, a Canadian flight attendant was wrongfully blamed for the epidemic in the 80s because of the tag referring to him. Patient O actually means he was from outside California while Patient Zero means he was the first bearer of the virus. HIV has been around since 1967 before Dugas was diagnosed with the virus. Sadly, the mistake between O and Zero took decades to correct.
