|
 | 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: Evolving altitude aptitude
This news brief from October 2010 examines new research that makes it clear that Tibetan highlanders have not just acclimated to their mountain home; evolutionary adaptations have equipped them with unique physiological mechanisms for dealing with low oxygen levels.

|
 | Evo in the news: Genetic variation helps rescue endangered panthers
In the 1990s, scientists predicted that the Florida panther would be extinct within 20 years and, in 1995, formulated a bold plan to save them. This news brief of December 2010 reports on the success of that plan which gave the panther a second lease on life by the infusion of genetic variation.

 | Angling for evolutionary answers: The work of David O. Conover
Human activity has certainly affected our physical environment - but it is also changing the course of evolution. This research profile follows scientist David O. Conover as he investigates the impact of our fishing practices on fish evolution and discovers what happened to the big ones that got away.

|
 | The genes that lie beneath: The work of Leslea Hlusko
Evolutionary biologist Leslea Hlusko’s research takes her from the deserts of Ethiopia, where she hunts for hominid and primate fossils, to a baboon colony in San Antonio where she takes thousands of measurements of the primates' imposing canines. This research profile describes how the two projects are linked by a hunt for genetic variation, a key component of natural selection.

 | 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.
|
|
 | 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.

 | Evolution connection: Proteins, carbohydrates, and nucleic acids
This short slide set weaves basic information about carbohydrates, proteins, and nucleic acids into one evolutionary story regarding the evolution of lactose tolerance, which relates to students’ everyday lives. Save the slide set to your computer to view the explanation and notes that go along with each slide.

 | Fire ants invade and evolve
Understanding the evolution of fire ants may help scientists control the spread of these pests, which have already taken over much of the U.S.

|
 | Webcast: Selection in action
In lecture two of a four part series, evolutionary biologist David Kingsley discusses how just a few small genetic changes can have a big effect on morphology, using examples from maize, dog breeding, and stickleback fish.
This lecture is available from Howard Hughes' BioInteractive website.

 | Inducing Evolution in Bean Beetles
In this lab, students design and conduct experiments to evaluate whether evolution by natural selection (or alternatively, genetic drift) may be induced in laboratory populations.

|
 | The Making of the Fittest: The Birth and Death of Genes
This 13-minute film describes how scientists have pieced together the evolutionary history of the Antarctic icefish by studying its genome – an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.

 | Sexo, especiación y física subacuática
Evolución en las noticias relata una reciente historia que señala como comprender física básica puede revelar como la evolución esta ocurriendo hoy — en especial, como la física de la luz tiene influencia sobre la selección sexual, especiación y el colapso de la biodiversidad, producto de la polución causada por los humanos...

 | Mejores biocombustibles gracias a la evolución
Actualmente, la mayoría de nosotros llenamos nuestro tanque de gasolina con combustibles fósiles, es decir, restos de plantas y animales que murieron muchos millones de años atrás y eventualmente se convirtieron en petróleo — pero, por supuesto, esto no puede perdurar para siempre. El petróleo es un recurso limitado y en algún momento se va a terminar. Para ayudar a solucionar este problema, muchos científicos, políticos, gente de negocios y ciudadanos preocupados han puesto sus esperanzas en los biocombustibles...

 | Las chinches de cama pican de nuevo gracias a la evolución
Las chinches de cama puede parecer un viejo problema pasado de moda, sin embargo ahora están de vuelta — y con venganza. Hace cincuenta años, estas plagas chupadoras de sangre estaban casi erradicadas en los Estados Unidos gracias, en parte, al uso de pesticidas como el DDT. Hoy, se arrastran entre las sabanas — y atormentan a los desgraciados soñadores — en todo el país...
