for those of you who do not believe in science, please consult your relevant holy book for more information on the origin of the octopus. Otherwise, this story talks about a very interesting project, the marine census, that still leaves 95% of the world's oceans unexplored. Octopuses had Antarctic ancestor: marine census Sun Nov 9, 2008 5:29pm EST
By Alister Doyle, Environment Correspondent OSLO (Reuters) – Many octopuses evolved from a common ancestor that lived off Antarctica more than 30 million years ago, according to a "Census of Marine Life" that is seeking to map the oceans from microbes to whales. Researchers in 82 nations, whose 10-year study aims to help protect life in the seas, found a mysterious meeting place for white sharks in the eastern Pacific Ocean and algae thriving at 25 degrees Celsius (-13 Fahrenheit) in the Arctic. "We are approaching a picture of the oceans … from micrcobes to whales," said Ron O'Dor, co-senior scientist of the census of the 2007-08 findings by up to 2,000 scientists. The $650 million census is on track for completion in 2010, assessing about 230,000 known marine species, a statement said. It has identified 5,300 likely new species, of everything from fish or corals. So far, 110 have been confirmed as new. Among the findings, genetic evidence showed that the tentacles of the octopus family pointed to an Antarctic ancestor for many deep sea species. A modern octopus called adelieledone in Antarctica seemed the closest relative of the original. Octopuses apparently spread around the world after Antarctica became covered with a continent-wide ice sheet more than 30 million years ago, a shift that helped create oxygen-rich ocean currents flowing north, a report said. "Isolated in new habitat conditions, many different species evolved; some octopuses, for example, losing their defensive ink sacs - pointless at perpetually dark depths," the census said. more here
