DARWIN Y LA IMPOSIBILIDAD DE CAUSAS FINALES EN LA BIOLOGÍA Acta biol.Colomb.
CORRAL CUARTAS,ÁLVARO.
La teoría de la selección natural propuesta por Charles Darwin en su obra El origen de las especies no solo colocó las bases para una explicación coherente de los hechos fundamentales de la biología (el origen común de los seres vivos, la diversidad de individuos y especies y la transmisión de características hereditarias), sino que además introdujo maneras nuevas de hacer filosofía. La teoría de la selección natural hace superflua cualquier posibilidad de apelar a explicaciones de tipo finalista en la ciencia. Desde Aristóteles se conocen cuatro tipos de causa: la material, la formal, la eficiente y la final. Aunque la causa eficiente es el paradigma de explicación por exce-lencia de las ciencias naturales, la causa final sigue desempeñando un papel...

PROBLEMAS ALTRUISTAS DARWINIANOS Acta biol.Colomb.
MARTÍNEZ-CONTRERAS,JORGE.
Darwin propuso en 1871 que preferiría descender de un mono que de los -salvajes-. El mono es un babuino Papio hamadryas que, en un relato de Brehm, salva a un infante de una jauría. Los -salvajes- son los fueguinos a los que visitó en el año 1833. ¿Por qué Darwin, a pesar de haber sido tan buen observador del comportamiento animal, no pudo discernir en qué consistía la sociedad de cazadores-recolectores de los cuatro grupos humanos de Tierra del Fuego? Esto es lo que tratamos de dilucidar en este trabajo.

DARWIN O EL FALSO CONFLICTO ENTRE LA TEORÍA DE LA SELECCIÓN NATURAL Y LA HIPÓTESIS DE LA PANGÉNESIS Acta biol.Colomb.
ANDRADE PEREZ,EUGENIO.
Teniendo como objetivo buscar una compresión más integral de la obra de Darwin, presento una reflexión sobre el desarrollo de sus ideas, resaltando las influencias que la visión mecánica de la naturaleza, el lamarckismo y las teorías recapitulacionistas alemanas, ejercieron sobre él. Se destaca la originalidad de la teoría de la selección natural surgida por comparación con el cruce dirigido y fundamentada en una interpretación de la naturaleza como sistema económico donde se aplica la ley de población de Malthus. Sin embargo, la preocupación de Darwin por el origen de la variación lo llevó a considerar el carácter complejo de este problema y en particular, lo relacionado con la influencia del medio ambiente en la variación evolutiva. En este contexto se...

Establecimiento y Propagación del Darwinismo en Chile: Recepción y Elaboración de las Ideas Gayana
Medel,Rodrigo; Veloso,Alberto.
En este trabajo presentamos un análisis del escenario social y cultural de la época en que ocurre el viaje de Darwin a Chile. Sobre esa base, describimos el impacto a corto y mediano plazo del viaje del naturalista en el ambiente cultural de la época en el país, sugiriendo algunos elementos que pudieron haber infuido en el establecimiento y propagación de las ideas Darwinianas en el Chile de fnes del siglo XIX y primera mitad del siglo XX. Identifcamos tres etapas en el proceso. Primero, una etapa naturalista, relacionada con el aporte directo de Darwin al conocimiento de la diversidad biológica de Chile descrita hasta aquel momento. Segundo, una etapa ideológica, caracterizada por debates no científcos de su obra, los cuales fueron efectuados por...

Charles Darwin, Alfred Russel Wallace, and the Evolution / Creation of the Human Brain And Mind Gayana
Glickman,Stephen E.
Charles Darwin and Alfred Russel Wallace independently discovered natural selection, and a set of common experiences surely contributed to that event. But, there were also major differences in their life-experience as collectors and travelers, their socio-political commitments, and their personal styles. The present paper is focused on, what is, perhaps, the most fundamental area of disagreement between Darwin and Wallace: the evolution of humanity. Darwin argued that human evolution could be explained by natural selection, with sexual selection as a signifcant supplementary principle. Wallace always had doubts about sexual selection, and ultimately concluded that natural selection alone was insuffcient to account for a set of uniquely human...

Charles Darwin’s lost Cinereous Harrier found in the collection of the National Museum of Natural History Leiden Naturalis
Grouw, H. van; Steinheimer, F.D..
During reorganisation of the Leiden bird collection a mounted harrier was found what seemed to be one of the still lost specimens collected by Darwin. After closer research it turned out it was indeed the last missing harrier of the Darwin collection.

Darwin taxonomist: Barnacles and shell burrowing barnacles RChHN
CASTILLA,JUAN CARLOS.
This bibliographic review revisits circumstances in which the wharf, shell burrowing barnacle, Cryptophialus minutus, was first collected by Charles Darwin in southern Chile, in 1836. Further, explores how its collection marked Darwin's taxonomical interest in Cirripedia. A short review analyzes the initial number of extant species of Cirripedia, as described by Darwin and the present situation, with emphasis on recent collections of C. minutus in the southern tip of South America.
Tipo: Journal article Palavras-chave: Chile; Darwin; Dwarf barnacles; Shell burrowing barnacles.

The Darwinian revolution RChHN
CHAVES,ÓSCAR M.
The scientific revolution probably began at 16th century with the heliocentric theory of the eminent astronomer Nicolaus Copernicus, but it was culminated with the masterful discoveries of Galileo Galilei and Isaac Newton at 17th century who revealed that planet movements around the sun and other similar phenomena can be explained by simple mechanical laws of physics and astronomy. However, the origin, complexity and configuration of living beings remained in the mystery until 19th century, with the publication of "On the origin of species". In this essay I discuss the importance of the Darwinian scientific revolution, its beginnings, and the main objections of creationists to his evolutionary ideas. Darwin demonstrated that the origin and complexity of...

Beyond Darwin: On the role of niche construction and self-organization in evolution RChHN
MARQUET,PABLO A.
In this essay I point out to two processes that can potentially complement the classical view of evolution by natural selection as outlined by Darwin, which captures only part of the processes driving adaptive evolution. This classical view should be complemented with sources of order generated within the biological system itself in response to its own structure and dynamics (i.e. self-organization) and by considering the existence of a fundamental circularity in the interaction between the organism and its environment, such that the action of the organisms modify their selective environment thereby affecting their own evolution. The formalization and inclusión of these two processes (and their interaction) represent major challenges and opportunities for...

Emergence of Darwinian theories on evolution of Homo sapiens (Catarrhini: Hominidae) and their relevance for social sciences RChHN
MANRÍQUEZ,GERMÁN.
Despite the great impact that the Darwinian theories on organic evolution have had in the development and consolidation of biology as an autonomous scientific discipline, their relevance in social sciences, and particularly in archaeology and anthropology still remain ambiguous. This ambiguity is reflected in the classical interpretation of Darwin's work pervading Social Sciences during more than one century, according to which the same ideas that contributed to the understanding of natural processes from a scientific perspective would be at the basis of a misleading interpretation of the evolution of human societies due to the application of the principie of natural selection to the social processes. Here we show how the works of T.H. Huxley and A.R....

Darwin, and the role of theories in evolutionary thinking RChHN
MANRÍQUEZ,GERMÁN.
The section "Special Features" is dedicated to share with its readers thematic works about natural history, ecology and evolution. In this introduction we focus on the role that theories play in the construction of evolutionary thinking. First, we briefly show the importance of Lamarck's work in the context of pre-Darwinian theories about organic evolution. Then, the main components of the Darwinian theoretical core and its postDarwinian extensions are thoroughly discussed. Finally the essays following this introduction in the present issue are summarized.
