How activity in Earth's mantle led the ancient ancestors of elephants, giraffes, and humans into Asia and Africa

Study Reveals How Elephants Crossed from Africa to Asia

A new study uncovered how ancient land shifts allowed elephants to cross from Africa to Asia millions of years ago. Credit: Vaughan Leiberum / Flickr / CC BY 2.0 A slow geological shift deep beneath the Earth’s surface millions of years ago may have shaped the path of life as we know it. Based on new research published in Nature Reviews Earth & Environment, a plume of rising hot rock helped lift the terrain across what is now the Arabian Peninsu…

Collision, mantle convection and Tethyan closure in the Eastern Mediterranean

The Tethys Seaway once linked the Atlantic and Indo-Pacific oceans. Its gradual shallowing and closure impacted global ocean circulation, faunal diversification and climatic changes. In this Review, we evaluate the tectonic causes and the topographic changes across the Eastern Mediterranean over the past 66 Ma and explore the consequences of Tethys Seaway closure. Mantle convection led to collisional tectonic processes, mountain building and cru…

How activity in Earth's mantle led the ancient ancestors of elephants, giraffes, and humans into Asia and Africa

What roils beneath Earth's surface may feel a world away, but the activity can help forge land masses that dictate ocean circulation, climate patterns, and even animal activity and evolution. In fact, scientists believe that a plume of hot rocks that burst from Earth's mantle millions of years ago could be an important part in the story of human evolution.

Activity In The Earth's Mantle Was Responsible For Leading Our Ancient Ancestors Into Africa And Asia

Explore the Earth's mantle and its role in shaping land, climate, and even the evolution of species over millions of years.

Ancient overpasses may hold the key to understanding human migration from Africa

The formation of a large overpass 20 million years ago connected continents, influenced climate, separated oceans, and changed the course of evolution. According to recent papers published in Nature reviews the Earth and the environment, researchers from various disciplines such as plate tectonics, evolutionary anthropology, and climate research provide a comprehensive summary of the closure [...] Source The post Ancient overpasses may hold the …
