10 Ways Earth Once Looked Like An Alien Planet

by Makr Oliver

Before humans, the world was a very different place. Our planet didn’t always look the way it does now. It’s gone through some incredible changes over the past 4.5 billion years—and they’re even wilder than you’ve imagined.

If you could step back in time and stand on the Earth millions of years ago, you wouldn’t just see a few different animals. You’d see an alien planet pulled straight out of a science fiction story.

New Zealand | Earth has a brand-new continent called ‘Zealandia,’ and it’s been hiding in plain sight for ages

by Dave Mosher

Kids are frequently taught that seven continents exist: Africa, Asia, Antarctica, Australia, Europe, North America, and South America.

Geologists, who look at the rocks (and tend to ignore the humans), group Europe and Asia into its own supercontinent — Eurasia — making for a total of six geologic continents.

Welcome to the age of the Anthropocene

Is the «Anthropocene» an exercise in geological bureaucracy or something sociologically more significant? PROFESSOR TIM NAISH explains.

Pressure is mounting on the guardians of the Geological Time Scale, the International Union of Geological Sciences (IUGS), to formally recognise a new epoch in Earth’s history.

Greenland | Hints of oldest fossil life found in Greenland rocks

How long has Earth harbored life? Chemical signatures found in hardy microscopic crystals called zircons point to a beginning about 4.1 billion years ago. But finding fossilized remains of microbes—undoubtedly the creature of the day—is a far more difficult task. Now, scientists say they have identified fossilized microbial mats, called stromatolites, in Greenland that date to about 3.7 billion years ago—nearly 300 million years older than the previous fossil record holder. The find may help guide scientists searching for life on other planets.
