In this contribution I will review the development of ideas about a recent African origin for our species over the last 50 years, starting from the time of my PhD in the early 1970s. I will examine the instructive and quite different interpretations placed on the 1979 discovery of a partial Neanderthal skeleton associated with a Châtelperronian industry at the rock shelter of St-Césaire in France, and then focus on the crucial years from 1987-1989, including the so-called 'Human Revolution' conference of 1987, and my 1988 Science paper with Peter Andrews: 'Genetic and Fossil Evidence for the Origin of Modern Humans'. Following the historical review, I will assess the status of five proposed models for the evolution of derived Homo sapiens: Recent African Origin (RAO); RAO and Hybridisation (RAOH); Assimilation (AM); Multiregional Evolution (MRE); and Braided Stream (BS). I conclude that a recent African origin model with hybridization (RAOH) is the best supported from the fossil and genetic evidence.

Mounting evidence points to the importance of fermented fruits in the diets of tropical frugivores, especially African apes. But how has this fundamental aspect of ape ecology escaped scientific attention over the past six decades? Here we draw inspiration from the Middle Ages to fill an essential void in scientific discourse.

Background: The National Health and Nutrition Examination Survey provides nationally representative data on child obesity using measured height and weight. Due to COVID-19, the NHANES August 2021-August 2023 cycle had design changes and smaller sample sizes for certain race/Hispanic origin groups. The objective is to explore sex and race/Hispanic origin-specific childhood obesity trends.

Adaptive management has long been advocated as a framework of choice for addressing the complexities and uncertainties of natural resource management. Despite its theoretical appeal, successful implementation remains elusive, with many documented barriers and limited operational examples. This paper examines Strategic Adaptive Management (SAM), a long-running adaptive management program originating from the Kruger National Park in South Africa.

We report cases of infections on the scalp of three individuals from an African family, originating from Mali and residing in Guangzhou. This is the first time that has been reported in China. The index case involved a 2-year-old boy who presented with scalp patches and scaling for more than 1 year.
