Camels – Early camels originally came from North America. They migrated to other places including East Asia, Africa and South America. Once camels reached these different places, they evolved independently. They evolved adaptations that suited them for the particular environment where they lived. Through natural selection, descendants of the original camel ancestors evolved the diversity they have today. Coming from the same ancestors and descendants, the major changes can be compared by the sizes of their humps that depends on the places they live. Comparatively, South American Camel Species, like the llamas doesn’t have humps while Saharan African Camels do have larger and bigger humps needed to survive the extreme weather conditions of Africa.
Describe two examples, one plant and one animal, of how biogeography supports evolutionary theory.
