Top 10 Myths About Evolution – with Downloadable PDF | Atheism Resource Email If you have been looking for a simple, easy to follow quick guide to evolution… we’ve got it. Our friends at the Skeptics Society gave us permission to reprint this. Below is the text. Original Text: 1 If Humans Came From Apes, Why Aren’t Apes Evolving Into Humans? Humans, apes, and monkeys are only distant evolutionary “cousins.” 2 There Are Too Many Gaps in the Fossil Record for Evolution to Be True In fact, there are lots of intermediate fossils. 3 If Evolution Happened Gradually Over Millions of Years Why Doesn’t the Fossil Record Show Gradual Change? Sudden changes in the fossil record are not missing evidence of gradualism; they are extant evidence of punctuation. 4 No One Has Ever Seen Evolution Happen Evolution is a historical science confirmed by the fact that so many independent lines of evidence converge to this single conclusion. 5 Science Claims That Evolution Happens by Random Chance Natural selection is not “random” nor does it operate by “chance.”
Scientist: Evolution debate will soon be history NEW YORK (AP) — Richard Leakey predicts skepticism over evolution will soon be history. Not that the avowed atheist has any doubts himself. Sometime in the next 15 to 30 years, the Kenyan-born paleoanthropologist expects scientific discoveries will have accelerated to the point that "even the skeptics can accept it." "If you get to the stage where you can persuade people on the evidence, that it's solid, that we are all African, that color is superficial, that stages of development of culture are all interactive," Leakey says, "then I think we have a chance of a world that will respond better to global challenges." Leakey, a professor at Stony Brook University on Long Island, recently spent several weeks in New York promoting the Turkana Basin Institute in Kenya. The institute, where Leakey spends most of his time, welcomes researchers and scientists from around the world dedicated to unearthing the origins of mankind in an area rich with fossils.

physicscentral Introduction to Evolutionary Biology Introduction to Evolutionary Biology Version 2 Copyright © 1996-1997 by Chris Colby[Last Update: January 7, 1996] volution is the cornerstone of modern biology. It unites all the fields of biology under one theoretical umbrella. It is not a difficult concept, but very few people -- the majority of biologists included -- have a satisfactory grasp of it. Misunderstandings about evolution are damaging to the study of evolution and biology as a whole. This is a brief introduction to evolutionary biology. What is Evolution? Evolution is a change in the gene pool of a population over time. The English moth, Biston betularia, is a frequently cited example of observed evolution. The increase in relative abundance of the dark type was due to natural selection. Populations evolve. Evolution can be divided into microevolution and macroevolution. The word evolution has a variety of meanings. Common Misconceptions about Evolution Evolution is not progress. Genetic Variation Natural Selection
Dispatches from the birth of the Universe: sometimes science gets lucky For the generations that grew up with TV before the age of cable, the box in our living room was a time machine, capable of taking us back to just a few hundred thousand years after the birth of the Universe. We just didn't realize it. Nor did the scientists that discovered this, at least at first. But luck seemed to play a large role in one of the biggest discoveries of our lifetime. That may not have been the intended message of the discussion called "Dispatches from the Birth of the Universe," hosted by the World Science Festival on Friday. The panel provided a good picture of our current state of knowledge on the birth of the Universe, and a glimpse at what we'll likely find out next. Lawrence Krauss, who moderated the panel, introduced it by turning on an old TV set on stage. But, even after the birth of television, nobody realized what it was. But the background they detected from Earth was smooth, while we know the Universe is lumpy, filled with complex structures. And Mather?
6 Insane Discoveries That Science Can't Explain We like to feel superior to the people who lived centuries ago, what with their shitty mud huts and curing colds by drilling a hole in their skulls. But we have to give them credit: They left behind some artifacts that have left the smartest of modern scientists scratching their heads. For instance, you have the following enigmas that we believe were created for no other purpose than to fuck with future generations. The Voynich Manuscript The Mystery: The Voynich manuscript is an ancient book that has thwarted all attempts at deciphering its contents. It appears to be a real language--just one that nobody has seen before. Translation: "...and when you get her to put the tennis racket in her mouth, have her stand in a fountain for a while. There is not even a consensus on who wrote it, or even when it was written. Why Can't They Solve It? Could you? Don't even try. As you can imagine, proposed solutions have been all over the board, from reasonable to completely clownshit. Our Guess:

