Early brain growth in Homo erectus and implications for cognitive ability

Article Abstract:

The results of an analysis of the 1.8-million-year-old Mojokerto child (Perning 1, Java), the only well preserved skull of a Homo erectus infant, by computed tomography is presented. It is suggested that in Homo erectus only a short period of brain maturation took place in the extra-maternal environment and this makes it unlikely that early Homo had cognitive skills comparable to those of modern humans.

Effect of evaporite deposition on early cretaceous carbon and sulphur cycling

Article Abstract:

The impact of the South Atlantic evaporite sequences on the global cycling of sulphur and carbon is explored. The results suggest that large-scale evaporite depositional events could greatly alter the sulphate concentration of ocean water and could affect the ability of the marine subsurface biosphere to remineralize organic matter and to mediate pyrite formation.
