Paleontologists have been divided over exactly how and when early Asian anthropoids made their way from Asia to Africa. The trip could not have been easy, because a more extensive version of the modern Mediterranean Sea called the Tethys Sea separated Africa from Eurasia at that time.
The search for the origin of early anthropoids-and, by extension, early human ancestors-is a focal point of modern paleoanthropology. The discovery of Afrasia shows that one lineage of early anthropoids colonized Africa around 37?? million years ago, but the diversity of early anthropoids known from the Libyan site that produced Afrotarsius libycus hints that the true picture was more complicated.
