History of botany

African ostrich is the only species of Ostrich, and it is also the representative of walking birds. The earliest ostriches appeared in Europe at least during the Eocene, and developed widely in Eurasia from Pliocene to Pleistocene, with a wide variety. In China, there were also fossils of Anglian ostriches, Vickers ostriches and Mongolian ostriches from Pliocene to Pleistocene, which moved to Africa around the Pleistocene, but by the 1 9th century, only African ostriches1species were left.

In the middle of the 20th century, the disappearance of the African ostrich living in Arabian Peninsula also meant the complete extinction of this animal in Asia, making it truly an "African ostrich". In fact, due to a large number of human hunting, the population living in Africa is also declining, especially in northern Africa, and most areas are on the verge of extinction.
