geoGraph: Connectivity modelling across geographic space with hexagonal discrete global grids

geoGraph models organism movement and connectivity across geographic space using hexagonal grids, improving accuracy over rectangular grids by avoiding distortion.

Cultural norms of exogamy and mobility shape hunter-gatherer genetic evolution

The paper shows that cultural norms and mobility patterns in hunter-gatherer societies influence genetic diversity and reduce homozygosity, preserving fitness.

Pan-African metapopulation model explains Homo sapiens genetic and morphological evolution

The paper models Homo sapiens evolution as a Pan-African metapopulation, showing how climate and connectivity shaped genetic and morphological diversity over 200,000 years.

Human life expectancies are still rising

The paper updates demographic data showing that human lifespans continue to increase globally, supporting Oeppen and Vaupel's original hypothesis over Olshansky's claim of a lifespan ceiling.

Sexual division of labour shapes hunter-gatherer spatial ranges

This study examines gender differences in spatial mobility among Mbendjele BaYaka hunter-gatherers, finding that men's mobility increases with age due to subsistence activities, while women's remains stable, driven by gathering near home.

High-resolution maps of hunter-gatherer social networks reveal human adaptation for cultural exchange

The paper maps social networks of hunter-gatherers to show that non-kin friendships enhance cultural exchange and are an ancestral adaptation.
