A three-century record of penguin poop shows that the flightless birds probably thrived during the Little Ice Age, a Chinese research team says. Contrary to some reports that the Adelie penguin fared better in warmer conditions, when sea ice broke up, Earth scientist Zhou-Quing Xie of the University of Science and Technology in Hefei, China, says that from 1490 to 1670, the middle of the so-called Little Ice Age, Adelies thrived on Ross Island off...

Given the short half-life of DNA, we may never have a Jurassic Park - but could we one day boast of an Ice Age Garden? Scientists have brought back to life a collection of roughly 400-year-old frozen plants recovered from melting glaciers in the Canadian Arctic. The feat, described in Proceedings of the National Academy of Sciences, shows that certain plants might be much tougher than previously thought, able to regenerate after centuries under ice. "Their structural preservation is exceptional," the study authors wrote.

SAN DIEGO -- Start digging into Southern California and you never know what you'll find. The fossilized remains of an Ice Age bison were found by a Caltrans construction crew near Pala Mesa in northern San Diego County. The crew was working on a construction project at Interstate 15 and California 76. Scientists say the remains are about 200,000 years old and are the first of their kind found in Southern California. In about six weeks, after more digging, the remains -- including skull and hip bones -- will be displayed at the San Diego Natural History Museum.

Would Ice Age man understand us? It may depend on the words we choose. Digging through languages in Eurasia for "fossil" words that have escaped erosion over time, researchers say they have identified an ancestral language that existed as far as 15,000 years ago. This ancient language, described in Proceedings of the National Academy of Sciences, may have given rise to several different language groups - including Indo-European, which boasts roughly...

First the good news: In the last 11,300 years, humans have endured a planet warmer than today's, even as they set about building their earliest civilizations. Now the bad news: That will no longer be true 87 years from now, according to scientists who have conducted a comprehensive analysis of the planet's climate history since the world's ice sheets began their most recent retreat from North America and Europe. New research into Earth's ancient climate is providing a clearer, more detailed view of how the planet's average surface temperature fluctuated over the period known as the Holocene epoch, which continues today.

Nearly 200 years after Charles Darwin wondered how a fox-looking wolf came to live on South American islands hundreds of miles from the mainland, scientists think they have the answer. The Falkland Islands wolf, the only land animal believed to have occupied the Falkland Islands before it was hunted into extinction in the 19 th century, trekked to its final home over ice sheets during the last ice age, researchers concluded. The wolf, Dusicyon australis , became isolated from its sister species, Dusicyon avus, on the South America mainland about 16,000 years ago, according to the study published Tuesday in Nature Communications.
