Life on land began 500-million-years earlier than previously thought

Billion year old fossils found on the edge of a remote loch in Scotland is rewriting the history of life on land.

The rocks from around Loch Torridon in Wester Ross show a key moment in the history of life, when simple bacterial cells started to become more complex single cell algae that could reproduce and photosynthesise.

Previous studies had dated the ‘sun and sex revolution’ on land as half a billion years ago.

However the finely ornamented fossils show that the land was green with more larger more complex algae one billion years ago.
