If you’ve ever gone skinny-dipping and had the creepy feeling you were being watched, you were right. The green slime floating on the surface of the water and coating the rocks was watching you. And it was doing it using eyes similar to your own human ones. That’s according to new findings by a team of scientists from…
Long ago, a clan of hardy microbes called cyanobacteria helped terraform the lifeless Earth into a vibrant biosphere. Today, the very same critters could be the key to colonizing Mars.
2.5 billion years ago, the Sun was basically invisible from the Earth's surface. Microbes in the oceans pumped methane into the atmosphere, creating a giant cloud of smog that covered the entire planet. Yes, the whole world turned into LA.
About 2.5 billion years ago, our planet had virtually no oxygen, and lifeforms were primitive. Then, oxygen levels suddenly spiked, the entire landscape of the planet changed, and we were on our way to complex life. Now, at last, we know why.
Around 2.4 billion years ago, the ancestors of bacteria took over the oceans and began photosynthesizing, creating massive amounts of oxygen where before there had been barely any. This was the Great Oxygenation Event, which made all subsequent life on Earth possible. All life except . . . yeast.
In mysterious sinkholes beneath the waters of Lake Huron, scientists have been exploring strange pockets of life that shouldn't exist on present-day Earth. The microbes researchers have found would have been perfectly comfortable on the Earth of 3 billion years ago, before we had oxygen in the atmosphere.
We all know how important carbon and oxygen are in the development of life on Earth. But millions of years ago, there wouldn't have been enough oxygen for animals to exist. What changed?
Life on Earth might actually be Martian — or Europan, or Titanese. Or maybe our ancestors came from outside our solar system, flung up from a distant planet (perhaps Caprica?) billions of years ago and migrated to Earth. It all sounds far-fetched, but new research suggests microbes can survive an asteroid impact big…
