A population becomes isolated on an island (or sometimes in a fragmented ecosystem such as a lone mountain top) and begins to adapt to the local conditions. These adaptations are more important to their survival than maintaining the ability to reproduce with related populations that they are isolated from. Over time, populations that don't have regular contact may lose the ability to interbreed. Additionally, island populations are frequently small (or go through catastrophic population declines -- think hurricanes) and as such are subject to genetic drift. Genetic drift allows for stochastic events like the fixation of rare alleles. On occasion these rare alleles are not compatible with alleles from other populations, resulting in further reproductive isolation. Over time, selection for local adaption and genetic drift combine to create an endemic species.

Species that are geographically isolated to one or a few localities are called endemic species. Endemic species evolve when populations are reproductively isolated from other populations of the same species for a sufficiently long period of time evolving to adapt to their new environment.

A species that is endemic is unique to a defined place or region (in other words only found in that place or region) and not naturally found anywhere else, whereas a species that is indigenous to somewhere may be native to other locations as well.

so in attempts to answer your question "do species evolve into endemic species" so if they adapt to an environment that is only in one location that cant be found anywhere else or evolved to eat plants that are only found in one location.

I don't think endemic means what you think it does. Endemic means that a species is exclusively native to a particular area. So are you asking how a species evolves to live in one area?
