Understanding Evolution The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces. While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Read the rest of the story here | See the Evo in the News archive

Everything Dies, Right? But Does Everything Have To Die? Here's A Surprise : Krulwich Wonders... A puzzlement. Why, I wonder, are both these things true? There is an animal, a wee little thing, the size of a poppy seed, that lives in lakes and rivers and eats whatever flows through it; it's called a gastrotrich. It has an extremely short life. Hello, Goodbye, I'm Dead It hatches. Sad, no? It's a hydra. So we made one. I have so many questions. My friend Carl Zimmer introduced me to the gastrotrich in his introductory essay to Rachel Sussman's book, The Oldest Living Things in the World.

Chemist Adds Missing Pieces To Theory on Life's Origins The problem in imagining how RNA got started, Dr. Miller said, is that ribose is unstable, particularly when it is warm. Dr. Miller said he is preparing a new paper describing experiments that show that half of any quantity of ribose decays in a little over an hour at the boiling point of water. Even at the freezing point, the half life of ribose is only 44 years. Some scientists, including Dr. But Dr. Dr. "If you equate the probability of the birth of a bacterial cell to that of the chance assembly of its component atoms," Dr. de Duve wrote in his textbook, "A Guided Tour of the Living Cell," "even eternity will not suffice to produce one for you. The hard part, he wrote, was getting from the simplest chemicals to the first specialized cells, after which "it took no more than 150,000 generations for an ape to develop into the inventor of calculus."
