This room preserves the atmosphere of the first decades of the journey of El Museo Canario. The exhibition on it of the large collection of skulls possessed by the institution is intended to draw attention to a particular fact: from the late nineteenth century until well-advanced the twentieth century an important part of the research around the pre-Hispanic past of the islands was focused on the metric and morphological analysis of the bone remains – especially skulls – of the Aboriginal population , in order to develop a typological classification. Thus, a distinction was made between two large groups – a population of chromatinoid features and a population of mediterranean features – in which two waves of population were intended and to which differentiated cultural manifestations were associated. This led to a biological explanation of Aboriginal society, which remained in force until not many decades ago, desponsing knowledge of the ways of life of the ancient canaries.
