Notes from the archives
Margaret Floy Washburn was one of the leading psychologists of her generation, whose most important work was The Animal Mind (Goodman, 1980). As E. G. Boring noted, that text "reflected her own love of animals and her intense interest in their behavior" (1971, p. 547). What about the role of animals in Washburn's personal life?

Giving it a burl
In this paper we outline a worked example of the combined use of genetic data and archaeological evidence. The project focuses on Queensland's Cape York Peninsula and has two goals. One is to shed new light on the population \nhistory of the region. The other is to develop a methodology to facilitate \nrepatriation of the remains of Aboriginal Australians. After providing some \nbackground to the project and outlining its main activities, we summ…
An investigation of sequence deletions of amelogenin (Amely), a Y-chromosome locus commonly used for gender determination
Comparisons of both deletion size and haplotypes with published data suggest that most AMELY nulls are the result of independent evolutionary events, even in those populations where the frequency is relatively high. Although AMELY null males are extremely rare in most populations, typing an additional gender-determining locus should be considered in forensic investigations where the reference sample is of unknown gender
Genetic diversity within a caste population of India as measured by Y‐chromosome haplogroups and haplotypes
The extent of population subdivision based on 15 Y‐chromosome polymorphisms was studied in seven subcastes of the Golla (Karnam, Pokanati, Erra, Doddi, Punugu, Puja, and Kurava), who inhabit the Chittoor district of southern Andhra Pradesh, India. These Golla subcastes are traditionally pastoralists, culturally homogeneous and endogamous. DNA samples from 146 Golla males were scored for seven unique event polymorphisms (UEPs) and eight microsatel…
Haplotype Study of Intermediate-Length Alleles at the Fragile X (FMR1) Gene
The CGG repeat within the X-chromosome-linked FMR1 gene, which in hyperexpansion (> 200 copies) results in fragile X syndrome, is highly polymorphic. The mechanism of expansion is not well understood, but CGG repeats called intermediate-length or gray zone alleles (approximately equal 35-60 repeats) are thought to make up the FMR1 alleles showing initial steps in this expansion process. It has been hypothesized that the background haplotype of th…
Genetic Structure and Gene Flow in Gran Chaco Populations of Argentina
The Gran Chaco region of central South America has been settled by humans for only the last 4,000-5,000 years. To investigate population structure and variation in this region's indigenous population, we scored males from tribes of the Argentinean part of the Gran Chaco (Pilagá, Wichí, and Toba, representing two major language groups, the Mataco and Guaycurú) for a number of Y-chromosome polymorphisms. The markers included eight microsatellites (…
Alleles and Haplotypes of Tumor Necrosis Factor (TNF) Alpha and Beta Genes in Three Ethnic Populations of Sulawesi, Indonesia
Polymorphic variation in two cytokine genes, tumor necrosis factor (TNF) -alpha and -beta, was examined in three ethnic groups, the Bugis, the Makassans, and the Torajans, who inhabit Sulawesi, a large island in the Indonesian archipelago, and formerly a Dutch colony. TNF-alpha and -beta are key molecules in immune responses to infection, and both have been implicated in the pathogenesis and clinical manifestations of parasitic diseases. Several …
Y-Chromosomal Diversity in Europe Is Clinal and Influenced Primarily by Geography, Rather than by Language
Red-green colour blindness in the Isle of Man and Cumbria
The frequencies of red-green colour-blind males in the indigenous population of two regions of Britain, the Isle of Man (5.6 per cent) and Cumbria (5.0 per cent), do not readily fit into the pattern of a SW-NE gradient in the frequency of the colour-blind gene in Britain suggested by earlier studies. Frequencies of red-green colour-blind females are also given for these two populations
