Some 375 million years ago, a unique fish existed with features in its head that helped pave the way for vertebrate animals to live on land, scientists said on Wednesday. Now, new research is providing the first glimpse at the internal head skeleton of Tiktaalik roseae. The transition from aquatic to terrestrial lifestyle involved complex changes not only to appendages (fins to limbs) but also to the internal head skeleton, researchers report in the recent issue of the journal Nature....

Scientists said on Tuesday the ice shelves in Canada's High Arctic have lost a colossal area measuring 19 square miles after it broke away last month. The remaining shelves attached to Ellesmere Island, which have lasted for thousands of years, have seen almost a quarter of their cover break away. The Markham Ice Shelf, one of just five remaining ice shelves in the Canadian Arctic, split away from Ellesmere Island in early August.  Scientists also reported that two large chunks totaling...

Eight square miles worth of giant ice sheets broke off an ice shelf in the Canadian Arctic last week, and scientists said on Tuesday that global warming could be to blame. Experts say temperatures in large parts of the Arctic have increased far faster than the global average in recent decades. In one of the northernmost parts of Canada, the ice broke away from the shelf on Ward Hunt Island, which is a small island just off giant Ellesmere Island. It was the largest fracture of its kind...

MINNEAPOLIS -- Will Steger is fit and trim at 63, planning his latest grueling expedition to the far reaches of the planet, and loathe to take a vacation. But he's getting ready to turn things over to the youngsters. When the famed Minnesota explorer leads an expedition to the Canadian Arctic early next year, to draw attention to retreating glaciers and other apparent signs of climate change, the oldest of the six explorers accompanying him will be 28. The idea is to focus on "emerging...

WASHINGTON -- Ponds that have provided summertime water in the high arctic for thousands of years are drying up as global warming advances, Canadian researchers say. Falling water levels and changes in chemistry in the ponds first were noticed in the 1990s, and by last July some of the ponds that dot the landscape were dry, according to a report in Tuesday's Proceedings of the National Academy of Sciences. John P. Smol of Queens University in Kingston, Ontario, and Marianne S. V. Douglas of...

LONDON -- Scientists have caught a fossil fish in the act of adapting toward a life on land, a discovery that sheds new light one of the greatest transformations in the history of animals. Scientists have long known that fish evolved into the first creatures on land with four legs and backbones more than 365 million years ago, but they've had precious little fossil evidence to document how it happened. The new find of several specimens looks more like a land-dweller than the few other fossil...
