The Extended Evolutionary Synthesis (EES) is beginning to fulfill the whole promise of Darwinian insight through its extension of evolutionary understanding from the biological domain to include cultural information evolution. Several decades of important foundation-laying work took a social Darwinist approach and exhibited ecologically-deterministic elements. This is not the case for more recent developments to the evolutionary study of culture, which emphasize non-Darwinian processes such as self-organization, potentiality, and epigenetic change.


The Archaeology Of The Longue Durée: Temporal And Spatial Scale In The Evolution Of Social Complexity On The Southern Northwest Coast, Kenneth M. Ames Jan 1991

The Archaeology Of The Longue Durée: Temporal And Spatial Scale In The Evolution Of Social Complexity On The Southern Northwest Coast, Kenneth M. Ames

Anthropology Faculty Publications and Presentations

The emphasis on temporal and geographic scale of the French Annales school of history (cf. Braudel 1980; Baker 1984; Lewthwaite 1988) is the inspiration for this paper. Braudel (1980) divides time into three durations: short term events (days, weeks, months, a few years), medium length conjunctures (years, decades, even major portions of centuries), and long term structures (which may last centuries, even millennia). This last duration is the longue durée. Basic to Annales' thought - and the longue durée - is the idea that to understand historical developments, to explain their causes and dynamics, one must know their temporal and their geographic ...


A Multivariate Test Of Evolutionary Stasis In Homo Sapiens, Jon Geoffrey Kleckner Jan 1989

A Multivariate Test Of Evolutionary Stasis In Homo Sapiens, Jon Geoffrey Kleckner

Dissertations and Theses

In the past, efforts to prove or disprove stasis in hominids have relied upon univariate tests such as Students's t-test. Severe methodological and interpretive problems arise from the misapplication of univariate statistics to questions concerning variation in shape through time. These are questions best addressed using the multivariate approach of morphometrics. Eighteen cranial dimensions drawn from 33 mid and late Pleistocene Homo sapiens were examined using principal component analysis (PCA). PCA divided the sample into two distinct morphologies. Archaic Homo sapiens of the mid Pleistocene clustered with Wurm I neanderthals and apart from post Gottweig early anatomically modern Homo ...
