Francisco Javier Muñiz. Cirujano de guerra / Francisco Javier Muñiz. War Surgeon

Francisco Javier Muñiz nació en Monte Grande en 1795 y se graduó de médico en la Facultad de Medicina de la Universidad de Buenos Aires en 1822. Además de la medicina y la paleontología, Muñiz se desempeñó como cirujano de guerra en la guerra con el Brasil y en la guerra de la Triple Alianza. En 1871, encontrándose jubilado, se ofrece como voluntario en la lucha contra la epidemia de fiebre amarilla que asoló a la ciudad de Buenos Aires provocando 14.467 muertos. Muñiz falleció el 8 de abril de 1871 en cumplimiento del deber, contagiado de fiebre amarilla. Médico, periodista, paleontólogo, descubridor de la vacuna nativa contra la viruela y realizador de apuntes de lingüística, Francisco Javier Muñiz, representa uno de los grandes ejemplos para la sociedad argentina.

Francisco Javier Muñiz was born in Monte Grande in 1795 and graduated as a physician from the Faculty of Medicine of the University of Buenos Aires in 1822. In addition to medicine and paleontology, Muñiz served as a military surgeon in the War with Brazil and in the War of the Triple Alliance. In 1871, when he was retired, he volunteered to fight the yellow fever epidemic that devastated the city of Buenos Aires, causing 14,467 deaths. Muñiz died in the line of duty on April 8, 1871, infected with yellow fever. Doctor, journalist, paleontologist, discoverer of the native vaccine against smallpox and linguistic note-taker, Francisco Javier Muñiz is one of the great examples for Argentinian society. (AU)

Series of forms, visual techniques, and quantitative devices: ordering the world between the end of the nineteenth and early twentieth centuries.

In this paper, I investigate the variety and richness of the taxonomical practices between the end of the nineteenth and the early twentieth centuries. During these decades, zoologists and paleontologists came up with different quantitative practices in order to classify their data in line with the new biological principles introduced by Charles Darwin. Specifically, I will investigate Florentino Ameghino's mathematization of mammalian dentition and the quantitative practices and visualizations of several German-speaking paleontologists at the beginning of the twentieth century. In so doing, this paper will call attention to the visual and quantitative language of early twentieth-century systematics. My analysis will therefore contribute to a prehistory of the statistical frame of mind in biology, a study which has yet to be written in full. Second, my work highlights the productive intertwinement between biological practices and philosophical frameworks at the turn of the nineteenth century. Deeply rooted in Kantian bio-philosophy, several biologists sought to find rules in order to apply ordering principles to chaotic taxonomic information. This implies the necessity to investigate the neglected role of Kantian and Romantic bio-philosophy in the unfolding of twentieth-century biology.

Manifest ambiguity: Intermediate forms, variation, and mammal paleontology in Argentina, 1830-1880.

This paper presents the impact of diverse aspects of Darwin's works on the practices of mammal paleontology in different moments of nineteenth-century Argentina. Starting with Darwin through the publications of Florentino Ameghino, it shows the extraordinary complexity of systematic paleontology that characterized the second half of the nineteenth century. Neither "natural selection" nor "struggle for life" seemed to have shaped the practices of vertebrate paleontology in Argentina. Darwin's earlier work as a voyageur and geologist together with later concerns about intermediate forms and variation allow for an assessment of the impact of Darwin's work on the practice of paleontology in Argentina.

A nação pela pedra: coleções de paleontologia no Brasil, 1836-1844 / Petrifying the nation: paleontology collections in Brazil, 1836-1844

A formação e o estudo de coleções de história natural e de paleontologia participaram da instauração da ordem política do Império do Brasil, delineando também uma ordem científica. A simbiose entre ciência e nação encontrou em Peter W. Lund, iniciador dos estudos de paleontologia em nosso país, um agente ativo e constante. As coleções e escritos desse naturalista deram amparo à visualização do passado e à escrita da história em museus, instituições científicas e culturais brasileiras e europeias. As disputas pelo ordenamento político sob as Regências e a Maioridade foram acompanhadas de perto pelo estudo e a explicação das formas de vida e do globo no passado.

The formation and study of natural history and paleontology collections was part of the installation of political order under the Empire of Brazil, as well as the establishment of a scientific program. The symbiosis between science and the nation was actively promoted by Peter W. Lund, pioneer of paleontology studies in the country. The collections and writings produced by the naturalist lent support to the visualization of the past and the writing of history in Brazilian and European scientific and cultural institutions and museums. The disputes over the political order under the Regencies and the Majority were closely accompanied by the study and explanation of the forms of life and the planet found in the past.

