"Darwin's Bulldog", was no movie villain, and in this marvelous biography Adrian Desmond confronts us with his considerable complexity. Huxley, who was "never at peace unless he was fighting, never alive unless he was slaying", made a career of flogging bishops, pushing godless evolution, and trampling those who would impede his dream of a new social order guided by science. At home, however, Darth turned into 'Hal', devoted husband and father of seven. "He took the six-week break at home to clear the backlog. Here his only plague was a curly head poking round the door, wanting to play. Thomas Huxley was born in 1825 above a butcher's shop in Ealing, a small village near London, the youngest of six children.

And that’s a pity because he helped develop one of life’s most important scientific theories. The Evolutionist is Avi Sirlin’s first foray into historical fiction. So how did this Canadian lawyer come to be interested in the forgotten co-founder of evolution? Coincidence, really. He was 15 years into starting his own firm practicing immigration and criminal law when he got the itch to write – courtroom dramas make for good writing fodder, he explains in a Skype interview. He never got around to it, though, he just didn’t have the time.
Two screenplays later, he decided to tackle the genre of historical fiction. Alfred Russel Wallace, the forgotten man of evolution, gets his moment. Alfred Russel Wallace is far from a household name, but he changed the world.
Recovering from a bout of malaria on the remote Indonesian island of Halmahera, the young British biologist came up with an idea that would transform humanity's view of itself: he worked out the theory of natural selection. Wallace wrote down his idea and sent it to Charles Darwin, who had been contemplating a similar theory of evolution for more than a decade. Both versions were read to members of the Linnean Society in 1858. Today Darwin is the man who gets the lion's share of the credit for a theory that provides the mechanism to explain how a species can be slowly transformed into another. Wallace has been forgotten. On Thursday, Wallace's portrait – which has been kept for years in a storeroom – will be hung beside the grand statue of Darwin that overlooks the museum's main hall. Antonio Nobre: "É urgente que a colaboração surja nas ciências e tecnologias"
RIO - Um dos convidados do colóquio "Os mil nomes de Gaia", que acontece de 15 a 19 de setembro na Casa de Rui Barbosa, Antonio Nobre é o que se pode chamar de "cientista da terra".
Pale Blue Dot. Lynn Margulis. Lynn Margulis (born Lynn Petra Alexander; March 5, 1938 – November 22, 2011) was an American evolutionary theorist, taxonomist, bacteriologist, protistologist, and botanist, with advanced degrees in zoology and genetics.
She was known to the public as a science author, educator, and popularizer, and above all recognized as the primary modern proponent for the significance of symbiosis in biological evolution. Historian Jan Sapp has noted that, "Lynn Margulis’s name is as synonymous with symbiosis as Charles Darwin’s is with evolution. " In particular, Margulis transformed and fundamentally framed current understanding of the evolution of cells with nuclei – an event Ernst Mayr called "perhaps the most important and dramatic event in the history of life" – by proposing it to have been the result of symbiotic mergers of bacteria.
Biography Lynn Margulis was born in Chicago, to a Jewish, Zionist family. Her parents were Morris Alexander and Leona Wise Alexander. Forget Darwin? Was Charles Darwin a Plagiarist? Darwin’s Ghosts: The Secret History of Evolution. Today, scientists are extremely careful in making sure they cite others’ works, if not for ethical reasons because plagiarism destroys reputations and is potentially a career ender.
However, in the past for some scientists including Charles Darwin and James Watson, the public has controversially given them credit for game changing discoveries and catapulted them into rock star status. In Darwin’s Ghosts (Random House 2012), Rebecca Stott, an English and creative writing professor at the University of East Anglia, explores Darwin’s story and his actual role in the concept of natural selection. Specifically, she examines the truth behind a letter accusing Darwin of plagiarism. Random House’s publicity sheet accompanying the book states: One month after he finally published On the Origin of Species, in December 1859, Charles Darwin received a disturbing letter. In the English language, the nuances of word choice are important for science historians. Darwin & Adam Smith, Not Darwin & Marx. Why Are We Still Talking About Darwin? If someone in 2012 wants to criticize Henry Ford because he didn't know everything about automobiles a century ago, it's a little silly.
He knew what he knew given the science and the technology of his day - he revolutionized his field. Freud got a lot wrong about psychology but he created the only unified theory of psychology recognized by people today. Criticizing him is as quaint and pointless and irrelevant as someone criticizing a 19th century analysis of Coleridge - any researcher doing it is likely to get a "someone paid for them to write this? " response. In 2012, though, people are still trying to bash Darwin and their main argument is he didn't know everything. Untitled. Huxley the Darwin buldogg. Complexities of DNA repair discovered.
An international team of scientists led by UC Davis researchers has discovered that DNA repair in cancer cells is not a one-way street as previously believed.
Their findings show instead that recombination, an important DNA repair process, has a self-correcting mechanism that allows DNA to make a virtual u-turn and start over. The study's findings, which appear in the Oct. 23 online issue of the journal Nature, not only contribute new understanding to the field of basic cancer biology, but also have important implications for potentially improving the efficacy of cancer treatments. "What we discovered is that the DNA repair pathway called recombination is able to reverse itself," said Wolf-Dietrich Heyer, UC Davis professor of microbiology and of molecular and cellular biology and co-leader of Molecular Oncology at UC Davis Cancer Center. "That makes it a very robust process, allowing cancer cells to deal with DNA damage in many different ways. DNA repair. DNA damage resulting in multiple broken chromosomes The rate of DNA repair is dependent on many factors, including the cell type, the age of the cell, and the extracellular environment.
A cell that has accumulated a large amount of DNA damage, or one that no longer effectively repairs damage incurred to its DNA, can enter one of three possible states: DNA Replication Animation - Super EASY. DNA Replication Process [3D Animation] Times Higher Education. Punctuated equilibrium. Punctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that once species appear in the fossil record they will become stable, showing little net evolutionary change for most of their geological history.
This state is called stasis. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologically rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another. Punctuated equilibrium is commonly contrasted against phyletic gradualism, the belief that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous.

