No, it is not true that when a new species emerges, the old species is eliminated.
Because when there is a change in any species, the change is only in a part or a few
members of the species population. If the newly generated species after genetic
change is better in any way, it will get more opportunity to survive; if the genetic
change is against the environment, it will die. Thus, unchanged members of other
species may also remain and tend to live in the changed environment.