John Tweedie and Charles Darwin in Buenos Aires.

The journey of exploration undertaken by Charles Darwin FRS during the voyage of HMS Beagle has a central place within the historical development of evolutionary theory and has been intensively studied. Despite this, new facts continue to emerge about some of the details of Darwin's activities. Drawing on recently published Darwin material and unpublished letters in the archives of the Royal Botanic Gardens, Kew, we document a hitherto unexamined link between Darwin and John Tweedie (1775-1862), a relatively obscure Scottish gardener turned South American plant collector. All of the available evidence points to a meeting between the two men in Buenos Aires in 1832. Tweedie provided Darwin with information about the geography of the Rio Paraná, including the locality of fossilized wood eroding from the river bank. It also seems likely that Tweedie supplied Darwin with seeds that he later shipped back to John Stevens Henslow in Cambridge. Although this brief meeting was at the time relatively unimportant to either man, echoes of that encounter have resonated with Tweedie's descendants to the present day and have formed the basis for a family story about a written correspondence between Darwin and Tweedie. Local information supplied to Darwin by residents such as Tweedie was clearly important and deserves further attention.

Lazzaro Spallanzani e os fósseis: das observações em viagens naturalísticas ao ensino de história natural / Lazzaro Spallanzani and fossils: from a naturalist's travel observations to the teaching of natural history

Analisa opiniões do naturalista italiano Lazzaro Spallanzani sobre a origem e a constituição dos fósseis por ocasião de três de suas viagens naturalísticas, entremeadas a três cursos de mineralogia da disciplina de história natural que lecionou na Universidade de Pavia. Essas viagens, para Portovenere, ilha Cerigo e Duas Sicílias, permitiram que abordasse temas importantes, como a descoberta de conchas fósseis no interior de rochas vulcânicas, a de fósseis humanos, e a existência de fósseis de espécies que 'se perderam', incorporando conhecimentos que se desenvolviam na época, com base na química mineralógica. Sua preocupação com os fósseis testemunha o modo como, ao estilo do século XVIII, Spallanzani integrava os estudos dos três reinos da natureza.

This article analyzes opinions expressed by Italian naturalist Lazzaro Spallanzani on the origin and constitution of fossils on three of his travels, which punctuated three courses in mineralogy he gave in the natural history discipline at the University of Pavia. These trips to Portovenere, the island of Cerigo and the Two Sicilies enabled him to address important topics, such as the discovery of fossilized shells inside volcanic rocks, the discovery of human fossils, and the existence of fossils of species that had 'been lost', incorporating knowledge being developed at the time that drew on mineral chemistry. His concern with fossils is demonstrative of how Spallanzani, in true eighteenth century fashion, integrated studies from the three kingdoms of nature.

Geographic patterns of craniofacial variation in pre-Hispanic populations from the Southern Cone of South America.

In this study we analyzed the relationships and patterns of spatial variation from morphological cranial variability of 17 population samples representing the ancient inhabitants of the central territory of Argentina (archaeologically known as "Sierras Centrales") and other pre-Hispanic populations from different ecological and geographic regions of the Southern Cone of South America (Argentina and Uruguay), based on the analysis of 10 craniofacial measurements. Results obtained from D2 distances can be interpreted as evidence of a similar biological history for the populations that inhabited the Sierras Centrales and the population of Santiago del Estero. Matrix correlation analysis demonstrated that craniometric variation is significantly influenced by geography, suggesting that populations that lived at lower geographical distance share more biological similarity. Global spatial autocorrelation analysis suggests a clinal pattern for the biological variation, although Moran's I estimates calculated for each variable demonstrate that only nasal height and breadth show this spatial pattern of variation. Results from spatial regression techniques show a significant effect of altitude modeling nasal shape, in agreement with previous studies suggesting that nasal morphology is strongly influenced by environment variables.

