Overview
Este 12 de febrero se cumplirían 200 años del nacimiento de Charles Darwin, y todo el mundo esta invitado a la fiesta. Numerosos grupos alrededor del mundo — desde niños en las escuelas primarias, hasta museos e iglesias — celebraran la ciencia de la evolución con conferencias públicas, clases, obras teatrales, exhibiciones artísticas y muchísimas galletas con forma de tortugas. 'Evolución en las noticias' de este mes contribuye a la celebración mediante la revisión de un tema cercano y querido por Darwin: los pinzones de Galápagos...

Overview
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.

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.

Overview
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.

- Article
Time: 20 minutes
Overview
Diseases like SARS, HIV, and West Nile Virus may be new to humans, but they are old news to other species. These and other emerging infectious diseases have recently added humans to the list of hosts they infect. An evolutionary perspective can help us better understand and, we hope, control this problem.

Overview
Punctuated equilibrium is sometimes erroneously cited as evidence that evolutionary biology still hasn't figured out how evolution works. In fact nothing could be further from the truth. Punctuated equilibrium builds on (not tears down!) established evolutionary theory. Find out how the process works.
