What the central idea of against all odds Earths fragile pioneers

The central idea of "Against all odds: Earths fragile pioneers" is how Hawaii which is the most isolated island group on earth slowly was colonized by plants and animals.

Explanation:

Despite Hawaii's seclusion from the world, life got there through three means: wind, wings and water. Insects and seeds travel on birds that migrate or flee storms. Jet stream causes wind to move from Asia to Hawaii carrying seeds. And sometimes insects like cricket, and various seeds like hala reached Hawaii floating on the ocean. All these organisms faced harsh conditions, adapted and and now colonize Hawaii.
