Due to the lack of natural predators, the wildlife in the Galápagos is extremely tame and has no instinctive fear. [1] The Galápagos Islands are home to a remarkable number of endemic species. The stark rocky islands (many with few plants) made it necessary for many species to adapt to survive and by doing so evolved into new species.
The Galápagos spreading centre (GSC) consists of two main sections, linked by the Galápagos Transform (GT). The western section extends from the propagating tip of the GSC (about 30 km east of the East Pacific Rise) for about 1200 km (750 miles) to the northern end of the transform.

Without tourism on the Galapagos Islands, animals are free to inhabit the once human-occupied spaces. Researchers discover that wildlife is reclaiming the Galapagos after tourism stalls Skip to ...
The Galapagos hotspot has a very complicated tectonic setting. It is located very close to the spreading ridge between the Cocos and Nazca plates; the hotspot interacts with both plates and the spreading ridge over the last twenty million years as the relative location of the hotspot in relation to the plates has varied.
Coastal lakes, moist soil and areas where freshwater and seawater mix contain unique species still to be studied. Cold, hot and warm marine currents come together here, generating a wide diversity of animal life: from small coloured fish to large mammals: [3] marine iguanas, Galapagos land iguanas, galapagos crabs, Galápagos sea lion, Sharks, Blue footed boobie, swallow-tailed gulls, ducks ...
For example, 50% of endemic bird areas are found on islands. [2] Endemism is often the result of adaptive radiation. [1] Adaptive radiation is when a single species colonizes an area and rapidly diversifies to fill all of the available niches. A common example is the assemblage of finch species documented by Charles Darwin in the Galapagos ...
