Observations of evolution


Evo in the news: Warming to evolution
Global warming increasingly affects many aspects of our environment, from the sea level to tropical storm strength. But that's far from the full story. This news brief from July 2006 describes how global warming has already begun to affect the evolution of several species on Earth.

Evo in the news: Musseling in on evolution
This news brief, from September 2006, reviews a recent case of evolution in action. In just 15 years, mussels have evolved in response to an invasive crab species. Find out how biologists uncovered this example of evolution on double time.

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.

15 evolutionary gems
This succinct briefing describes 15 examples drawn from recent research that demonstrate evolutionary theory’s power to explain natural phenomena, along with some of their supporting lines of evidence--from whale fossils to the latest in genetics.
This resource is available from Nature magazine.

Battling bacterial evolution: The work of Carl Bergstrom
This research profile examines how the scientist Carl Bergstrom uses computer modeling to understand and control the evolution of antibiotic resistant bacteria in hospitals.

Interactive investigation: The arthropod story
This interactive investigation delves into the amazing world of the arthropods and examines their success and their evolutionary constraints.

Evo in the news: Speciation in real time
We often think of speciation as a slow process—so slow that we can’t really observe it going on around us. This news brief from Febrary 2010 describes two examples which demonstrate that, at least occasionally, important steps toward speciation can be observed in less than 50 years.

Evolutionary medicine
This excerpted chapter from Carl Zimmer’s book, The Tangled Bank, describes how evolutionary biology informs and advances medical science. Reprinted with the permission of Roberts and Company Publishers, Inc.

Using trees to uproot HIV: The work of Satish Pillai  Advanced
This research profile follows scientist Satish Pillai as he studies the evolution of HIV within infected individuals. His research uses the tools of phylogenetics to investigate vaccine development and the possibility of curing the disease.

Evo in the News: Acidic oceans prompt evolution  Advanced
This news brief, from October 2012, describes new research into the evolutionary response that ocean acidification may prompt in some plankton species.

Evo in the News: Grasshoppers change their tune. Is it evolution in action?  Advanced
This news brief, from December 2012, describes new research into how traffic noise affects insect populations. Several hypotheses to explain the change in grasshoppers' songs are examined.

Especiación en tiempo real
Generalmente, pensamos en la especiación como un proceso lento. Toda la evidencia disponible sostiene la idea de que diferentes especies evolucionaron desde ancestros comunes, y sin embargo, nuevas especies no aparecen a nuestro alrededor diariamente. Para muchos biólogos, esto implica que la especiación ocurre tan lentamente que es difícil observarla en escalas de tiempo humanas. Sin embargo, nuevas investigaciones sugieren que la especiación podria ser más fácil de observar de lo que pensamos.
