Season 1, Episode 1: Origin
The Galapagos archipelago's uniquely diverse wildlife was fit to inspire Darwin's evolution theory. It's also a great place to study evolution at high speed, spurred by volcano-created island building. Species arrive from South America and even across the Pacific in numerous ways, like floating, flying, rafting as well as swimming. They adapt fast. Diversity is no less in the sea, where three deep currents meet, again unique.
Season 1, Episode 2: Adaptation
The case of the famous Galapagos turtle species illustrates, like that of iguanas and spiders, why and how 'immigrant' animals adapt rapidly and diversely. The islands themselves go trough drastic changes during their life cycle, from dormant volcano to barren rock sinking into the ocean, always challenging its residents but becoming interesting for others.
Season 1, Episode 3: Evolution
However small, due to tectonic plate mobility the Galapagos islands are all different, also in ago and hence phase in the volcanic isle life cycle. Even regardless of arriving species, life thus has to adapt unusually quickly to every biotope. The near-absence of major predators often allows faster reproduction, hence evolution. Man's arrival in the 17th century brought new challenges and species.
