Grasslanda
It creates the gametes that allow a species to continue. It also allows the species to include diversity in order to make the species more fit to survive in its environment.
The diversity of sexually reproducing species is a result of the fact that a) gene pools change over time (by selection and genetic drift) and that b) reproductive isolation occurs, leading to the inability of the descendants of formerly interbreeding subpopulations to interbreed (speciation).

Biology
Mutation
Species resistance is a type of resistance that occurs among all members of a species. This is a part of innate immunity.
Polymorphism or different phenotypes in a single species could be responsible for the diversity in the cnidarians evolutionary tree which happens to be extremely diverse and complex, ultimately increasing its chances of survival.
