Did a magnetic field collapse trigger the emergence of animals?
Researchers uncovered compelling evidence that Earth's magnetic field was in a highly unusual state when the macroscopic animals of the Ediacaran Period -- 635 to 541 million years ago -- diversified and thrived. Their study raises the question of whether these fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels that may have been crucial to the proliferation of life forms millions of years ago.

Rock solid evidence: Angola geology reveals prehistoric split between South America and Africa
A research team has found that ancient rocks and fossils from long-extinct marine reptiles in Angola clearly show a key part of Earth's past -- the splitting of South America and Africa and the subsequent formation of the South Atlantic Ocean.

Revised dating of the Liujiang skeleton renews understanding of human occupation of China
Researchers have provided new age estimates and revised provenance information for the Liujiang human fossils, shedding light on the presence of Homo sapiens in the region. Using advanced dating techniques including U-series dating on human fossils, and radiocarbon and optically stimulated luminescence dating on fossil-bearing sediments, the study revealed new ages ranging from approximately 33,000 to 23,000 years ago. Previously, studies had reported ages of up to 227,000 years of age for the skeleton.
