Studying the communication patterns of scientists can give us insight into how science actually works. We argue that methodological differences between different scientific fields should lead to recognizable differences in how scientists in these fields use language to communicate with one another. This paper reports on a corpus-based study of peer-reviewed journal articles in paleontology and ...
Bermuda is an isolated oceanic island situated 1000 km ESE of Cape Hatteras, North Carolina (Fig. 1, inset). Its volcanic core, last active during the Oligocene (Reynolds & Aumento, 1974), was probably subaerial for some of its existence because rare basaltic pebbles and a small percentage of volcanic grains have been found in surface deposits. Apart from the initial volcanic origin of Bermuda,...
Abstract The concept of evolvability—the capacity a population to produce and maintain evolutionarily relevant variation—has become increasingly prominent in evolutionary biology. Paleontology has long history investigating questions evolvability, but paleontological thinking tended neglect recent discussions, because many tools used the current evolvability literature are challenging apply fos...
The conference 'Celebrating Darwin: From the Origin of Species to Deep Metazoan Phylogeny' was held at the Humboldt University in Berlin, from 3 to 6 March 2009. Specialists from the fields of bioinformatics, molecular biology, developmental biology, comparative morphology and paleontology joined forces to present and discuss novel approaches in reconstructing the still unresolved early branchi...

The origin of living Homo sapiens has once again been the subject of much debate. Genetic data on present human population relationships and data from the Pleistocene fossil hominid record are used to compare two contrasting models for the origin of modern humans. Both genetics and paleontology support a recent African origin for modern humans rather than a long period of multiregional evolutio...
