The illustrated book of pigeons. With standards for judging. The Animated Life of A. R. Wallace. How Darwin’s view from his bedroom window ushered in a scientific revolution. The room that Charles Darwin used to monitor his revolutionary biological experiments has been recreated more than 100 years after it was closed and its contents were dispersed.

How Darwin’s view from his bedroom window ushered in a scientific revolution

Visitors to Down House, the great scientist’s home in Kent, will now be able to sit in the great bedroom where Darwin once monitored the research that helped him to develop his theory of natural selection. Curators from English Heritage have used decorators’ inventories, family photographs and paint analysis to recreate the likely wallpaper, carpets, chintz curtains and giant four-poster bed that would have adorned Down House’s great bedroom. There is also a sofa based on the one that Darwin used while listening to his wife, Emma, reading extracts from popular novels, as well as a bookcase that includes a volume of Darwin’s favourite book, Mark Twain’s The Celebrated Jumping Frog of Calaveras County.

Another example of his bedroom-monitored work is provided by climbing plants. Wallace, Darwin, and Evolution: The Real Story. Book of the Week: The Malay Archipelago, by Alfred Russel Wallace In 1858, Journal and Proceedings of the Linnean Society: Zoologypublished a paper proposing what would later be recognized as a revolutionary scientific concept: the theory of Evolution by means of Natural Selection.

Wallace, Darwin, and Evolution: The Real Story

If we were to ask you who penned this publication, chances are your response would be Charles Darwin. You would, however, only be half right. While it is true that this 1858 publication represented 20 years of Darwin's contemplation and conclusions on the process of natural selection (which culminated in the monumental work On the Origin of Species published just one year later in 1859), the Linnean Society piece was actually co-authored by Alfred Russel Wallace, who independently conceived of the theory of natural selection.

Darwin's Evolutionary Trees. The Museum's library is part of the Darwin Manuscripts Project, which aims to digitize the papers, manuscripts, and correspondence of Charles Darwin.

Darwin's Evolutionary Trees

Among these papers are some of Darwin's trees of life—visual representations of how organisms are related— that represent the scientist's brainstorming about his theories. Charles Darwin published only one tree of life in his lifetime, a foldout that appears in On The Origin of Species. But Darwin drew many trees over his career, including this one for primates, the last one he was known to produce, dated April 21, 1868. Scholars suspect that Darwin, not a skilled draftsman, was likely using his trees as a tool for working out relationships in his own mind—a form of thinking out loud. Trees of life like this one helped Darwin refine his ideas visually.

Darwin's Early Love. The Origin of Species: The Making of a Theory. The Darwin Doodle That Changed Biology. Charles Darwin relied on his notebooks.

The Darwin Doodle That Changed Biology

In them, he jotted private ideas, questions, fragments of conversations, and sketchy drawings related to his thinking on "transmutation"—what we now call "evolution. " The notebooks reveal a great mind homing in on a great idea: Plants and animals are not fixed and unchanging. Instead, all species are related through common ancestry, and they change over time. Early Tree of Life: Charles Darwin's best-known evolutionary tree, describing relationships among groups of organisms Many of these notebooks are now accessible through the Darwin Manuscripts Project, an effort at the American Museum of Natural History to digitize Darwin's scientific writings in close collaboration with Cambridge University Library. Once Darwin started thinking seriously about evolution, he grasped its essentials with astonishing speed. Below is the full notebook page, with a transcription of the text: I think To do this & to have many species in same genus (as is).

Darwin-groupie. The Seeds That Sowed a Revolution - Issue 10: Mergers & Acquisitions. When the HMS Beagle dropped anchor on San Cristobal, the easternmost island in the Galapagos archipelago, in September 1835, the ship’s naturalist Charles Darwin eagerly went ashore to gather samples of the insects, birds, reptiles, and plants living there. At first, he didn’t think much of the arid landscape, which appeared to be “covered by stunted, sun-burnt brushwood…as leafless as our trees during winter” But this did not put him off. By the time the Beagle left these islands some five weeks later, he had amassed a spectacular collection of Galapagos plants. It is fortunate that he took such trouble. Most popular narratives of Darwin and the Galapagos concentrate on the far more celebrated finches or the giant tortoises. Yet when he finally published On the Origin of Species almost 25 years later, Darwin made no mention of these creatures.

But when the botanist began to study the leaf structure and the flowers and seeds in minute detail, he was in for a big surprise. Minions - Official Trailer (HD) - Illumination. Rap Evolution.
