What evidence exists on iceland that supports the theory of evolution?

• pretty much im doing a report on iceland, and i need evidence that supports evolution on iceland and i need help finding it

• Answer:

  In Lake Þingvallavatn, which got isolated during the end of last Ice Age, you can find four separate varieties of Arctic charr, none of which are found anywhere else in the world. In the lake you will also find brown trout and three-spine stickleback, both unique to that location. As says in the last source I link to below: "These three species are a living testimony to how the evolution of species occurs in nature, as over a period of 10,000 years they have adapted themselves to various habitats in the lake. The constant, regular influx of groundwater into Lake Þingvallavatn, together with a very varied habitat, has created good conditions for fish and other life forms in the lake, to which they have adapted even more. Such evolution is reflected in the different types of Arctic charr and stickleback, along with varying populations of brown trout. Because of this, Þingvallavatn has recently become a focus of research activity on the first stages of variety and species formation." Another thing in Iceland, which may not be as directly connected to evolution, is that there are unique archaea in geysers and geothermal areas in Iceland. These archaea give be great information about bacterial evolution as well as being an indicative of the perseverance of life, living in the least habitable areas on the surface of the earth.
