British RAF pilots in the early 20th century were the first to spot the strange kite-like lines on the deserts of Israel, Jordan and Egypt from the air and wonder about their origins. The lines are low, stone walls, usually found as angled pairs, that begin far apart and converge at circular pits. In some places in Jordan the lines formed chains up to 40 miles long.
Were they made by some weird kind of fault? Ancient astronauts?
A new study of 16 of what are called desert kites in the eastern Sinai Desert confirms what many researchers have long suspected: The walls form large funnels to direct gazelle and other large game animals into killing pits. What's more, the kites are between 2,300 and 2,400-years-old, were abandoned about 2,200 years ago and are just the right size to have worked on local gazelles and other hooved game.
"The research shows that the construction of the kite was actually more sophisticated than it seemed before, their use was more diverse than we thought, and the ancients' knowledge of animal ethology was deeper and more intimate than one would think," said Uzi Avner of Ben-Gurion University-Eilat, in Israel.
"We have no doubt at all that the kites were built for hunting, not for any other suggested function."
