La evo-devo como ciencia histórica de causas remotas
(Universidad Nacional de Colombia, Facultad de Ciencias, Departamento de Biología, 2009)
ABSTRACT EVO-DEVO AS HISTORICAL SCIENCE OF ULTIMATES CAUSES Having as starting point that a proximal cause is one which effects can be registered in the states of an individual organism, in this work I will argue that what ...
Nós primatas em linguagem: relações lingüísticas como um processo biológico
(Universidade Federal de Minas GeraisUFMG, 2006-06-08)
The aim of the present thesis is to approach linguistic phenomena as biological processes, through the proposition of a descriptive model based on four conceptual operations: 1) to consider the organism as a system of ...
Evolutionary Insights from Bat Trypanosomes: Morphological, Developmental and Phylogenetic Evidence of a New Species, Trypanosoma (Schizotrypanum) erneyi sp nov., in African Bats Closely Related to Trypanosoma (Schizotrypanum) cruzi and Allied Species
(ELSEVIER GMBH, URBAN & FISCHER VERLAGJENA, 2012)
Parasites of the genus Trypanosoma are common in bats and those of the subgenus Schizotrypanum are restricted to bats throughout the world, with the exception of Trypanosoma (Schizotrypanum) cruzi that also infects other ...
Pectoral girdle and forelimb variation in extant Crocodylia: the coracoid–humerus pair as an evolutionary module
(Wiley Blackwell Publishing, Inc, 2013)
To date, all statements about evolutionary morphological transformation in Crocodylia have essentially been based on qualitative observations. In the present study, we assessed the morphological variation and covariation ...
Developmental and genetic constraints on neurocranial globularity: Insights from analyses of deformed skulls and quantitative genetics
(Springer, 2009-03)
Neurocranial globularity is one of the few derived traits defining anatomically modern humans. Variations in this trait derive from multiple and complex interactions between portions of the brain and the size and shape of ...
Morphological changes in the seminal receptacle during ovarian development in the speckled swimming crab Arenaeus cribrarius
(2014-08-01)
To understand sperm plug dissolution and spermatophore dehiscence in Portunidae, histological and ultrastructural changes in the seminal receptacle (SR) of Arenaeus cribrarius were investigated during ovarian development. ...

(Universidad Nacional de QuilmesUniversidad Nacional de Tres de Febrero, 2014-10-01)
El concepto marxiano de fetichismo de la mercancía es susceptible de aplicación en biología evolutiva para revelar muchas imprecisiones contenidas en las concepciones neodarwinistas y parte de su carácter ideológico. Postulo ...
Towards the resolution of a long-standing evolutionary question: muscle identity and attachments are mainly related to topological position and not to primordium or homeotic identity of digits
(Wiley, 2015-04)
Signaling for limb bone development usually precedes that for muscle development, such that cartilage is generally present before muscle formation. It remains obscure, however, if: (i) tetrapods share a general, predictable ...
