Washington, Apr 22 : Humans might take into account many factors while deciding a house for themselves, it''s the ants who score over them when it comes to choosing the best home possible, according to a new study.
In the study, led by Dr Elva Robinson in the University''s School of Biological Sciences, researchers fitted rock ants with tiny radio-frequency identification tags, each measuring 1 / 2,000 (one two-thousandth) the size of a postage stamp.
They then observed as they chose between a poor nest nearby and a good nest further away.