Francisco Javier Muñiz: el primer investigador argentino / Francisco Javier Muñiz: the first argentinean researcher

Lo polifacético de su personalidad hace que comencemos su biografíade una forma poco convencional. El interés por los estudios paleontológicos en nuestro país se remonta al siglo XVIII, aunque la persistencia en la búsqueda y una verdadera arista científica tienen como precursora Francisco Javier Muñiz. Las primeras indagaciones paleontológicasde Muñiz tienen lugar alrededorde la laguna de Chascomús. Allí encontró restos de un gliptodonte y de un armadillo (Dasypus giganteus), descubrimientos que no comunicó a ninguna entidad científica y por esto perdióla paternidad del hallazgo. Muñiz nació el 21 de diciembre de1795 en Monte Grande, provincia de Buenos Aires. Se recibió de médico en 1822 y en 1824 presentó su tesisde doctorado. En 1828 contrajo matrimonio con Ramona Bastarte y fue nombrado médico de policía y administradorde vacuna en el pueblo de Luján. (AU)

Resíduos alimentares, infecções parasitárias e evidência do uso de plantas medicinais em grupos pré-históricos das Américas / Food waste, parasitic infections and evidence of the use of medicinal plants in groups of prehistoric Americas

A paleoparasitologia utiliza como principal instrumento de estudo a análise de coprólitos e sedimentos retirados do solo de sítios arqueológicos, latrinas e da área pélvica de esqueletos. Associando-se dados da arqueologia, antropologia e paleoparasitologia, entre outras ciências, é possível obter resultados consistentes sobre modo de vida e saúde das populações no passado. Neste trabalho foram analisadas amostras de três regiões diferentes das Américas. Um total de 59 amostras de coprólitos e sedimentos provenientes de sítios arqueológicos localizados na área arqueológica de São Raimundo Nonato, que engloba o Parque Nacional Serra da Capivara (PNSC), Piauí, Brasil, foram analisadas. Esta região apresenta sítios com datações bastante antigas obtidas na área do Parque, com evidência de atividades humanas datadas aproximadamente de 50.000 anos; 12 amostras provenientes do sítio arqueológico Antelope Cave, localizado no Arizona, EUA. Assim como o PNSC, este sítio possui a presença de cerâmica e a iniciação da agricultura pelos grupos pré-históricos naquela região; e 15 amostras retiradas diretamente da região pélvica de sepultamentos provenientes do sambaqui Cubatão I, localizado em Joinville, Santa Catarina, Brasil. Este sítio arqueológico é, na verdade, um desafio metodológico devido ao clima e a atividade biótica do solo da região que não permitem boas condições de preservação do material arqueológico. A análise de resíduos alimentares destas diferentes regiões arqueológicas forneceu dados a respeito da dieta de populações antigas e a relação entre a presença de parasitos e o encontro de plantas com propriedades anti-helmínticas, e ainda foi possível a determinação de casos de falso parasitismo.

Paleoparasitology uses, as the main tool to study, the analysis of coprolites andsediments removed from the land of archaeological sites, latrines and the pelvic area of skeletons. Joining data from archeology, anthropology and paleoparasitology, among other sciences, it is possible to obtain solid results on livelihoods and health of people in the past. On this study were analyzed samples from three different regions of the Americas. A total of 59 samples of coprolites and sediments from archaeological sites located in thearchaeological area of São Raimundo Nonato, which includes the National Park Serra da Capivara (PNSC), located in Pernambuco, Brazil, were analyzed. This region has sites with the oldest dating obtained in the Park, with human activities recorded from 50.000 years BP; 12 samples from the archaeological site of Antelope Cave, located in Arizona, USA. This site, just like PNSC, has features such as the presence of pottery and the initiation of agriculture by prehistoric groups in the region, and 15 samples taken directly from the pelvic region of burials from the sambaqui Cubatão I, located in Joinville, Santa Catarina, Brazil. This archaeological site is actually a methodological challenge due to the climate and soil biotic activity in the region that don't allow good conditions of preservation of the archeological material. The analysis of alimentary residues of these different archaeological areas supplied dataregarding the diet of old populations and the relationship between the presence ofparasites and the encounter of plants with anthelminthic properties, and it was still possible the determination of cases of false parasitism.

'Cenas de tempos profundos': ossos, viagens, memórias nas culturas da natureza no Brasil / 'Scenes from deep times': bones, travels, and memories in the cultures of nature in Brazil

Este artigo considera os diferentes papéis assumidos pelos naturalistas de campo e de gabinete na construção das culturas da natureza e na disputa para a construção de carreiras científicas no século XIX. A partir do conceito de 'experiência liminar', comenta aspectos ainda pouco considerados da obra paleontológica de Peter Wilhelm Lund (1801-1880) no Brasil e sua repercussão internacional.

This article examines the different roles played by field and non-field naturalists in constructing cultures of nature and in the dispute to construct scientific careers in the nineteenth century. Based on the concept of "threshold experience," it looks at little-explored aspects of Peter Wilhelm Lund's paleontological work (1801-1980) in Brazil and its international impact.
