The National Academies In the News: Your Inner Fish – A Scientific Adventure Have you ever wondered why people look the way they do? Why our hands and feet have five digits instead of six? Why we stand on two legs instead of four? It took 350 million years of evolution to produce the amazing machine we call the human body and in Your Inner Fish, a three-part series based on the best-selling book of the same name, author and evolutionary biologist Dr. Neil Shubin looks into the past to answer these and other questions. Follow that adventure now on PBS Darwin's Insights Continue to Inspire the Academy's Work The ideas of Charles Darwin and the concept of evolution by natural selection continue to have a profound influence on modern biology – they permeate almost every area of scientific exploration. In 2010, the National Academy of Sciences awarded its most prestigious award, the Public Welfare Medal, to Dr.
Teaching materials Teaching materials Evolution is essential to our curriculum and to scientific literacy. Imagine teaching social science without teaching history; students would lack perspective on events going on today. Similarly, to understand the big picture of biology, students need to understand life on Earth in terms of its history and its future — the changing life forms and ecosystems that have arisen and changed over billions of years, as well as the mechanisms that have brought about those changes. The Understanding Evolution project aims to help instructors develop student understanding of: We've assembled a variety of resources to help you increase student understanding of evolution.
La Evolución Biológica La Evolución Biológica En 1543 (y no se impacienten con la fecha), Nicolás Copérnico publicó "De revolutionibus orbium caelestium", libro en el que propuso un nuevo y revolucionario sistema del mundo sobre la base de una Tierra en movimiento. En 1859, más de tres siglos más tarde, otro hombre revolucionario publicó "Sobre el origen de las Especies", en donde también se vertían nuevas y radicales ideas sobre la naturaleza de la vida. El título de esta página no es más que una alusión (espero que no presuntuosa) a esta semejanza, porque si bien separados por varios siglos, ambos personajes fueron prácticamente tratados de herejes y ambos han sido los artífices de sendas revoluciones científicas y del pensamiento humano. El primer genoma eucariota secuenciado fue el de la levadura de la cerveza Saccharomyces cerevisiae, un eucariota unicelular, en 1997. Sigo con mi ambición inicial: divulgar lo que constituye una de las ramas más apasionantes de la Ciencia.
Water is dangerous This was found on the newsgroup: rec.humor.funny A student at Eagle Rock Junior High won first prize at the Greater Idaho Falls Science Fair, April 26. He was attempting to show how conditioned we have become to alarmists practicing junk science and spreading fear of everything in our environment. In his project he urged people to sign a petition demanding strict control or total elimination of the chemical "dihydrogen monoxide." And for plenty of good reasons, since: it can cause excessive sweating and vomiting it is a major component in acid rain it can cause severe burns in its gaseous state accidental inhalation can kill you it contributes to erosion it decreases effectiveness of automobile brakes it has been found in tumors of terminal cancer patients He asked 50 people if they supported a ban of the chemical. He feels the conclusion is obvious.
The Panda's Thumb Teaching of Evolution in Schools - NSTA Position Statements Introduction The National Science Teachers Association (NSTA) strongly supports the position that evolution is a major unifying concept in science and should be emphasized in K–12 science education frameworks and curricula. Furthermore, if evolution is not taught, students will not achieve the level of scientific literacy needed to be well-informed citizens and prepared for college and STEM careers. NSTA recognizes that a century of political controversy has prevented evolution from being emphasized in science curricula in a manner commensurate with its importance. Declarations Within this context, NSTA recommends that Science curricula, state science standards, and teachers should emphasize evolution in a manner commensurate with its importance as a unifying concept in science and its overall explanatory power. NSTA offers the following background information: The Nature of Science and Scientific Theories Science is a method of testing natural explanations for natural objects and events.

Edwards v. Aguillard [This is the text of the 1987 United States Supreme Court decision striking down a Louisiana law that required if evolution is taught in public schools then creationism must also be taught. This 7-2 decision ended any prospect of public schools in the United States being legally forced to teach explicate creationism. One consequence of this case was that some antievolutionists choose to use the term "intelligent design" instead of "creationism."] The Supreme Court affirmed the judgment of the court of appeals, which in turn had affirmed the District Court's decision finding the Louisiana act unconstitutional. The decision had Brennan, Marshall, Blackmun, Powell, Stevens, O'Connor, and White on the majority, with Scalia and Rehnquist dissenting. Held Opinion Majority Opinion by Brennan I, II, III (A)(B), IV, V Concurring Opinion by Powell I (A), (B), II, III Concurring Opinion by White Dissenting Opinion by Scalia I, II, (A) (B), III EDWARDS, GOVERNOR OF LOUISIANA, ET AL. v.

Teaching Evolution This summary was compiled by Karin Kirk, SERC, and is drawn from the sources referenced below. View looking northeast from the Yavapai Observation Station on the South Rim of Grand Canyon National Park. Few topics engage the multifaceted challenges of the affective domain as much as evolution does. From the faculty point of view, teachers may be frustrated by judicial, political and social pressures against the teaching of evolution that seem poised to undermine the science. Meanwhile students may be faced with the difficult decision to "believe" in the science or to maintain their faith in another interpretation. There is no shortage of information written about the teaching of evolution. Understand and be respectful of where the students are coming from. Examples from Across the SERC Website General References This list is not intended to present a comprehensive list of evolution resources.

Evolution in Action: Lizard Moving From Eggs to Live Birth Evolution has been caught in the act, according to scientists who are decoding how a species of Australian lizard is abandoning egg-laying in favor of live birth. Along the warm coastal lowlands of New South Wales (map), the yellow-bellied three-toed skink lays eggs to reproduce. But individuals of the same species living in the state's higher, colder mountains are almost all giving birth to live young. Only two other modern reptiles—another skink species and a European lizard—use both types of reproduction. Evolutionary records shows that nearly a hundred reptile lineages have independently made the transition from egg-laying to live birth in the past, and today about 20 percent of all living snakes and lizards give birth to live young only. But modern reptiles that have live young provide only a single snapshot on a long evolutionary time line, said study co-author James Stewart, a biologist at East Tennessee State University.
