The Gay Animal Kingdom

It appears the classic model of Darwinian sexual selection if way off. Homoesexual behaviour has been identified in up to 450 different animal species yet biologists still consider it outside the norm of "normal" behaviour.
What is Evo Devo?
"Evo Devo". You might have come across this phrase in various articles and comments concerning evolution, but what does it mean? The term is short for evolutionary developmental biology and it is radically changing our views on almost every facet of evolution.
The Gay Animal Kingdom: The Effeminate Sheep & Other Problems with Darwinian Sexual Selection

Joan Roughgarden thinks Charles Darwin made a terrible mistake. Not about natural selection—she's no bible-toting creationist—but about his other great theory of evolution: sexual selection.
How ancient whales lost their legs, got sleek and conquered the oceans
Source: eurekalert.org
More than 50 million years ago the ancestors of whales and dolphins were four-footed land animals, not unlike large dogs. They became the sleek swimmers we recognize today during the next 15 million years, losing their hind limbs in a dramatic example of evolutionary change.
Is evolution predictable? Finding microbes' adaptation algorithms

"Associate professor Yousif Shamoo and two students recently conducted experiments on a microbe, G. stearothermophilus, to see how it adapted to different environmental circumstances.
Forcing Darwin's hand: Capturing natural selection in a flask

Rice University biologists, using an ingenious experiment that forced bacteria to compete in a head-to-head contest for evolutionary dominance, today offer the first glimpse of how individual genetic-level adaptations play out as Darwinian natural selection in large populations.
Choosy females make colourful males

Female fish prefer brightly coloured males because they are easier to see and are in better shape concludes Dutch researcher Martine Maan following her study of fish speciation in the East African Lakes.

From the article -- "The theory of sexual selection -- that females choose males with the best genes, causing those genes to become more prevalent in succeeding generations -- is invoked to explain why peacocks have rococo tails and bucks have huge antlers.
The greenbeards have blue throats in a breakthrough study of the evolution of altruistic behavior
Source: eurekalert.org
A new study of side-blotched lizards in California has revealed the genetic underpinnings of altruistic behavior in this common lizard species, providing new insights into the long-standing puzzle of how cooperation and altruism can evolve.
Molecular variation in one gene affects the growth of natural populations

For the first time, ecologists have been able to show that molecular variation in one gene may affect the growth of a population in its natural habitat.
Natural selection at single gene demonstrated

Chris Toomajian, postdoctoral researcher in molecular and computational biology in the USC College of Letters, Arts and Sciences, led a group that sought to replace the standard neutral model, a common but unrealistic test for natural selection, with a statistical method based on
Creation, Evolution, Human Dignity and Resurrection (addendum to Strict Monotheism Crash Course)
The Holy Scripture asserts that "God created man in His image and likeness" (Gen 1:26-27). This, for the Church, has always been a central statement, because it qualifies in its essence the exclusive dignity that God attributes to man, unique among all creatures.
Why Sex?

A biologist explains the evolutionary advantage of sex, and why we're not all asexual clones.
What is Natural Selection?
Natural Selection. It is a term that is thrown around a lot these days both here on newsvine and in the world at large.
Dickerson’s Rule No.1 : the rule of Science?
In his Darwin's Black Box, Michael J. Behe heavily criticizes (op. cit, Chapter no. 11, section "The Rule", pages 238-243) "methodological naturalism", which he sees epitomized by Richard Dickerson's Rule No. 1

Still Evolving, Human Genes Tell New Story
Source: nytimes.com
Providing the strongest evidence yet that humans are still evolving, researchers have detected some 700 regions of the human genome where genes appear to have been reshaped by natural selection, a principal force of evolution, within the last 5,000 to 15,000 years.
Darwin's Black Box, Vintage Edition
The Free Press (a Division of Simon & Shuster, Inc.) first published Darwin's Black Box in 1996. Now, in March 2006, they have issued a “10th anniversary” new edition. Like a very good quality wine, the book of Professor Michael J.
In Support of Natural Selection

Evolution: Where Darwin meets Lamarck? Discussion Forum
Source: groups.yahoo.com
'Evolution - Where Darwin meets Lamarck?' places an emphasis on concepts and discoveries consistent with the possible existence of testable internal evolutionary mechanisms and alternative (non-creationist) explanations for 'problem areas' of conventional evolutionary theory.
Scientific rhetoric: How creationists reframed the debate.
At first, I found all this talk about intelligent design in the public science classroom infuriating. While I still find it infuriating, I have come to the realization that the debate may actually be a victory for science, after all.
