Definitions of the terms alien species/plants and invasive
... 1.) It is important to notice that both words 'alien' and 'invasive' are always related to organisms in a given area. This may be a continent, a region, a country or a part thereof, e.g., a city (as in "The alien flora of Salzburg") etc. This means that a species may be alien to one, but indigenous ...

Recently discovered fossils at Oregons John Day Fossil Beds National Monument reveal a new species that scientists believe was the last non-human primate in North America. The small, lemur-like animal is believed to have crossed a land bridge at the Bering Strait about 29 million years ago, according to Dr. Joshua Samuels, John Day Fossil Beds National Monument chief of paleontology. This new species shows little resemblance to other North American primates, said Samuels. Where it came from and how it is related to other primates has long been a mystery.
... Primates appeared in North America about 55 million years ago and have a rich fossil record on this continent. The closed canopy forests these primates inhabited began to dwindle, being replaced by more open woodland and savannah habitats as global climate conditions changed. Primate species declin ...

Fauna of Africa
Fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical ecoregion. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife.
