Abstract: Fossil hominin taxonomy is still debated, chiefly due to the fragmentary nature of fossils and the use of qualitative (subjective) morphological traits. A quantitative analysis of a complete database of hominin cranial capacities (CC, n=207) and body weight estimates (Wt, n=285), covering a period from 5.1 ma (millions of years) to 10 ka (thousands of years) shows no discontinuities through time or geographic latitude. Distributions of residuals of CC and Wt around regressions on date and latitude are continuous and do not differ significantly from normal. Thus, with respect to these characteristics, all hominins appear to be a single gradually evolving lineage.
