Ten Recent Advances in Evolution By Carl Zimmer Posted 10.26.09 NOVA To celebrate the 150th anniversary of the Origin of Species, here's a list—by no means exhaustive—of some of the biggest advances in evolutionary biology over the past decade. These advances include not just a better understanding of how this or that group of species first evolved, but insights into the evolutionary process itself. In some cases those insights would have given Darwin himself a pleasant jolt of surprise. Ten significant leaps forward in evolution research in the past decade, as chosen and described by noted science writer Carl Zimmer Enlarge Photo credit: (Earth) © NASA; (text) © WGBH Educational Foundation Acquired traits can be inherited via small RNAs Columbia University Medical Center (CUMC) researchers have found the first direct evidence that an acquired trait can be inherited without any DNA involvement. The findings suggest that Lamarck, whose theory of evolution was eclipsed by Darwin's, may not have been entirely wrong. The study is slated to appear in the Dec. 9 issue of Cell.

The Evolutionary Psychology of Human Sex and Gender By Daniel Pouzzner, 2000-Apr-11/12 Sexuality is an indispensable mechanism whereby biological evolution bridged the immense gap between asexual/Lamarckian unicellular organisms, and the now plainly preeminent humans. For tens of millions of generations, the lineage leading to humanity has been formed and continued exclusively by sexual procreation. The precise microbiological mechanics of sexuality vary widely from species to species, while the functional consequences - strictly sexual procreation, in which each individual has precisely two parents, each contributing roughly half of the individual's genome - is absolutely conserved. This evidences the overwhelming evolutionary pressure in favor of the sexual mechanism.

educreations teacherswithapps Educreations Interactive Whiteboard, by Educreations, Inc, is an incredible, yes that’s right, INCREDIBLE app. This newly released app comes with the huge bonus of being FREE! We think this app has the edge needed to push education in the right direction and to begin modernizing teaching as we know it. Educreations is not the first app using the whiteboard concept, but it is the first one geared specifically for the classroom. Educreations wants to give teachers the opportunity to create what Sal Khan has been doing for years (read our review of Khan Academy). From gene to function: Genome wide study into new gene functions in the formation of platelets In a study into the genetics of blood cell formation, researchers have identified 68 regions of the genome that affect the size and number of platelets. Platelets are small cells that circulate in the blood and are key to the processes of blood clotting and wound healing. In this genome-wide study, the team used a multidisciplinary approach to successfully identify new genetic variants involved in the formation of platelets and more importantly, defined the function of genes near these variants using a series of biological analyses. Abnormally high or low platelet counts can lead to disease.

Logical Fallacies and How to Spot Them Logical Fallacies and How to Spot Them In the Evolution vs. Creationism debate, it is important to be able to spot all the logical fallacies that Creationists tend to throw around. This essay covers many bare essentials of logical thinking, as well as ways to critically evaluate an argument.