Evolutionary origins of the nervous system - Neurophilosophy THE human brain is a true marvel of nature. This jelly-like 1.5kg mass inside our skulls, containing hundreds of billions of cells which between them form something like a quadrillion connections, is responsible for our every action, emotion and thought. How did this remarkable and extraordinarily complex structure evolve? This question poses a huge challenge to researchers; brain evolution surely involved thousands of discrete, incremental steps, which occurred in the mists of deep time across hundreds of millions of years, and which we are unlikely to ever fully understand. Nevertheless, a number of studies published in recent years have begun to shed some light on the evolutionary origins of the nervous system, and provide clues to some of the earliest stages in the evolution of the human brain. The simplest nervous systems lack a brain, and instead consist of diffuse networks of nerves. “Such a complex arrangement could not have been invented twice throughout evolution. Related:
THE DARK SITE OF PSYCHIATRY In this page you'll find links to articles and critical documents on biological-psychiatry. Biological-psychiatry's official theory describes psychological or personal problems as having a biological origin caused by genetic or chemical 'imbalances' to be corrected by drugs and other interventions like Electro-Convulsive Therapy [ECT] or insulin shock. These widely used but controversial methods in official medicine have been for many years amply invalidated, showing clearly that they are absolutely unscientific, that they tend to alienate patient's rights, are unable to solve the problems presented, are dangerous for one's health, and are submissive to pharmaceutical companies.
Human evolution Human evolution is the evolutionary process leading up to the appearance of modern humans. While it began with the last common ancestor of all life, the topic usually covers only the evolutionary history of primates, in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of hominids (or "great apes"). The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, ethology, linguistics, evolutionary psychology, embryology and genetics.[1] The earliest documented members of the genus Homo are Homo habilis which evolved around 2.3 million years ago; the earliest species for which there is positive evidence of use of stone tools. The brains of these early hominins were about the same size as that of a chimpanzee, although it has been suggested that this was the time in which the human SRGAP2 gene doubled, producing a more rapid wiring of the frontal cortex. History of study[edit] Before Darwin[edit]
Adaptation | Biology For centuries, human beings have looked at the complexity of the natural world in wonder. From the delicate design of the more than 18,000 species of orchids that exist (Figure 1), to the breathtaking flight of birds, humans have struggled to understand what the driving force behind the diversity of life is and why so many remarkably different shapes and features exist in the natural world. In 1802, the English priest William Paley wrote that the complexity of animals and plants is of "a degree which exceeds all computation," and he argued that only a divine being could have created these organisms. Having been educated in England in the early 19th century, Charles Darwin was not only familiar with Paley's writings, but impressed by them. However, Darwin disagreed with Paley's reasoning. Why would a deity create parasites that would eat away at the insides of an organism, and what would the purpose be of crafting a bird that could not fly?

Solar eclipse of May 20, 2012 Visibility[edit] North America It was the first annular eclipse in the continental U.S. since the solar eclipse of May 10, 1994 which was also the previous eclipse of this series Solar Saros 128. Photo Gallery[edit] Asia Related eclipses[edit] Solar eclipses 2011-2014[edit] Each member in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the moon's orbit. Note: Partial solar eclipses on January 4, 2011, and July 1, 2011, occur in the previous semester series. Saros 128[edit] It is a part of Saros cycle 128, repeating every 18 years, 11 days, containing 73 events. Series members 52-62 occur between 1901 and 2100: Metonic series[edit] The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. This series has 21 eclipse events between May 21, 1993 and May 20, 2069. Notes[edit] References[edit]
