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.

A Mexican cavefish with a scarred heart

Scientists are studying a guppy-sized, blind, translucent fish that lives in the cave systems of northern Mexico to figure out why some animals can regenerate their hearts, while others just scar.

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.
