Evolution: South Africa's hominin record is a fair-weather friend
The fossil record of early hominins in South Africa is biased towards periods of drier climate, suggests a study of cave deposits. This finding suggests there are gaps in the fossil record, potentially obscuring evolutionary patterns and affecting our understanding of both the habitats and dietary behaviors of early hominins in this region. South Africa's highest concentration of early hominin fossils comes from the 'Cradle of Humankind' caves northwest of Johannesburg.

Scientists find stable sea levels during last interglacial
The magnitude and trajectory of sea-level change during the Last Interglacial, more specifically Marine Isotope Stage (MIS) 5e, is uncertain. To date the consensus view has been that sea-level may have been six to nine meters above present sea level. However, scientists are now questioning if those sea level fluctuations are accurate.
