Overview

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...

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.

The earth is facing a biodiversity crisis. Nearly 50% of animal and plant species could disappear within our lifetime. To stem this rapid loss of biodiversity, we'll need to act quickly — but where should we begin? This news brief, from December 2008, explains how evolutionary history can help us set conservation priorities.
