Danko Brncic y la coadaptación RChHN
ROTHHAMMER,FRANCISCO; MANRÍQUEZ,GERMÁN.
El concepto de coadaptación es antiguo en biología. <A HREF="#DARWIN">Darwin (1859)</A> se refiere a la "gran cantidad de complejas e indispensables coadaptaciones estructurales existentes entre un ser orgánico y otro". El concepto también fue utilizado por <A HREF="#DOBZHANSKY37">Dobzhansky (1937)</A>, por <A HREF="#MATHER43">Mather (1943)</A> y por <A HREF="#MATHER49">Mather &amp; Harrison (1949)</A>. Cuando Brncic llegó a Nueva York a trabajar al laboratorio de Dobzhansky, la coadaptación era ampliamente aceptada como mecanismo de mantención de variación genética en poblaciones y formaba parte del modelo balancista cuyo máximo exponente era precisamente este genetista. A comienzos de la década de 1950...

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.
