Ants have a sense of their own mortality - life - 10 October 2007 - New Scientist
It appears that we humans are not the only living creatures that have a sense of their own mortality. What are the implications of this? We have always used the term "dumb animals" to describe all animals except for ourselves assuming that we had some awareness of our own mortality that was lacking in animals. Also interesting that the ants increase their risk taking the older they get which is in direct opposition to what humans usually do.
