Book Section Reprint the STRUGGLE for TROGLODYTES1
The RELICT HOMINOID INQUIRY 6:33-170 (2017) Book Section Reprint THE STRUGGLE FOR TROGLODYTES1 Boris Porshnev "I have no doubt that some fact may appear fantastic and incredible to many of my readers. For example, did anyone believe in the existence of Ethiopians before seeing any? Isn't anything seen for the first time astounding? How many things are thought possible only after they have been achieved?" (Pliny, Natural History of Animals, Vol. VII, 1) INTRODUCTION BERNARD HEUVELMANS Doctor in Zoological Sciences How did I come to study animals, and from the study of animals known to science, how did I go on to that of still undiscovered animals, and finally, more specifically to that of unknown humans? It's a long story. For me, everything started a long time ago, so long ago that I couldn't say exactly when. Of course it happened gradually. Actually – I have said this often – one is born a zoologist, one does not become one. However, for the discipline to which I finally ended up fully devoting myself, it's different: one becomes a cryptozoologist. Let's specify right now that while Cryptozoology is, etymologically, "the science of hidden animals", it is in practice the study and research of animal species whose existence, for lack of a specimen or of sufficient anatomical fragments, has not been officially recognized. I should clarify what I mean when I say "one is born a zoologist. Such a congenital vocation would imply some genetic process, such as that which leads to a lineage of musicians or mathematicians. -

A New Vision of the Senses in the Work of Galileo Galilei
Perception, 2008, volume 37, pages 1312 ^ 1340 doi:10.1068/p6011 Galileo's eye: A new vision of the senses in the work of Galileo Galilei Marco Piccolino Dipartimento di Biologia, Universita© di Ferrara, I 44100 Ferrara, Italy; e-mail: [email protected] Nicholas J Wade University of Dundee, Dundee DD1 4HN, Scotland, UK Received 4 December 2007 Abstract. Reflections on the senses, and particularly on vision, permeate the writings of Galileo Galilei, one of the main protagonists of the scientific revolution. This aspect of his work has received scant attention by historians, in spite of its importance for his achievements in astron- omy, and also for the significance in the innovative scientific methodology he fostered. Galileo's vision pursued a different path from the main stream of the then contemporary studies in the field; these were concerned with the dioptrics and anatomy of the eye, as elaborated mainly by Johannes Kepler and Christoph Scheiner. Galileo was more concerned with the phenomenology rather than with the mechanisms of the visual process. His general interest in the senses was psychological and philosophical; it reflected the fallacies and limits of the senses and the ways in which scientific knowledge of the world could be gathered from potentially deceptive appearances. Galileo's innovative conception of the relation between the senses and external reality contrasted with the classical tradition dominated by Aristotle; it paved the way for the modern understanding of sensory processing, culminating two centuries later in Johannes Mu« ller's elaboration of the doctrine of specific nerve energies and in Helmholtz's general theory of perception. -
Evolution of Tbe Mandibular Appendage in Figwasps (Hymenoptera: Agaonidae)
Rev. Biol. Trop., 39 (1): 87-95. 1991 Evolution of tbe mandibular appendage in figwasps (Hymenoptera: Agaonidae) William Ramírez B. Escuela de Fitotecnia, Universidadde Costa Rica. (Ree. 20-IX-I990. Acep. 15-X-I990) Abstract: The phylogenetic value of the conformation of the mandibular appendages, the number of mandibular glands andother head characters in the Agaonidae are examined.The phylogenetic arrangement suggests thatthe pre agaonid had a normal bidentate mandible with two glands, and a undistinct facial groove as in sorneDiazi ella (Sycoecinae), Sycophaga (Sycophaginae) and in related chalcidoid non-pollinating fig wasps. lt also had thirteen-seg mented antennae;'a long scape, several times ¡onger than wide a long triangular pedicel, two or three anelli andeight flagellomeres withsensilla (as uniquely found in Tetrapus). The mandibularappendage apparently co-evolved with the development oí the ostiolum of thesyconium andthe firstmandibular appendage was fixed andhad ridges or lameUae. A flexible hinge evolved laterat its base.The polygamous males were wingless with extendible (solenogastrus) abdo men and mate inside the galls. These characters are also found in most Sycophaginae.The ancestor of Aganoidae was probably a primary sycophilous wasp, withdorsoventral depressed head, thorax and abdomen, that oviposit through thestylar channel as stiU Sycophaga sycomori does. Sycophaga wasps withits apterousand polyg amous males seem to be the sister group of Agaonidae. The Agaonidae females are characterized by their mandibular appendage and the antennalprocess. They have a prognathous head with gula. Themales are wingless polygamous andsolenogastrous. Key words: Agaonidae(Hymenoptera), mandibular appendage, evolution, phylogeny. Ficus is pollinated by small chalcidoid wasps and two or three antennal anelli. -

