The authors should be more circumspect in reporting their results, acknowledging that the stature estimates from modern humans are likely exaggerations, and focus their interpretations on the more appropriate (but still tenuous) australopithecine - based predictions — still with the caveat about the limitations of the data from which the predictor is derived.

The identification of large - size individuals among the australopithecines — i.e. hominins commonly presumed to be small - bodied on average — shows also that the available fossil record can be misleading, resulting in an underestimate of the hominin phenotypic diversity in any given period.

In order to contextualise the australopithecine and early Homo stature estimates and range of variability obtained from the footprints within a broader picture (Figure 12), and to compare them with a larger sample, we extended our analysis to consistent data based on skeletal elements, namely femurs (see Materials and methods for details).

The Kanapoi elbow, dated at 4.5 million, is «fully human», so all these australopithecines and whatnot can not be ancestral to us because a modern human was already in existence; his thorough - or, let us say, thoroughly selective - combing of the literature has overlooked a paper by Marc R.
