本文发表在 rolia.net 枫下论坛More than 4 billion years ago, the most important event in the history of the earth took place: the ocean was born. It completely transformed the planet, creating a watery oasis that gave rise to the air we breathe, our climate, and the stunning array of life, including the critical species, that first crawled out of the ocean, to inhabit land.
"We're looking at an animal that's really at the base of the branch in the tree of life that leads to all limbed animals, and, and we're limbed animal."
The story of the ocean is the story of mass extinctions and of astonishing survivals in one of the most beautiful and mysterious parts of the planet. Ultimately the history of the ocean is our own history, and today we're just beginning to understand its complexity and the immense influence it has on the planet and on our own survival.
"Our vast ocean stretches out over space and time. It's almost as old as the planet itself. Yet for most of us, the ocean is a shoreline, a watery surface, a mystery. There's an amazing world beneath these waves, but it's fragile and threatened. In this four-part series, we'll join the scientists who are unlocking the secrets, and exploring the wonders of this most critical life forest on the planet, the ocean."
We live on the blue planet which is almost all of ocean. A water planet that is unique among the cosmos. But where did all this water come from? And how did it transform our planet? Nick Ailes (?), a professor of Geology at the University of Toronto, has a good idea of what this planet looked like 4.5 billion years ago.更多精彩文章及讨论，请光临枫下论坛 rolia.net
