The species that are especially likely to develop in biologically isolated areas such as islands are called

Endemic species are those especially likely to evolve in biologically isolated areas such as islands, found nowhere else.

Extinct species are those that have died out completely, not ones evolving in isolation.

Wild species is a broad term for undomesticated life, not specific to isolated evolution.

Since endemic names it exactly, none of the above does not apply.

Isolation cuts off gene flow, letting island populations diverge into unique forms.

Endemic island species are often highly vulnerable to invasive predators and habitat loss.
