It is easy for Western-educated scholars to fall into the trap of viewing hunter-gatherer social and sexual arrangements in the light of Western values.[editorializing] One common arrangement is the sexual division of labour, with women doing most of the gathering, while men concentrate on big game hunting. It might be imagined that this arrangement oppresses women, keeping them in the domestic sphere. However, according to some observers, hunter-gatherer women would not understand this interpretation. Since childcare is collective, with every baby having multiple mothers and male carers, the domestic sphere is not atomised or privatised but an empowering place to be.[citation needed] In all hunter-gatherer societies, women appreciate the meat brought back to camp by men. An illustrative account is Megan Biesele's study of the southern African Ju/'hoan, 'Women Like Meat'. Recent archaeological research suggests that the sexual division of labor was the fundamental organisational innovation that gave Homo sapiens the edge over the Neanderthals, allowing our ancestors to migrate from Africa and spread across the globe.
