| During a visit to the Rijksmuseum van Natuurlijke Historie in Leiden in July 1964, Dr D. A. Hooijer kindly allowed me to re-examine the mandibular fragment which had been discovered by Eugène Dubois on 24 November 1890 at Kedung Brubus, a fossil locality in the Kendeng Beds in Central Java (Dubois, 1891a, 1891b, 1924a, 1924b). As a result of a possibly important new point which emerged during my examination of the specimen, Dr Hooijer urged me to place my observations and their implications on record. It is the purpose of this short paper to do so. BRIEF HISTORICAL SYNOPSIS In his original two notes of 1891, Dubois clearly recognized the fragment as belonging to "Homo spec. indet." He drew attention to the poor chin development and the curious flattening... |

| The Amazonian rainforest is arguably the most species-rich terrestrial ecosystem in the world, yet the timing of the origin and volutionary causes of this diversity are a matter of debate. We review the geologic and phylogenetic evidence from Amazonia and compare it with uplift records from the Andes. This uplift and its effect on regional climate fundamentally changed the Amazonian landscape by reconfiguring drainage patterns and creating a vast influx of sediments into the basin. On this “Andean” substrate, a region-wide edaphic mosaic developed that became extremely rich in species, particularly in Western Amazonia. We show that Andean uplift was crucial for the evolution of Amazonian landscapes and ecosystems, and that current biodiversity patterns... |

| We characterized evolutionary patterns of host plant use across about 2500 species of British Lepidoptera, using character optimization and independent phylogenetic contrasts among 95 operational taxa, and evaluated the extent to which caterpillars are monophagous, use woody host plants, and feed concealed. We also analyzed the use of different Angiosperm superorders and related these associations to other key variables. The Nepticulidae, Pterophoridae, and Gracillariidae allowed explicit comparisons between the British fauna and the Lepidoptera worldwide, which indicated that our broad categorizations for Britain are accurate predictors for the global fauna. The first (lower glossatan) radiation of the Lepidoptera started with monophagous, internal... |

| Left-right asymmetry patterns in the body shapes of animals and plants have been a continuous source of interest among biologists. Recently, inroads have been made to developing a coherent research programme that makes use of the unique fact that chiral patterns may be studied (and generalities deduced) by comparisons across many unrelated groups, even across Kingdoms. The papers delivered at the symposium ‘Evolution of Chirality’ during the 2011 European congress of evolutionary biology (ESEB) provide examples of the various research programs that are currently developing within this field. The present paper provides a summary of the symposium, an introduction to this Special Issue of Contributions to Zoology, as well as suggestions for further... |

| The nearly neutral theory of molecular evolution predicts that small population size is essential for non-adaptive evolution. Evolution of whole-body left-right reversal in snails is generally a compelling example of non-adaptive speciation, because variants with reversed chirality would suffer from reduced mating opportunities within a population. Despite this reproductive disadvantage, sinistral snail species have repeatedly originated from dextral ancestors in terrestrial pulmonates. Here I show that snail speciation by reversal has been accelerated on oceanic islands. Analysing the global biogeography of 995 genera across 84 stylommatophoran families, I found that the proportion of sinistral snail genera was enhanced in genera endemic to oceanic... |

| Absolute (Linnaean) ranks are essential to rank-based nomenclature (RN), which has been used by the vast majority of systematists for the last 150 years. They are widely recognized as being subjective among taxonomists, but not necessarily in other fields. For this reason, phylogenetic nomenclature (PN) and other alternative nomenclatural systems have been developed. However, reluctance to accept alternative nomenclatural systems and continued use of higher taxa of a given Linnaean category in comparative analyses presumably reflect a lack of appreciation of the deleterious effects of the subjective nature of Linnaean categories in other biological fields, such as conservation and evolutionary biology. To make that point clearer, evolutionary models under... |
