Ants plain know precisely when they ’ll die , and when the insects are closer to decease they choose to do more risky job like foraging for food far from the nest . Many scientist had honor that older emmet run to take on wild job , but had postulated that this was just a function of long time . But a group of researchers in Poland , conduct by Dawid Moron , published a nervous article in Animal Behavior demonstrating that every ant experience when it will die , and the closer it get to decease , the riskier its demeanour pay back . Moron and his squad expose ants to carbon monoxide , which shortens their life well , and discovered that the damaged emmet set off doing speculative things at a new age , incriminate that they realized they were shortly to die despite their relative youth .
Says Moron :
This imply that ant workers set their threshold for take in risk scrounge accord to their lifetime expectancy .
cognise when you ’ll die sounds like a nightmare , but ants have managed to change state it into useable altruism . have sex when it will die have each ant make a rational decision to face danger that could gain the relaxation of the nest . After all , it ’s going to die pretty soon anyway , so it might as well do a bunch of potentially fatal things beforehand . look-alike byBill acclaim .
