The way the geography of the Middle East changed on the pulse of plate tectonics has been pivotal in shaping how we became human. This article is on how a new young ocean, the Red Sea, opened during the final spasms of an ancient one, the Tethys; and what that meant for migrating species such as our distant human ancestors...

How a new young ocean, the Red Sea, opened during the final spasms of an ancient ocean, the Tethys; and what that meant for migrating species such as our distant human ancestors and hominid relatives. Nowhere but in the Middle East was geography so pivotal in shaping how we became human. A clearer picture of this history is slowly crystallizing,...

By a sublime and unimaginable coincidence, the moon and sun are exactly the right size, and the distances between earth, sun and moon are such that the latter neatly covers the solar disc during that fleeting but dazzling moment of a total solar eclipse. In a path of about 120 miles wide, one of the most splendid sights of...

About six million years ago, almost all the water of the Mediterranean Sea evaporated as it became cut off from the global ocean. In a geological blink of an eye, the sea level dropped until only a few seething lagoons remained, at a depth of roughly 1,500 to 3,000 meters below mean sea leve, causing a huge ecological crisis. But then great natural floodgates opened in the Strait of Gibraltar and through a mega-flood the basin refilled with seawater. Read on.

Lapis lazuli: Via the Silk Road to Tutankhamun.

An article by Kathelijne Bonne

From high mountain peaks to the pharaohs.

How precious stone lapis lazuli found its way from the world's most ancient mines to Mesopotamia, Egypt, and Greece, and to the canvases of the great painters, has been documented extensively. Discover how lapis lazuli formed, as it crystallized in seams of precious rocks in the midst of plate tectonic turmoil.

What is Gondwana?

The inspiration came from the great, lost continent of Gondwana. Gondwana was the land area in which all southern continents were once united into one great supercontinent. When it formed, life had exploded into a myriad of life forms and had risen from a mainly microscopic bacterial world to a world in which animals and plants came to dominate. When Gondwana fell apart, and continents drifted away, new, isolated life forms emerged, of which the peculiar fauna and flora of Australia are the best, but not the only, example.
