The Darwin fish isn't merely a joke; in effect, it contains a testable scientific prediction. If evolution is true, and if life on Earth originated in water, then there must have once been fish species possessing primitive limbs, which enabled them to spend some part of their lives on land. And these species, in turn, must be the ancestors of four-limbed, land-living vertebrates like us.
Sure enough, in 2004, scientists found one of those transitional species: Tiktaalik roseae, a 375-million-year-old Devonian period specimen discovered in the Canadian Arctic by paleontologist Neil Shubin and his colleagues. Tiktaalik, explains Shubin on the latest episode of the Inquiring Minds podcast, is an "anatomical mix between fish and a land-living animal."
A high-altitude avalanche Friday killed 12 Sherpa guides and seriously wounded three in the single deadliest accident on Mount Everest, officials said. The avalanche took place just above base camp in the Khumbu Ice Fall. A group of about 50 people, mostly Nepali Sherpas, were hit by the avalanche at more than 20,000 feet, said Tilak Ram Pandey of the ministry's mountaineering department.
(MEXICO CITY) -- A powerful earthquake shook central and southern Mexico on Friday. The U.S. Geological Survey calculated its magnitude at 7.5 and said it was centered near the Pacific resort of Acapulco, where many Mexicans are vacationing for the Easter holiday.
An Associated Press reporter said it was felt strongly in the resort city but there were no immediate reports of injuries or damage.
The quake shook Mexico City for at least 30 seconds, with buildings swaying as people fled high rises and took to the streets. Because of the Easter holiday, that city was less crowded than usual.
