Trees are the oldest living organisms on Earth

An aspen poplar colony (Populus tremuloides) in the United States is the oldest living organism on the planet: it is thought to be over 80,000 years old. It is considered as one and the same body of about 40,000 individuals, linked by a unique system of roots. Its mass is estimated at more than 6,000 tons.

In the Mediterranean Sea it is posidonia (Posidonia oceanica) which holds the record for old age: this colony of underwater flowering plants is between 80,000 and 200,000 years old.
