 Behavioural ecologists working in Bolivia have found that wild spider monkeys control their diets in a similar way to humans, contrary to what has been thought up to now. Rather than trying to maximize their daily energy intake, the monkeys tightly regulate their daily protein intake, so that it stays at the same level regardless of seasonal variation in the availability of different foods. |

 Morphometric and phylogenetic analyses of the fossilised remains of the jaws and teeth of a shrew discovered in a deposit in Gran Dolina de Atapuerca, in Burgos, have shown this to be a new species (Dolinasorex glyphodon) that has not previously been described. The extinct animal had red teeth, was large in size compared with mammals of the same family, and was more closely related to Asian than European shrews. |

Aggressive, vengeful behavior of individuals in some South American groups has been considered the means for men to obtain more wives and more children, but an international team of anthropologists working in Ecuador among the Waorani show that sometimes the macho guy does not do better. |

 African, American, and European researchers working in collaboration over a 10-year period have released the largest-ever study of African genetic data—more than four million genotypes—providing a library of new information on the continent which is thought to be the source of the oldest settlements of modern humans. |

 The Lost World, Sir Arthur Conan Doyle's account of an isolated community of dinosaurs that survived the catastrophic extinction event 65 million years ago, has no less appeal now than it did when it was written a century ago. Various Hollywood versions have tried to recreate the lost world of dinosaurs, but today the fiction seems just a little closer to reality. |

 The bombardment of Earth nearly 4 billion years ago by asteroids as large as Kansas would not have had the firepower to extinguish potential early life on the planet and may even have given it a boost, says a new University of Colorado at Boulder study. |

 Neandertals, the 'stupid' cousins of modern humans were capable of capturing the most impressive animals. This indicates that Neandertals were anything but dim. Dutch researcher Gerrit Dusseldorp analysed their daily forays for food to gain insights into the complex behaviour of the Neandertal. His analysis revealed that the hunting was very knowledge intensive. |

 The analysis of a termite entombed for 100 million years in an ancient piece of amber has revealed the oldest example of "mutualism" ever discovered between an animal and microorganism, and also shows the unusual biology that helped make this one of the most successful, although frequently despised insect groups in the world. |

 A detailed analysis of the feet of Homo floresiensis—the miniature hominins who lived on a remote island in eastern Indonesia until 18,000 years ago—may help settle a question hotly debated among paleontologists: how similar was this population to modern humans? |

 The Neoproterozoic interval of "hidden" evolution refers to a gap of unknown duration between the time when animals first evolved (uncertain) and the oldest known fossil or geochemical evidence of animals (latest Neoproterozoic, about 600-650 million years ago). |

 A study with participation of the Spanish Scientific Research Council (CSIC) identified between 129 and 221 new species of frogs from Madagascar, which practically doubles the currently known amphibian fauna. This study, published in the journal Proceedings of the National Academy of Sciences of the USA, suggests that the number of amphibian species in Madagascar, one of the world’s biodiversity hotspots, has been significantly underestimated. According to the researchers, if these results are extrapolated at a global scale, the number of amphibian species worldwide could double. |

 A group of scientists at The Scripps Research Institute has set up the microscopic equivalent of the Galapagos Islands—an artificial ecosystem inside a test tube where molecules evolve to exploit distinct ecological niches, similar to the finches that Charles Darwin famously described in "The Origin of Species" 150 years ago. |
