¿De donde vienen todas las especies de Madagascar?
Continuando la celebración del tema de Octubre en el Año de la Ciencia, las ciencias de la tierra y el planeta Tierra, la historia de este mes se centra en cómo la geografía y la geología han moldeado la evolución de la vida en uno de los lugares más singulares de la Tierra. Madagascar, la cuarta isla más grande del mundo, se encuentra en el Océano Índico a varios cientos de kilómetros de la costa sureste de África y constituye el hogar de una notable variedad de especies vegetales y animales, incluido el aye aye, la fossa, el camaleón y el árbol baobab...

A look at linguistic evolution
We typically think of evolution occurring within populations of organisms. But in fact, evolutionary concepts can be applied even beyond the biological world. Any system that has variation, differential reproduction, and some form of inheritance will evolve if given enough time. Find out how an understanding of evolution can illuminate the field of linguistics.

Biological warfare and the coevolutionary arms race
The rough-skinned newt looks harmless enough but is, in fact, packed full of one of the most potent neurotoxins known to man. Find out how an evolutionary arms race has pushed these mild-mannered critters to the extremes of toxicity and how evolutionary biologists have unraveled their fascinating story.

Bringing homologies into focus
There's more to homologies and analogies than the iconic examples (e.g., the tetrapod limb) found in every high school textbook. This article goes beyond the basics to explore the many evolutionary scenarios that result in homoplasies and the many levels at which homologies might occur.

Cells within cells: An extraordinary claim with extraordinary evidence
When biologist Lynn Margulis revived the strange-sounding idea that the merging of cells played a prominent role in the evolution of complex life, the scientific community roundly rejected the notion. Today, this idea is accepted as a textbook fact. Learn more about the evidence and social factors that spurred the acceptance of this key aspect of evolutionary theory.
This article is available from the Understanding Science website.

DNA and mutations
Mutations are the ultimate source of genetic variation and are therefore, essential to evolution. Learn more about the causes, effects, and types of mutations, as well as their role in evolution.

Evo in the news: Gender-biased bacteria throw off an evolutionary balance
The percentage of southwestern whiteflies infected with Rickettsia bacteria has skyrocketed; but this is not a boon for local farmers, as the bacterium actively helps the pest spread. This news brief examines how evolutionary theory accounts for this and how we might turn it in our favor.

Evo in the news: Genealogy enthusiasts mine DNA for clues to evolutionary history
This news brief, from November 2007, turns an evolutionary lens on businesses that use DNA for genealogy research and, in the process, illuminates what their genetic tests really track.

Evo in the news: Got lactase?
The ability to digest milk is a recent evolutionary innovation that has spread through some human populations. This news brief from April 2007 describes how evolution has allowed different human populations to take advantage of the nutritional possibilities of dairying and links evolution with the prevalence of lactose tolerance among people of different ethnicities.

Evo in the News: Grasshoppers change their tune. Is it evolution in action?

Evo in the news: Making sense of ancient hominin DNA
In March 2010 German researchers announced that they had managed to extract DNA from the 40,000 year old fossil bone from a child discovered in a Siberian cave and that it didn't match up to the known genetic sequences of either humans or Neanderthals! This news brief examines the evidence in more detail and considers what that evidence might — or might not — mean about such claims.

Evo in the news: One small fossil, one giant step for polar bear evolution
This news brief from April 2010 describes what scientists have learned by extracting DNA from a polar bear fossil more than 100,000 years old. Though the fossil itself was just a fragment of the skeleton—the lower left portion of the jaw, still containing a tooth—the DNA had a lot to say about polar bear evolution.

Evo in the news: Seeing the tree for the twigs
Recent research has revealed that, in at least some ways, chimpanzees have evolved more than humans have. This news brief from May 2007 delves into this finding further and, in the process, debunks common misperceptions of human evolution.

Evo in the news: Sex, speciation, and fishy physics
More than 500 species of cichlid fish inhabit Africa's Lake Victoria. This news brief from March 2009 explains new research suggesting that the physics of light may have played an important role in cichlid diversification and in the recent drop in their diversity.

Evo in the News: What comes after mass extinctions?
This news brief, from September 2012, describes the aftermath of mass extinctions--what happens to surviving species in the wake of a massive extinction event.

Evo in the News: When fighting leukemia, evolutionary history matters
This news brief, from December 2011, describes how evolutionary history can factor into the success of a bone marrow transplant.

Evo in the news: Where did all of Madagascar's species come from?
Recently, political unrest in Madagascar has threatened to set back the island’s expanding conservation efforts, and criminals have taken advantage of the instability, looting protected forests for rare wood. This news story from October 2009 turns back the clock to consider the biogeographic processes that made Madagascar into a biodiversity hotspot in the first place.

Understanding the process of development can help us understand how some major evolutionary changes occurred and why others did not.

Why the eye?
Eyes are something of an icon of evolution. How did such an integrated, multi-part adaptation evolve? While many different animals have complex eyes, untangling their evolutionary history reveals both remarkable diversity and surprising similarity.
