Munich, Feb 15: A simulation developed by researchers has surprisingly suggested that it''s not always the fittest of the species that prevails; sometimes, the weakest can also become a winner.
The extinction of species is a consequence of their inability to adapt to new environmental conditions, and also of their competition with other species.
Besides selection and the appearance of new species, the possibility of adaptation is also one of the driving forces behind evolution.
According to the interpretation that has been familiar since Darwin, these processes increase the "fitness" of the species overall, since, of two competing species, only the fittest would survive.
