Shrooms gay pride colors2/4/2024 Or are we?Īlien astrobiologists could have noticed the Proterozoic transition by detecting the dramatic destabilization of Earth’s atmosphere. Everything accelerated further 542 million years ago with the Cambrian Explosion of complex life of plants and animals-the Phanerozoic Eon. “That’s when life took over the planet,” said Grinspoon. Then 2.5 billions years ago the Proterozoic Eon unleashed “the Great Oxygenation Event” caused by cyanobacteria adopting solar energy (photosynthesis). They won’t look for signs of mere geological epochs on other planets they’re looking for eon-scale transitions like the three that Earth has gone through in its 4.8 billion years, all caused by life.Ībout 4 billion years ago the Archean Eon began with the origin of simple life. Thanks to the growing human domination of natural systems on Earth, people say we are entering an Anthropocene Epoch, Grinspoon began, but what if the term “epoch” understates the consequence of what is going on? Astrobiologists recently learned that planet formation is the norm in the universe, and now they’re trying to find out if life formation is also the norm.