San Rafael Atlixco 186, Col. Vicentina, Mexico 09340 D.F. (Received February 20, 2007, Accepted June 17, 2007) Abstract The interaction between figs (Ficus spp., Moraceae) and fig-pollinating wasps (Chalcidoidea, Agaonidae) is one of the most species-specific cases of mutualism, and is a model system for studying coevolution and cospeciation between insects and plants. To test the specificity-breakdown hypothesis, we performed a phylogenetic analysis using mitochondrial COi gene sequences of Mexican fig-pollinating wasps collected from each fig species at various localities. Phylogenetic analysis revealed a clear division of Mexican fig pollinators into two major groups: one pollinating the Ficus species of subgenus Pharmacosycea: and the other pollinating Ficus subgenus Urostigma. -
The Boy with Two Heads Free
FREE THE BOY WITH TWO HEADS PDF Andy Mulligan | 400 pages | 01 Oct 2015 | Random House Children's Publishers UK | 9780552573474 | English | London, United Kingdom The Boy With Two Heads by Andy Mulligan He was writing of the Boy of Bengal after observing drawings The Boy with Two Heads collecting and reviewing the accounts of several of his peers. While the boy was remarkable for both his medical condition and perseverance, Home was actually incorrect in his initial assumptions. His remarkable life was very nearly extinguished immediately after his delivery as a terrified midwife tried to destroy the infant by throwing him into a fire. Miraculously, while he was rather badly burned about the eye, ear and upper head, he managed to survive. His parents began to exhibit him in Calcutta, where he attracted a great deal of The Boy with Two Heads and earned the family a fair amount of money. While the large crowds gathered to see the Two-Headed Boy The Boy with Two Heads parents took to covering the lad with a sheet and often kept him hidden — sometimes for hours at a time The Boy with Two Heads often in darkness. As his fame spread across India, so did the caliber of his observers. Several noblemen, civil servants and city officials arranged to showcase the boy in their own homes for both private gatherings and grand galas — treating their guests to up close examinations. When compared to the average child, both heads were of an appropriate size and development. The The Boy with Two Heads head sat atop the main head inverted and simply ended in a neck-like stump. -
Galileo in Early Modern Denmark, 1600-1650
1 Galileo in early modern Denmark, 1600-1650 Helge Kragh Abstract: The scientific revolution in the first half of the seventeenth century, pioneered by figures such as Harvey, Galileo, Gassendi, Kepler and Descartes, was disseminated to the northernmost countries in Europe with considerable delay. In this essay I examine how and when Galileo’s new ideas in physics and astronomy became known in Denmark, and I compare the reception with the one in Sweden. It turns out that Galileo was almost exclusively known for his sensational use of the telescope to unravel the secrets of the heavens, meaning that he was predominantly seen as an astronomical innovator and advocate of the Copernican world system. Danish astronomy at the time was however based on Tycho Brahe’s view of the universe and therefore hostile to Copernican and, by implication, Galilean cosmology. Although Galileo’s telescope attracted much attention, it took about thirty years until a Danish astronomer actually used the instrument for observations. By the 1640s Galileo was generally admired for his astronomical discoveries, but no one in Denmark drew the consequence that the dogma of the central Earth, a fundamental feature of the Tychonian world picture, was therefore incorrect. 1. Introduction In the early 1940s the Swedish scholar Henrik Sandblad (1912-1992), later a professor of history of science and ideas at the University of Gothenburg, published a series of works in which he examined in detail the reception of Copernicanism in Sweden [Sandblad 1943; Sandblad 1944-1945]. Apart from a later summary account [Sandblad 1972], this investigation was published in Swedish and hence not accessible to most readers outside Scandinavia. -

Los gemelos monocigóticos, compartirán o no las membranas fetales dependiendo del momento en el que tiene lugar la división del embrión, siendo bicoriales biamnióticos, monocoriales biamnióticos o monocoriales monoamnióticos. Cuando la división del embrión sucede a partir del día trece, se forman los gemelos siameses, unidos por alguna parte de su cuerpo, y en algunos casos existen gemelos parasitarios, desarrollándose uno de los fetos sólo parcialmente y quedando unido al cuerpo de su co-gemelo. El embarazo múltiple conlleva un mayor riesgo de complicaciones fetales, maternas y perinatales, que las gestaciones unifetales. Siendo más frecuente el aborto, el retraso del crecimiento intrauterino y otras malformaciones congénitas. En los gemelos monocoriónicos diamnióticos cabe destacar el síndrome de transfusión entre gemelos TTTS ( Twin-To-Twin Transfusion syndrome), siendo su grado máximo la denominada Secuencia TRAP ( Twin-reversed arterial perfusion sequence). -

