In August 1994, a ranger named David Noble was exploring a remote canyon in Wollemi National Park, about 150 kilometers northwest of Sydney. He climbed down into a gorge and found a grove of trees he did not recognize. He collected samples. When he brought them back, botanists could not identify them either. Eventually the samples reached a paleobotanist who recognized the pollen structure: it was identical to fossils found in Australian geological formations dating back more than 90 million years. The tree was known to science only as a fossil. It had been extinct, on paper, since the Cretaceous. There were approximately 60 trees in that one canyon. All of them genetically identical. Not similar, identical: the wild population appears to have zero genetic variation between individuals, which suggests that what exists today may be the last survivors of a single ancient individual that has been reproducing vegetatively for millions of years. Scientists called it the botanical find of the century. The location was kept secret. It remains restricted. The trees have been propagated in cultivation worldwide. But the wild population is still 60 trees in one canyon in the Blue Mountains, in country that has been inhabited by Aboriginal Australians for at least 65,000 years, near a city of 5 million people, undiscovered until 30 years ago. #exotictrees #forestfacts #nature #science
Acho que deveríamos começar a enfiar isso em todos os médicos homens uma vez por ano, até que mudem o design.
