A mass extinction event creates a large gap in the biodiversity of an ecosystem or multiple ecosystems, which results in a rapid period of evolution of a range of different species that weren't particularly specialised to fill that niche.
Is extinction the word you're looking for ?
the answer to the question is extinction
He mainly focused on evolution, natural selection, law of extinction and he even published a book called the Origin of Species. Darwin did many studies that now contributes to newer scientific theories.
Mass extinction isn't a natural role in any life-system. They happen as a consequence of some catatrosphic disaster or radical unbalance in the eco-system. As a result of mass extinctions other 'groups' evolve into species that take the place of those exterminated.
There are many advantages of sexual reproduction including creating genetic variance. Other advantages include having a more stable population, lower rate of extinction, higher rate of evolution, and higher socialization in animals.
The evolution of mammals
Extinction is part of the Theory of Evolution. This goes along with natural selection and survival of the fittest. Organisms that go extinct do so because they are no longer able to survive in the habitat.
Well... we can say that the lack of evolution or evolutionary development can certainly aid extinction. If the environment changes too quickly in a direction that is harmful to a species, then the species needs to either evolve or become extinct.
Extinction of a particular animal species occurs when there are no more individuals of that species alive anywhere in the world. The process of extinction is a natural part of evolution.
