2015/7/9
Reconstructions of Holocene relative sea level (RSL) have valuable applications in a number of topics within the Earth sciences, including calibrating and constraining geophysical models of Earth's rh...
Nineteenth and Twentieth Century Changes in Sea Level
Nineteenth Twentieth Century Sea Level
2015/7/9
Following the Last Glacial Maximum (25,000–20,000 years ago), sea level rose at rates on the order of several tens of millimeters per year at times, and increased overall by over 130 m. However, melti...
How the Mammoth Got its Wool: Genetic changes are identified that helped the woolly mammoth survive in the Arctic（图）
Mammoth Got its Wool Genetic changes identified woolly mammoth survive Arctic
2015/7/13
Evolutionary change in a gene resurrected in the lab from the extinct woolly mammoth altered the gene's temperature sensitivity and likely was part of a suite of adaptations that allowed the mammoth t...
