▁O live ▁trees ▁ ▁A ▁study ▁conducted ▁by ▁the ▁National ▁Research ▁Council ▁of ▁Italy ▁in ▁ 2 0 1 2 ▁found ▁that ▁several ▁o live ▁trees ▁in ▁the ▁garden ▁are ▁amongst ▁the ▁oldest ▁known ▁to ▁science . ▁D ates ▁of ▁ 1 0 9 2 , ▁ 1 1 6 6 ▁and ▁ 1 1 9 8 ▁AD ▁were ▁obtained ▁by ▁carbon ▁d ating ▁from ▁older ▁parts ▁of ▁the ▁tr unks ▁of ▁three ▁trees . ▁DNA ▁tests ▁show ▁that ▁the ▁trees ▁were ▁originally ▁plant ed ▁from ▁the ▁same ▁parent ▁plant . ▁This ▁could ▁indicate ▁an ▁attempt ▁to ▁keep ▁the ▁line age ▁of ▁an ▁older ▁species ▁int act . ▁Then ▁again , ▁the ▁three ▁trees ▁tested ▁could ▁have ▁been ▁spr outs ▁rev iving ▁from ▁the ▁older ▁roots . ▁ ▁" The ▁results ▁of ▁tests ▁on ▁trees ▁in ▁the ▁Garden ▁of ▁G eth sem ane ▁have ▁not ▁settled ▁the ▁question ▁of ▁whether ▁the ▁g nar led ▁trees ▁are ▁the ▁very ▁same ▁which ▁shelter ed ▁Jesus ▁because ▁o live ▁trees ▁can ▁grow ▁back ▁from ▁roots ▁after ▁being ▁cut ▁down ", ▁research ers ▁said . ▁ ▁However , ▁Bern abei ▁writes : ▁" All ▁the ▁tree ▁tr unks ▁are ▁h ollow ▁inside ▁so ▁that ▁the ▁central , ▁older ▁wood ▁is ▁missing ... ▁In ▁the ▁end , ▁only ▁three ▁from ▁a ▁total ▁of ▁eight ▁o live ▁trees ▁could ▁be ▁successfully ▁dated . ▁ ▁The ▁dated ▁ancient ▁o live ▁trees ▁do , ▁however , ▁not ▁allow ▁any ▁hypothesis ▁to ▁be ▁made ▁with ▁regard ▁to ▁the ▁age ▁of ▁the ▁remaining
