Tooth enamel decodes Africa's ancient landscapes shaping early humans

Researchers analyze chemical traces in fossil tooth enamel from Ethiopia’s Afar region to reconstruct how landscapes and diets changed over the past ~4 million years. Enamel preserves signals of what plants ancient animals ate, revealing forests, wetlands, and grassy plains that expanded into open savannas around 2–3 million years ago. The data suggest early hominins like Australopithecus afarensis had flexible, mixed diets, and that environmental shifts helped drive human evolution, including tool use and upright walking.

Africa’s Rift: A Slow Move Toward a New Ocean and New Science

In Ethiopia’s Afar region, a triple-junction rift is slowly pulling Africa apart, providing a rare window into continental rifting as mantle plumes pulse and plates shift at millimeters per year. Scientists study Erta Ale’s lava lake and fossil finds like Paranthropus to understand deep geology, while concluding that a new ocean may form only over millions of years and that the region offers invaluable insights into Africa’s geological history.

Ancient Paranthropus Jawbone Nudges Human Evolution Timeline Northward

A 2.6-million-year-old Paranthropus lower jaw found in Ethiopia's Afar region extends the genus's known range by about 620 miles, implying greater mobility and a more flexible diet that overlapped with early Homo, challenging long-held maps of early human evolution.

Emerging Ocean in Africa: Lava and Mantle Activity Shape a New Rift

Scientists have discovered a pulsing mantle plume beneath Ethiopia's Afar region, which is gradually splitting the continent and may lead to the formation of a new ocean, driven by rhythmic surges of hot mantle material that influence tectonic rifting.

Deep Earth Pulses May Split Africa and Form a New Ocean

Deep beneath East Africa's Afar region, a pulsing mantle plume is causing tectonic plates to diverge, potentially leading to the formation of a new ocean in 20-30 million years as the continent splits along rifts, offering insight into the Earth's geological processes.

Rhythmic Mantle Pulses Beneath Africa May Shape a New Ocean

Scientists have discovered rhythmic pulses in Earth's mantle beneath Africa's Afar region, driven by molten magma, which influence tectonic plate movement, volcanic activity, and the formation of a new ocean basin, providing new insights into Earth's dynamic interior and surface interactions.

Africa's Tectonic 'Heartbeat' Signals Potential Rift Formation

Researchers have discovered rhythmic pulsing of molten magma beneath Ethiopia's Afar region, which is gradually tearing Africa apart and forming a new ocean, revealing a dynamic interaction between Earth's interior and surface processes.
