A colony of 48,000 quaking aspen trees (nicknamed Pando), covering 106 acres (43 ha) in the Fishlake National Forest of Utah, is considered one of the oldest and largest organisms in the world. Recent estimates set the colony's age at several thousand (up to 14,000) years, although tree ring samples date individual stems at rarely more than 130 ...
Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 370 million years ago, and it is estimated that there are around three trillion mature trees in the world currently.
More than 99 percent of all species that ever lived (over five billion) [1] are estimated to be extinct. [ 2 ] [ 3 ] Estimates on the number of Earth's current species range from 10 million to 14 million, [ 4 ] with about 1.2 million or 14% documented, the rest not yet described . [ 5 ]
Most of these plants have true roots and leaves, and many were quite tall. The tree-like Archaeopteris, ancestral to the gymnosperms, and the giant cladoxylopsid trees had true wood. These are the oldest known trees of the world's first forests. Prototaxites was the fruiting body of an enormous fungus that stood more than 8 meters tall. By the ...
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
Using this 2,000-year data set, they calculated that the summer of 2023 was 2.2 degrees Celsius hotter than the long-term pre-industrial average, before robust networks of instruments could ...
Each of the trees in this stand is a genetically identical male that has reproduced vegetatively. Although no single tree in this stand is of that age, the stand itself as a single organism has existed that long. [116] Individual trees in the clonal patch have been listed as having ages of 2000 [117] [118] or even to 3000 years old. [119] [120]
