Oldest Water Cache Ever Discovered May Hold 1.5 Billion-Year-Old Life

After kindly asking a group of Canadian miners for a sample of some water they’d struck, a team of scientists who had been investigating similar finds discovered that the fluid they were looking at may have been sealed up for 1.5 billion years.


How Dinky Feathers Helped Running Dinosaurs Evolve Into Flying Birds

If you’re a believer in science, you’re probably at least vaguely aware that prevailing theories posit that the birds of today are distant relatives to the dinosaurs that died off millions of years ago.


How Human Evolution Prepared Us To Survive Future Disasters

We may be in the early stages of a disaster so profound that it could kick off a mass extinction. Does that mean humanity is doomed? No. Scientific evidence suggests that humans will survive. Find out why, in this excerpt from Scatter, Adapt, and Remember: How Humans Will Survive A Mass Extinction.


Plants Are Green Because Chlorophyll Is An Evolutionary Champ

A few weeks ago, Minute Earth raised the question of why plants are green. After all, their green colour means they’re reflecting green light, so wouldn’t black plants that absorb all light be most efficient?


Swallows Seem To Be Evolving To Avoid Cars

Swallows that nest on roadsides appear to have evolved shorter wings to help them manoeuvre better and avoid cars, claim a team of scientists from the University of Tulsa in Oklahoma. They have been studying cliff swallows that live near roads, and observed that the number of vehicle-killed birds has declined over the past three decades, despite the fact that the overall population has increased.


Wrinkly Fingers Evolved To Help You Grip Wet Objects

If you’ve ever sat in a bath staring at your fingers as they wrinkle involuntarily, you’re in good company. Now, a team of scientists has worked out why it happens.


The History Of Evolution Explained In Two Minutes

A lot has changed on the surface of the Earth over the past 4.5 billion years. This video explains the long, slow process that enabled simple cells to evolve into the creatures that inhabit our planet today.


Evolving Bigger Brains May Have Made Us Prone To Cancer

If it’s not one thing, it’s another: a new hypothesis floating around the scientific community suggests that evolving bigger brains and superior intellect may have led to a dramatically elevated risk of cancer in humans. Thanks, brain.


The Placebo Effect Might Have Evolved To Save Us Energy

The placebo effect seems to make no sense: get mildly ill, take a dummy pill without knowing it’s ineffective, and you’ll recover in much the same way as someone taking real drugs. But new evidence suggests that we might have evolved the placebo effect to save energy.


Australian Rocks Confirm That Life On Earth Is 3.5 Billion Years Old

Science has shown that the Earth is 4.5 billion years old. But what about the life that exists on it? Since 2006, we’ve thought that biological activity in the form of stromatolites — ancient layered geological structures — first appeared here 3.5 billion years ago, and now we have even more evidence to back that up.
