About 4500 years in the past, the ultimate stone was laid on the Nice Pyramid of Giza. The traditional kingdom of Assyria was established. Building started on Stonehenge.
And off the coast of Western Australia, a single seedling of seagrass sprouted up, and remains to be rising to at the present time.
Researchers from the College of Western Australia and Flinders College have decided that a 200-square-kilometre patch of seagrass is the one plant, and the most important and oldest plant on the earth.
The researchers had taken samples of seagrass shoots throughout Shark Bay to find out the range of plants there.
And so they had been shocked to find it was truly only one plant.
"That is it, only one plant has expanded over 180km in Shark Bay, making it the most important recognized plant on earth," lead writer Jane Edgeloe stated.
"The prevailing 200 sq. kilometres of ribbon weed meadows seem to have expanded from a single, colonising seedling."
Since then it has survived exceptional ranges of fixing local weather, and the hungry chomps of a whole lot of generations of dugongs.
Australia's most endangered animals
Flinders College ecologist Martin Breed stated they had been baffled at how the plant has survived and thrived so lengthy.
"Our seagrass has seen its fair proportion of environmental change too. Even right now, it experiences an enormous vary of common temperatures; from 17C to 30C," he stated.
"Salinities from regular seawater to double that. And from darkness to excessive excessive mild situations.
"These situations would usually be extremely tense for vegetation. But, it seems to maintain on going."
The researchers at the moment are conducting varied experiments on the seagrass to grasp the way it survives and thrives.
The analysis into the plant has been revealed within the Proceedings of the Royal Society B journal.
Shark Bay is a World Heritage website about 800km north of Perth.
It's house to dolphins, whales, sharks, dugongs and rays, in addition to a variety of endangered animals.
