 Evolutionary suicide has also been referred to as "Darwinian extinction", "runaway selection to self-extinction", and "evolutionary collapse".The idea is similar in concept to the tragedy of the commons and the Tendency of the rate of profit to fall, namely that they are all examples of an accumulation of individual changes leading to a collective disaster such that it negates those individual changes.Many adaptations have apparently negative effects on population dynamics, for example infanticide by male lions, or the production of toxins by bacteria.
