In the last set of lectures we will look at the modern biodiversity. There is an enormous difference between the biodiversity of different types of habitats on our planet – from the equator to the arctic, from deserts to rainforests, and from isolated islands like the Galapagos to large continents. Jon Fjeldså will take you on a trip around the planet and give you many interesting examples of these variations. He will explain how we can use them to get a better understanding of how evolution works. This concludes the Origins course. Thank you for following it, we hope it has enhanced your understanding of how life evolved and diversified on our planet, and that it will inspire you to see natural phenomena in a new light.
