Hominin geographical range dynamics and relative brain size: Do non-human primates provide a good analogy?

We use climatic and satellite remote sensing data to characterize environmental seasonality in the geographical ranges of extant non-human primates in order to assess the effect of relative brain size on tolerance of more seasonal habitats. Demonstration of such an effect in living non-human primates could provide a comparative framework for modeling hominin dispersals and geographical range dynamics in the Pliocene and Pleistocene. Our analyses found no such effect: there are neither positive nor negative correlations between relative brain size and either geographical range size or the average and range of values for environmental seasonality, whether analysed at the level of all primates, or within parvorders (strepsirrhine, catarrhine, platyrrhine). Independent analyses by other researchers comparing feeding behaviour and ecology at individual primate study sites demonstrate that in seasonal environments, the year-round metabolic costs of maintaining a relatively large brain are met by adaptive behavioural/dietary strategies. However, consistent with our own results, those comparative studies found that there was no overall association, whether positive or negative, between ‘raw' environmental seasonality and primate relative brain size. We must therefore look elsewhere for a comparative model of hominin geographical range dynamics in the Pleistocene.Human Origin

Modeling the evolution of cortico-cerebellar systems in primates

Although it is commonly accepted that brains work as functionally distributed systems in which interconnected structures work together in processing particular types of information, few studies have investigated the evolution of functionally specialized neural systems across many different lineages. MR-related research has provided in-depth information on connectivity patterns, but because of its focus on particular species, it has given only indicative clues about evolutionary patterns shaping brain organization across primates. Here, we combine depth with breadth of analysis by investigating patterns of covarying size evolution in substructures of the cortico-cerebellar system across 19 anthropoid species spanning 35 million years of divergent evolution. Results demonstrate two distinct patterns of size covariation in substructures of the cortico-cerebellar system, suggesting neural systems involving profuse cortico-cerebellar connections are a major factor in explaining the evolution of anthropoid brain organization. We set out an evolutionary model of relative cortico-cerebellar expansion and provide a detailed picture of its branch-specific evolutionary history suggesting the ape radiation is the clade with the strongest and most consistent evolutionary history in relative (frontal) cortico-cerebellar expansion

Three Brain Collections for Comparative Neuroanatomy and Neuroimaging

In the context of increasing extinction rates and the potential loss of essential evolutionary biological and anthropological information, it is an important task to support efforts to prepare, preserve, and curate collections of histological brain sections; to disseminate information on such collections in the neuroscience community; and to make the collections publicly available. This review emphasizes the importance of complete, serially sectioned human brains of different ontogenetic stages as well as those of adult and old human individuals for neurobiological and medical research. Such histological sections enable microstructural analyses and anatomical evaluations of functional and structural neuroimaging data, for example, based on magnetic resonance imaging. Here, this review provides the first detailed and updated account of the content of the Stephan, Zilles, and Zilles-Amunts collections, which consist of serially sectioned and cell body- and myelin-stained histological preparations. Finally, this review will give an overview of past and recent research using these collections to increase our understanding of the detailed patterns of divergent brain evolution in primates as well as of the structural organization of the human brain
