<jats:p> Hawks <jats:italic>et al</jats:italic> . argue that our analysis of <jats:italic>Australopithecus sediba</jats:italic> mandibles is flawed and that specimen LD 350-1 cannot be distinguished from this, or any other, <jats:italic>Australopithecus</jats:italic> species. Our reexamination of the evidence confirms that LD 350-1 falls outside of the pattern that <jats:italic>A. sediba</jats:italic> shares with <jats:italic>Australopithecus</jats:italic> and thus is reasonably assigned to the genus <jats:italic>Homo</jats:italic> . </jats:p>

<jats:p> Li <jats:italic>et al</jats:italic> . (Reports, 18 April 2014, p. 292) proposed a unity nitrous acid (HONO) yield for reaction between nitrogen dioxide and the hydroperoxyl-water complex and suggested a substantial overestimation in HONO photolysis contribution to hydroxyl radical budget. Based on airborne observations of all parameters in this chemical system, we have determined an upper-limit HONO yield of 0.03 for the reaction. </jats:p>

<jats:p> Ye <jats:italic>et al</jats:italic> . have determined a maximum nitrous acid (HONO) yield of 3% for the reaction HO <jats:sub>2</jats:sub> ·H <jats:sub>2</jats:sub> O + NO <jats:sub>2</jats:sub> , which is much lower than the yield used in our work. This finding, however, does not affect our main result that HONO in the investigated Po Valley region is mainly from a gas-phase source that consumes nitrogen oxides. </jats:p>

<jats:p> Villmoare <jats:italic>et al</jats:italic> . (Reports, 20 March 2015, p. 1352) report on a hominin mandible from the Ledi-Geraru research area, Ethiopia, which they claim to be the earliest known representative of the genus <jats:italic>Homo</jats:italic> . However, certain measurements and observations for <jats:italic>Australopithecus sediba</jats:italic> mandibles presented are incorrect or are not included in critical aspects of the study. When correctly used, these data demonstrate that specimen LD 350-1 cannot be unequivocally assigned to the genus <jats:italic>Homo</jats:italic> . </jats:p>
