| Open AccessPleistocene climate variability in eastern Africa influenced hominin evolution
Over the past 620,000 years, three distinct phases of climate variability in eastern Africa coincided with shifts in hominin evolution and dispersal, according to an analysis of environmental proxy records from a core collected in the Chew Bahir basin of Ethiopia.

Jurassic shift from abiotic to biotic control on marine ecological success
Controls on the ecological success of marine calcifiers changed from abiotic to biotic in the mid-Jurassic, according an environmental forcing model compared with skeletal taxa.

Geological and climatic influences on mountain biodiversity
Species richness in mountain environments is linked to mountain-building and climatic processes, an integration of geological, climatic, and biological datasets reveals.

Resilience of Pacific pelagic fish across the Cretaceous/Palaeogene mass extinction
The Cretaceous/Palaeogene mass extinction caused ecosystem upheaval. Fish abundance data from the Tethys Sea and the Pacific Ocean indicate heterogeneity in the extinction and recovery, with greater resilience in the Pacific.

Co-evolution of eukaryotes and ocean oxygenation in the Neoproterozoic era
The oxygenation of the Earth's deep oceans is often thought to have triggered the evolution of simple animals. A review article proposes that instead, the evolution of animal life set off a series of biogeochemical feedbacks that promoted the oxygenation of the deep sea.

The timing and pattern of biotic recovery following the end-Permian mass extinction
Over 90% of species were lost during the end-Permian mass extinction. A review of the fossil record shows that the rate of recovery was highly variable between different groups of organisms as a result of complex biotic interactions and repeated environmental perturbations.

Adaptive evolution of a key phytoplankton species to ocean acidification
Ocean acidification may seriously impair marine calcifying organisms. Emiliania huxleyi, the world’s single most important calcifying organism, may be able to evolve in response to ocean acidification conditions, according to laboratory selection experiments.

Palaeozoic landscapes shaped by plant evolution
Throughout the Palaeozoic era, about 540 to 250 million years ago, plants colonized land and rapidly diversified. An analysis of the palaeontologic record shows that this diversification irrevocably altered the shape and form of fluvial systems.

Promoting marine origination
The rate at which new marine animals evolve has varied through time, but the factors that ultimately drive these fluctuations are unclear. A statistical analysis shows that global changes in abiotic factors play an important role.

Effect of nutrient availability on marine origination rates throughout the Phanerozoic eon
The diversity of marine life has varied throughout the past 500 million years. Statistical analyses suggest that fluctuations in the availability of marine nutrients has been one important regulator of rates of origination during this time.
