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. Life was anaerobic, meaning that it did not need oxygen to live and grow.

Home "Darwin's Origin of Species is one of humanity's crowning achievements." James T. Costa "The Theory of Darwinian Evolution, which continues to be refined by thousands of scientists working around the world, is the basis for the entire field of modern biology. Today it is one of the most important concepts in science and probably in the history of human thought." “(The Origin is) a truly great book, one which after a century of scientific progress, can still be read with profit by professional biologists.” "The name of Charles Darwin stands along side of those of Issac Newton and Michael Faraday; and like them, calls up the grand ideal of a searcher after truth and interpreter of nature." "Charles Darwin's Origin of Species is one of the most precious books in the entire library of our species." "If I were to give an award for the single best idea anyone ever had, I'd give it to Darwin, ahead of Newton and Einstein and everyone else." "Arguably history's most influential book."

Watch A Stunning Video Of Humanity's Effect On Earth According to scientists, we’re currently in the geological epoch known as the Holocene, which has lasted for the last 12,000 years. The Holocene encompasses the rise of humanity since the last ice age. But some scientists think we have actually entered a new era, called the Anthropocene--an era in which the world no longer shapes humanity, but in which humanity shapes the world to its own purpose and does so to such an extent that it will have permanent effects of the geological record of our planet. As scientists debate the merits of declaring we are in a new epoch (these things take time and lots of arguing), humanity plods on, continuing to make a massive impact on the planet. As the animated globe turns, you can see what man has wrought upon the planet. For some larger context, the video below has a soothing British woman describing a little more about what the Anthropocene means and how it came to be.

I - LES NIVEAUX DE LA SELECTION : de la molécule à l’individu - Le Cactus Heuristique L’histoire de la sélection naturelle Charles Darwin (photo à gauche) défini la notion de sélection naturelle comme la « préservation des variations favorables dans la lutte pour la vie, et le rejet des variations préjudiciables ». Le concept de sélection naturelle postule un tri de certains caractères biologiques au cours des générations, qui découle du fait que les porteurs de ces caractères se reproduisent mieux que les membres de la population qui en sont dépourvus. Pour induire la sélection d'un caractère biologique particulier dans une population, il faut que ce caractère varie d'un individu à l'autre, que cette variation individuelle soit héritable, et que cette variation soit corrélée à celle du succès reproducteur de ses porteurs. A partir des connaissances acquises sur l’hérédité, la sélection naturelle a ensuite été divisée en 3 modes d’action agissant sur la distribution des phénotypes dans une population: Pourtant, en 1945, le biologiste suédois G. S.J. En 1980, L. Les gènes

Crazy Maps Show The World Organized By Human Activity Ever since Gerardus Mercator created his iconic map of the world in 1569--the one that first enabled ships to navigate at sea without getting lost--people have been drawing maps using the same fundamental concept of conveying physical space. Cartographers have gotten more sophisticated over time. They’ve figured out how to distort that space, how to portray that Massachusetts has more electoral votes than Wyoming, or that countries closer to the equator are larger than we think. But for hundreds of years, we’ve been tethered to the idea of looking at the world through the shape of its land. Now that there’s virtually none of that left to explore and discover, it may be time to start thinking about our world in new visual ways: not according to physical space, but to how people are distributed across it, and what their presence can tell us about global poverty, health inequality, environmental impacts, and geopolitics. Take a look at this map of the world:

Merrylin Cryptid collection merrylin from Simon Lewis on Vimeo. Merrylin Cryptid collection is the study and documentation of the evolution and biology of unclassified species and research pertaining to prehistoric human and non human civilization. In 2006, a trust was set up to analyze and collate a huge number of wooden crates found sealed in the basement of a London townhouse that was due to be demolished. Seemingly untouched since the 1940′s, the crates contained over 5000 specimens of flora and fauna, collected, dissected, and preserved by many forgotten scientists, professors and explorers of obscure cultures and species. The collection also housed many artifacts of curious origin, fragments of civilizations that once ruled the earth, of ideas and belief systems better left in the past.
