One of the great mystery story of flora biology is a on the face of it immortal tree diagram call the Trembling Aspen ( Populus tremuloides ) , which reproduces by growing clones from its root organisation . A newfangled survey suggest that the Sir Herbert Beerbohm Tree live for 20,000 year .
Because these aspens live for so long , nobody had been capable to determine exactly how many years the trees endure before they begin to show mansion of ripening . So University of British Columbia life scientist Dilara Ally determined to regain out . She defined “ get on ” as “ diminishing natality , ” and she measured prolificacy just by essay how much pollen was being let go by the male trees ( she did n’t include female trees in the cogitation ) . She also figure out years of the clones via “ molecular clock ” – looking at how many mutations they had in their genomes , since each successive genesis of clones gets more and more mutated .
concord to Robin Meadows , who cover the study for PLoS :
The aspen clones studied ranged from roughly 70 to 10,000 years old , and pollen analytic thinking bring out a dim but steady loss of fertility with years . birthrate was cut by more than three - quarters in the oldest dead ringer and , based on extrapolation , would likely have dwindled away completely by 20,000 years . Thus , though it may take millennium , even plants that grow indefinitely will eventually succumb to old old age .
Still , it ’s absolved that if you want to live for millennium , clone yourself is the agency to go .
