St. George Jackson Mivart
St. George Jackson Mivart is mostly remembered as a cautionary tale. If Mivart is mentioned at all in modern debates, it is to offer an example of how not to do biology and theology. However, in this paper I argue that, ongoing developments in evolutionary biology have produced genuine alternatives to strict neo-Darwinism that not only seek to downplay the role of natural selection, but do so in ways that are strikingly reminiscent of Mivart’s un…
Preclassic Obsidian Procurement and Utilization at the Maya Site of Colha, Belize
This study explores the early use of obsidian at the Maya site of Colha in northern Belize and the implications that variations in source distribution have for the site and its regional connections. Energy dispersive x-ray fluorescence (EDXRF) analysis of 104 specimens of obsidian from Preclassic contexts at the site identified El Chayal obsidian as the most common overall followed closely by that from San Martin Jilotepeque. Ixtepeque obsidian, …
Setting the Stage
The relationship between culture and environment and the effects of variable climatic conditions on past cultures have long been recognized, but have not always been pursued in archaeological investigations. Early studies treated the environment as a static phenomenon, partly due to lack of precise dating methods and underdevelopment in the science of paleoclimatology. This paper outlines the history of paleoclimatic/paleoenvironmental reconstruc…
Late Holocene Climates of North-Central Texas
Recent investigations at a multicomponent archaeological site (41DL270) along Denton Creek in Denton and Dallas Counties, Texas, yielded a series of mussel shell features which were sampled for isotopic variation in oxygen and carbon. Oxygen values showed a marked trend which may indicate that δ18O can be used as a reliable paleoclimatic indicator in small riverine drainage systems such as Denton Creek. The δ13C values exhibited high variability …
Expanding the Role of Trace-Element Studies
The results of trace-element analysis of 200 prismatic blades from Colha, Belize, are reported. Questions concerning possible elite control and restriction of obsidian distribution, and the relative decline and increase of the El Chayal and Ixtepeque sources in varying functional contexts within lower- and upper-status areas are the primary focus of the study. Contrary to expectations, a high percentage (51%) of obsidian was assigned to the Ixtep…
The Berger Bluff Site (41GD30A)
During summer 1979, the Center for Archaeological Research conducted excavations at the Berger Bluff site (41 GO 30A) in Goliad County, Texas. The site, located on a high bluff above Coleto Creek, had been shown to be a valuable archaeological resource in previous test excavations and was potentially endangered by wave erosion from the waters of the soon to be completed Coleto Creek Reservoir. The excavations were considered necessary as a partia…
