This difficulty leads to phenomena such as Lazarus taxa‚ where a species

    Extinction is the ceasing of a species to exist on this Earth. A species officially becomes extinct when all of the species no longer exists.

Therefore‚ we say a species is in for certain extinction if it cannot reproduce itself. Extinctions occur at a great pace and species that we did not even know existed become extinct all the time. Scientists say that

    Animal extinction Animal extinction has been dramatically occurring and this is the biggest issue in the planet.
