Panina

Quality 0.00 · 0 views · Updated 20 days ago

Panina is a subtribe of tribe Hominini; it comprises all descendants of the human-chimpanzee last common ancestor (LCA) that are not of the branch of human lineage—that is, all those ancestors of the type genus Pan (chimpanzees and bonobos). This split/divergence occurred around 8 to 6 million years ago (mya), which compares with a range of other estimates for this event—likely extended by periods of hybridization—of from 15 to 3 mya. Fossils from this subtribe are typically rare because they tend to live in environments with poor fossilization. Some of the earliest chimpanzee fossils are 500,000 years of age.
