The Once-In-An-Eon Event That Gave Earth Plants Has Happened Again https://www.iflscience.com/the-once-in-an-eon-event-that-gave-earth-plants-has-happened-again-73878 > An event that is only known to have happened three times before in the history of life on Earth has just been documented again. A marine bacterium was subsumed into its algal host organism, co-evolving with it for long enough that it can now be considered an organelle, part of the alga’s cellular machinery. That means these algae are the first eukaryotes (organisms with their DNA in a membrane-bound nucleus) known to contain an organelle capable of fixing nitrogen.

Huge undersea wall dating from 5000 BC found in France ![](https://ichef.bbci.co.uk/news/1024/cpsprodpb/0ca9/live/f70b33a0-d6b0-11f0-9fb5-5f3a3703a365.jpg.webp) > With an overall mass of 3,300 tonnes, the wall must have been the work of a substantial settled community. And to have lasted 7,000 years, it was clearly an extremely solid structure. > "It was built by a very structured society of hunter-gatherers, of a kind that became sedentary when resources permitted. That or it was made by one of the Neolithic populations that arrived here around 5,000 BC," said archaeologist Yvan Pailler.
