Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)
The Anatomical Record, EarlyView.Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

The Anatomical Record, EarlyView.Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.

The malagarasi river does not form an absolute barrier to chimpanzee movement in Western Tanzania. [PDF]
PLoS ONE, 2013 The Malagarasi River has long been thought to be a barrier to chimpanzee movements in western Tanzania. This potential geographic boundary could affect chimpanzee ranging behavior, population connectivity and pathogen transmission, and thus has ...

Learning to rank using privileged information [PDF]
, 2013 Many computer vision problems have an asymmetric distribution of information between training and test time. In this work, we study the case where we are given additional information about the training data, which however will not be available at test ...

The bonobo genome compared with the chimpanzee and human genomes
Nature, 2012 Two African apes are the closest living relatives of humans: the chimpanzee (Pan troglodytes) and the bonobo (Pan paniscus). Although they are similar in many respects, bonobos and chimpanzees differ strikingly in key social and sexual behaviours, and ...

Alu recombination-mediated structural deletions in the chimpanzee genome. [PDF]
PLoS Genetics, 2007 With more than 1.2 million copies, Alu elements are one of the most important sources of structural variation in primate genomes. Here, we compare the chimpanzee and human genomes to determine the extent of Alu recombination-mediated deletion (ARMD) in ...

Biological Reviews, EarlyView.ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Biological Reviews, EarlyView.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Human-specific transcriptional regulation of CNS development genes by FOXP2. [PDF]
, 2009 The signalling pathways controlling both the evolution and development of language in the human brain remain unknown. So far, the transcription factor FOXP2 (forkhead box P2) is the only gene implicated in Mendelian forms of human speech and language ...
