Many problems in comparative biology and biological anthropology require meaningful definitions of "relative size" and '(shape.'' Here we review the distinguishing features of ratios and residuals and their relationships to other methods of "size-adjustment'' for continuous data. Eleven statistical techniques are evaluated in reference to one broadly interspecific data set (craniometrics of adult Old World monkeys) and one narrowly intraspecific data set (anthropometrics of adult Native American males). Three different types of residuals are compared to three versions of shape ratios, and these are contrasted to '(cscores," Penrose shape, and multivariate adjustments based on the first principal component of the logged variance-covariance matrix; all methods are also compared to raw and logged raw data. In order to help us identify appropriate methods for sizeadjustment, geometrically similar or "isometric" versions of the male vervet and the Inuit male were created by scalar multiplication of all variables. The geometric mean of all variables is used as overall "size" throughout this investigation, but our conclusions would be the same for most other size variables.Residual adjustments failed to correctly identify individuals of the same shape in both samples. Like residuals, cscores are also sample-specific and incorrectly attribute different shape values to individuals known to be identical in shape. Multivariate "residuals" (e.g., discarding the first principal component and Burnaby's method) are plagued by similar problems. If one of the goals of an analysis is to identify individuals (OTUs) of the same shape after accounting for overall size differences, then none of these methods can be recommended. We also reject the assertion that size-adjusted variables should be uncorrelated with size or "size-free"; rather, whether or not shape covaries with size is an important empirical determination in any analysis. Without explicit similarity criteria, "lines of subtraction" can be very misleading.Only variables in the Mosimann family of shape ratios allowed us to identify different sized individuals of the same shape ("iso-OTUs"). Residuals from isometric lines in logarithmic space, projections of logged data onto a plane orthogonal to a n isometric vector, and Penrose shape distance based on logged data are also part of this shape family.

Ground-penetrating radar (GPR) was used to monitor 12 pig burials in Florida, each of which contained a large pig cadaver. Six of the cadavers were buried in sand at a depth of 0.50-0.60 m, and the other six were buried at a depth of 1.00-1.10 m and were in contact with the upper surface of a clay horizon. Control excavations with no pig internment were also constructed as blank graves and monitored with GPR. The burials were monitored with GPR for durations of either 12-13 or 21-21.5 months when they were then excavated to correlate the decomposition state of the cadaver with the GPR imagery. Overall, cadavers in sand were easily detected for the duration of this study at 21.5 months, even when completely skeletonized. Conversely, in clay it became increasingly difficult to image the pig cadavers over the first year of burial, even when they still retained extensive soft tissue structures.

During the past decade or so, considerable new data pertinent to the origin of modern humans have come to light. Based on these new data and reinterpretation of older information, three models have been offered to explain the development of modern people. These models-Brauer's Afro-European sapiens hypothesis, Stringer and Andrew's recent African evolution model, and Wolpoff, Wu, and Thorne's multiregional evolution model-have their roots in earlier models but differ from most by virtue of their worldwide perspective and integration of genetic and paleoanthropological data pertinent to modern human origins. This review presents a detailed discussion of these data in light of the three models. While convincing arguments can be offered for each of these models, it is concluded that none are unequivocally supported by the available data.

Discriminant functions designed for the determination of sex from metacarpal measurements are presented. Three samples of metacarpal specimens were employed in the analysis; one consisting of 212 individuals from the Terry Collection, one of 33 individuals from the Royal Free Medical School in London, and finally, 40 individuals from the Forensic/Donated Collection, Maxwell Museum of Anthropology, University of New Mexico, all of whom had documented sex. Five measurements designed to characterize the size and shape of the human metacarpal were taken on all five digits. Based on the Terry Collection, significant metric differences attributed to race were found for digits I and III, and thus functions could only be derived for the three remaining metacarpals. Sex discriminant functions derived from the Terry Collection for digits II, IV, and V provide correct classification of 92.0, 86.26, and 84.37 percent. The resulting three linear equations were then independently applied to the Royal Free Medical School and Forensic/Donated samples to validate the accuracy of the original functions. Percentage of correct classification for each of the test samples varies.

One of the greatest mysteries for most of the twentieth century was the fate of the Romanov family, the last Russian monarchy. Following the abdication of Tsar Nicholas II, he and his wife, Alexandra, and their five children were eventually exiled to the city of Yekaterinburg. The family, along with four loyal members of their staff, was held captive by members of the Ural Soviet. According to historical reports, in the early morning hours of July 17, 1918 the entire family along with four loyal members of their staff was executed by a firing squad. After a failed attempt to dispose of the remains in an abandoned mine shaft, the bodies were transported to an open field only a few kilometers from the mine shaft. Nine members of the group were buried in one mass grave while two of the children were buried in a separate grave. With the official discovery of the larger mass grave in 1991, and subsequent DNA testing to confirm the identities of the Tsar, the Tsarina, and three of their daughters – doubt persisted that these remains were in fact those of the Romanov family. In the summer of 2007, a group of amateur archeologists discovered a collection of remains from the second grave approximately 70 meters from the larger grave. We report forensic DNA testing on the remains discovered in 2007 using mitochondrial DNA (mtDNA), autosomal STR, and Y- STR testing. Combined with additional DNA testing of material from the 1991 grave, we have virtually irrefutable evidence that the two individuals recovered from the 2007 grave are the two missing children of the Romanov family: the Tsarevich Alexei and one of his sisters.

Identification criteria, specifically discriminant function formulae derived from traditional craniometrics, currently used in South Florida for Cuban Americans and other “Hispanic” groups, are unsuitable to provide adequate biological profiles due to complex biological histories as well as widely diverse geographic origins. Florida's total population is approximately 16 million (15,982,378) individuals. Of the total population 2,682,715, or 16.8%, are self-identified as “Hispanic”. South Florida (herein defined as Miami-Dade, Broward and Collier Counties) is home to 60% of the total Hispanic population of Florida with 1,291,737 (48.15%) residing in Miami-Dade County. The Hispanic population of Miami-Dade County makes up 57.0% of the total population of 2,253,362. Each recognized sub-group of Hispanics (Mexican, Puerto Rican, and Cuban) includes its own geographic point-of-origin and population history. Cuban-Americans (arriving in the late 1950's and early 1960's) make up the largest sub-population of Florida's Hispanics in any county and in Miami-Dade number 650,601 or 51% of the total Latin population. Additionally, as in other agricultural states, Florida has a very large population of undocumented workers who primarily arrive from Texas and points south of the Straits of Florida. Thus the application of the available traditional craniometric and non-metric methods are not appropriate for South Florida's Latin population. To begin to address this issue in relation to South Florida's Cuban population, we present an analysis of cranio-facial shape variation in a 19th Century Cuban sample, 17th Century Spanish sample, a Precontact Cuban sample, and Terry Blacks using geometric morphometric methods. Significant biological shape differences and patterns of variation are observed among the groups. These results provide us with a context in which to begin to understand the biological variation of Cuban Americans, which will enable the development of identification criteria specific for this U.S. hybrid Hispanic community.