Lenton_1998.pdf. Gaia. by Brig Klyce. Is it too much to suggest that we may recognize... the beauty and fittingness of an environment created by an assembly of creatures? — James Lovelock (1) Regardless of the paradigm we use to explain it, life on Earth has evolved from bacteria, to single-celled eukaryotic creatures, to multicelled animals and plants, to animals and plants with highly specialized organs and systems. This truth we can all accept. The environment of Earth has also evolved. Earth has cooled, the temperature has stabilized, and the composition of the atmosphere has completely changed. The Oxygen Atmosphere The most important change in Earth's environment since life began is the buildup of free oxygen in the air. Neo-Darwinism: The Current Paradigm. by Brig Klyce. Will mutations produce wings like in angels, in a human being?
If you wanted to develop a race of angels, would it be possible to select for a pair of wings? Neo-Darwinism: The Current Paradigm. by Brig Klyce. Will mutations produce wings like in angels, in a human being? If you wanted to develop a race of angels, would it be possible to select for a pair of wings? Lamarckism. Lamarckism (or Lamarckian inheritance) is the idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring (also known as heritability of acquired characteristics or soft inheritance). It is named after the French biologist Jean-Baptiste Lamarck (1744–1829), who incorporated the action of soft inheritance into his evolutionary theories as a supplement to his concept of an inherent progressive tendency driving organisms continuously towards greater complexity, in parallel but separate lineages with no extinction.
Lamarck did not originate the idea of soft inheritance, which proposes that individual efforts during the lifetime of the organisms were the main mechanism driving species to adaptation, as they supposedly would acquire adaptive changes and pass them on to offspring. History 1880 to 1930 Neo-Darwinism. Neo-Darwinism is the "modern synthesis" of Darwinian evolution through natural selection with Mendelian genetics, the latter being a set of primary tenets specifying that evolution involves the transmission of characteristics from parent to child through the mechanism of genetic transfer, rather than the "blending process" of pre-Mendelian evolutionary science.
Neo-Darwinism can also designate Charles Darwin's ideas of natural selection separated from his hypothesis of Pangenesis as a Lamarckian source of variation involving blending inheritance. From the 1880s to the 1930s, the term continued to be applied to the panselectionist school of thought, which argued that natural selection was the main and perhaps sole cause of all evolution. From then until around 1947, the term was used for the panselectionist followers of R. A. Fisher. Modern evolutionary synthesis See also References External links
The Show-Me Skeptic: A rebuttal to "Dawkins Debunked" by Dr. Norman J Lund PhD. Punctuated equilibrium. Punctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and rapid (on a geologic time scale) events of branching speciation called cladogenesis.
Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another. Punctuated equilibrium is commonly contrasted against the theory of phyletic gradualism, which states that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis).

Naomi Klein: 'Toxic Ideology of Market Fundamentalism' Is to Blame for the 'Degradation of the Planetary System'
Naomi Klein, author of the critically acclaimed book, This Changes Everything: Capitalism vs. the Climate, spoke at the Festival of Dangerous Ideas in Sydney, Australia last weekend. The annual event “brings leading thinkers and culture creators from around the world to the Sydney Opera House stages and online to discuss and debate the important ideas of our time.” Klein’s most recent book argues that the climate crisis cannot be addressed without fundamentally changing our current economic system.
