Although anthropology was the first academic discipline to investigate cultural change, many other disciplines have made noteworthy contributions understanding what influences adoption of new behaviors. Drawing on a broad, interdisciplinary literature covering both humans and nonhumans, we examine ( a) which features behavioral traits make them more transmissible, b) individual characteristics ...

In humans, conventional dendritic cells (cDCs) exist as two unique populations characterized by expression of CD1c and CD141. cDCs arise from increasingly restricted but well-defined bone marrow progenitors that include the common DC progenitor that differentiates into the pre-cDC, which is the direct precursor of cDCs. In this study, we show that pre-cDCs in humans are heterogeneous, consistin...

Species colonizing new environments face an uphill battle to become established. Because colonizing populations are often small, opportunities for sexual reproduction may be limited by availability of mates or viable pollen—an example of an Allee effect (1, 2). The presence of amore abundant related species with similar climatic, habitat, and nutritional needs can further reduce the odds of col...
