Moss on the Hawaiin Islands is thought to be one of the oldest multicellular organisms on Earth.
The peat moss spreads by making copies of itself meaning that the current crop came from the same founder plant that reached Hawaii tens of thousands of years ago. It is thought that human activity such as its use as a packing material may have helped the moss spread across the islands in recent years. "The peat moss has had explosive growth where it was introduced, especially on Oahu," said study co-author Eric Karlin.
"A moss spreading throughout the Hawaiian Islands (map) appears to be an ancient clone that has copied itself for some 50,000 years—and may be one of the oldest multicellular organisms on Earth, a new study suggests."