Weiblen University of Minnesota, Department of Plant Biology, St. Paul, Minnesota 55108; e-mail: [email protected] Key Words Agaonidae, coevolution, cospeciation, parasitism, pollination ■ Abstract In the two decades since Janzen described how to be a fig, more than 200 papers have appeared on fig wasps (Agaonidae) and their host plants (Ficus spp., Moraceae). Fig pollination is now widely regarded as a model system for the study of coevolved mutualism, and earlier reviews have focused on the evolution of resource conflicts between pollinating fig wasps, their hosts, and their parasites. Fig wasps have also been a focus of research on sex ratio evolution, the evolution of virulence, coevolu- tion, population genetics, host-parasitoid interactions, community ecology, historical biogeography, and conservation biology. This new synthesis of fig wasp research at- tempts to integrate recent contributions with the older literature and to promote research on diverse topics ranging from behavioral ecology to molecular evolution.

Introduction
Introduction 1Aristotle Accordingtothe Oxford English Dictionary (online version), in contemporary English usagethe word ‘nutrition’ carries four meanings: 1. The action or process of supplying,orofreceiving,nourishment or food. 2. That which nourishes; food,nourishment. 3. The state or condition of being (well or badly) nourished;aperson’sstate of health considered as aresultorindicator of (good or bad) nourishment. 4. The branch of science that deals with nutrition (sense 1)and nutrients, esp. in humans;the studyoffood and diet. In light of the abovedefinitions, ‘nutrition’ seems an appropriate English render- ing for the Greek words τροφή or τὸ τρέφειν/τρέφεσθαι,which are used by au- thors of the 5th and 4th centuries BCE to refer to processes, activities or functions related to nourishment,oreventokinds of food or nutriment that are able to nourish or procuresustenance. The term θρέψις is not attested before the 2nd cen- tury CE. In Galen θρέψις is acknowledgedasone of the three main activities (ἐνέργειαι)ofnature – the othertwo being growth and generation (De facultati- bus naturalibus I,5, K. II,10). Specifically, rendering 4resonates with what in Hippocratic texts is some- times referredtoasdietetics, that is, that part of the medicalart (and not science) which dealswith diet (δίαιτα). The gradual development of dietetics into acor- nerstone of medicine wasset off by medical ideas of that time which are closely akin to rendering3,most notablythe belief that aperson’sstate of health de- pends heavilyonthe food (s)he consumes.Inone of its two main meanings (the other being ‘rearing’, ‘bringingup’), τὸ τρέφειν,apart from the act of nour- ishing,refers to the substances thatare able to nourish (so, rendering 2).Now concerning nutrition as abodilyfunctionrelated to aset of individual physiolog- ical activities of certain bodyparts, Aristotle seems to deserve, at least to acer- tain degree, credit for being the first to explicitlymake such aprogress (cf. -
Galileo E Liceti, Ovvero Genio E Mediocrità
LA COSCIENZA: TRA FILOSOFIA E NEUROSCIENZE 239 GALILEO E LICETI, OVVERO GENIO E MEDIOCRITÀ MARIAPIERA MARENZANA già Docente di Lettere presso l’Accademia Nazionale di Danza, Roma 1. Fortunio Liceti Fortunio Liceti, chi era costui? Era, proprio come il Carneade di manzoniana memoria, un filosofo aristotelico, il quale tuttavia, a differenza dell’antico Carneade, ebbe la ventura di essere contemporaneo di Galileo e suo corrispondente. A questo egli deve, assai più che alla vasta cultura libresca e alla iperprolifica attività di scrittore, l’aver consegnato il suo nome alla storia. Emerge infatti, dalla trentennale corrispondenza tra i due, oltre al ritratto a tutto tondo di due personalità tanto diverse, un quadro vivace dei rapporti conflittuali e drammatici fra la cultura tradizionale fondata su «un mondo di carta» e quella nuova, basata sull’esperimento e sul dubbio. C’è inoltre molto Liceti ritratto nel Simplicio del Dialogo, e anche nel più rispettabile Simplicio dei Discorsi, ed è da una polemica con Liceti che ha origine l’ultima opera scientifica di Galileo. Sullo sfondo dell’epistolario sono le vicende biografiche dei due corrispondenti, i principali allievi dello scienziato pisano, le dispute accademiche, i contatti culturali in Italia e in Europa, l’ombra minacciosa dell’Inquisizione, la peste, ma anche aspetti minuti della vita quotidiana del ‘600. Liceti deve il suo nome, Fortunio, alla nascita prematura e avventurosa avvenuta, nel 1577, su una nave sbattuta da una tempesta nel tratto di mare fra Recco e Rapallo; il padre, medico, avrebbe assicurato la sopravvivenza del bimbo ponendolo in una scatola tenuta in caldo. Il fortunoso ingresso nel mondo, e i racconti che certamente gliene vennero fatti, influirono senza dubbio sul gusto per il meraviglioso e l’insolito che avrebbe caratterizzato la vita di Liceti.
