All terrestrial life came from the sea, but how did life develop in the ocean? Professor Tim Lenton of the University of Exeter, who led a new study, said: “There had been enough oxygen in ocean surface waters for over 1.5 billion years before the first animals evolved, but the dark depths of the ocean remained devoid of oxygen. We argue that the evolution of the first animals could have played a key role in the widespread oxygenation of the deep oceans. This in turn may have facilitated the evolution of more complex, mobile animals.”
And what were these animals that oxygenated the oceans? Sponges, according to the the new research. Sponges may lack the brains and other organs of more complex animals, but they are animals nonetheless, and around 700 million years ago, sponges began to flood the oceans with oxygen. The oceans had had relatively little oxygen and could not support more complex life.

According to the historic coating specialists, Michael Crick-Smith and Ian Crick-Smith, the current black and orange-yellow color scheme of Nelson’s flagship HMS Victory is “an early 20th century invention of what an 18th century warship looked like.” Based on their study of hundreds of fragments of the original paint surfaces, they have concluded that the original ochre was a much paler yellow instead of what they refer to as “that hideous orange.” Many interior spaces were also said to be less elaborately and brightly colored than they are now on the famous ship.

This morning, the press was abuzz with reports that last Monday, in the Mediterranean off Cyprus, US Navy SEALS boarded and took control of an oil tanker, Morning Glory, which had recently loaded a cargo of Libyan oil in the port of Sidra.
