EDMONTON—A closer look at some unimaginably ancient fossils suggests complex life may have evolved much earlier and more quickly than scientists previously thought.

Greenland and Antarctica are a long distance away but newly-released research suggests the accelerating disappearance of their ice caps will have a major—and underestimated—effect on extreme weather in Canada.
One of nature's greatest migrations may be returning to health after a stunning growth in the number of monarch butterflies that fluttered across North America last year.
But if populations of the striking black-and-orange aviators are starting to recover, it's no thanks to Canada, said Carolyn Callaghan of the Canadian Wildlife Federation.
More than half the food produced in Canada is wasted and the average kitchen tosses out hundreds of dollars worth of edibles every year, says a study researchers are calling the first of its kind.
“It's a lot of food,” said Lori Nikkel of Second Harvest, the Toronto-based group working to reduce food waste that commissioned the study.
“We waste more food than we consume.”
Half the country's chinook salmon populations are endangered and most of the rest are in decline, according to a science committee that monitors the health of wildlife populations.
The Committee on the Status of Endangered Wildlife in Canada reported yesterday that of Canada's 16 Chinook populations, eight are endangered, four are threatened, and one is considered of special concern.
A study suggests most Canadian cities have yet to assess the threat posed by climate change despite being the most exposed to any weather disasters it could cause.
A survey of 63 municipalities of all sizes from coast to coast found major gaps in how most are preparing for coming conditions and in how they are reducing their contribution to the problem.
With more depressing results that suggest climate change threatens half of Canada's songbirds with significant habitat loss, you might expect one of the new study's authors to be downcast.
But Jeff Wells isn't.
Two injured Inuit hunters huddled for three days with the body of their friend who was killed by a polar bear as four other bears circled their camp.
“They had to sit tight,” said Rob Hedley, administrator for the hamlet of Naujaat, Nunavut, where the hunters were from.
“It was pretty scary," he noted. "They didn't sleep and they were out there for a while.”
New research is upending old assumptions about what the ancestors of today's Inuit learned from Viking settlers.
And the techniques researchers have developed to show that ancient Dorset and Thule people knew how to spin yarn centuries before the Norse were thought to have taught them could change the way archeologists think about Arctic history.
The largest and most precise study yet done on acid emissions from Alberta's oilsands suggests they could eventually damage an area almost the size of Germany.
The study finds that in 2013 more than 330,000 square kilometres in northern Alberta and Saskatchewan absorbed acid deposits high enough to eventually damage life in rivers and lakes.
