The body weight of AL 288-1 (‘Lucy’): A new approach using estimates of skeletal length and the body mass index

A method of estimating the body mass of hominids by use of the skeletal length and physique index is described. The body mass indices (BMI) of female humans and female chimpanzees are known and this permits an estimate of the probable BMI for the female common ancestor and thus for female morphs intermediate between the common ancestor and modern humans. AL288-1 (‘Lucy’) probably had a BMI of about 22.3 kg m⁻² and for a height of 105cm this yields a body weight estimate of about 25 kg. Body weight estimates of 28–29 kg would imply a body mass index similar to female chimps and are improbable. These conclusions will be compromised if the chimp–gorilla–homo phylogenetic relationship proves to be a trichotomy rather than a chimp–homo dichotomy.     

The Cradle of Thought: Growth,Learning, Play and Attachment in Neanderthal Children

Childhood is a core stage in development, essential in the acquisition of social, practical and cultural skills. However, this area receives limited attention in archaeological debate, especially in early prehistory. We here consider Neanderthal childhood, exploring the experience of Neanderthal children using biological, cultural and social evidence. We conclude that Neanderthal childhood experience was subtly different from that of their modern human counterparts, orientated around a greater focus on social relationships within their group. Neanderthal children, as reflected in the burial record, may have played a particularly significant role in their society, especially in the domain of symbolic expression. A consideration of childhood informs broader debates surrounding the subtle differences between Neanderthals and modern humans.     

Women and microcredit: alternative readings of subjectivity,agency, and gender change in rural Mexico

Within the last two decades, the growth of microcredit, or the provision of small loans to poor borrowers, has become a key development initiative in the Global South. This is particularly important for questions of gender relationships, as the majority of microcredit recipients worldwide are low-income women. However, most assessments of microcredit and gender emphasize issues of individual empowerment rather than the large-scale political implications of credit provision. In this article, I critique the use of mainstream empowerment models employed in the assessment of microcredit's ability to provoke changes in gender relationships. I argue that these models often fail to describe microcredit's effects on women's lives due to their epistemological framework, which pushes aside questions of geographical and historical specificity in pursuit of a universally empowered microcredit subject. Examining a mainstream empowerment model I used to conduct research in rural Mexico, I highlight these problems and present an alternative analysis of subjectivity, agency, and gender change as a result of microcredit provision.
