Scientists have discovered an early Miocene ape at the biogeographic crossroads of African and Eurasian hominoidea. [Title] This find comes from a site located at the crossroads of hominoid migration routes between Africa and Eurasia. [Contents] The study is published in the journal Science, Volume 391, Number 6792, Pages 1383-1386, March 2026. [Contents] Discovery points to the early Miocene, a period about 20 million years ago when the great apes began to diverge from other primates.[3][5] The find includes a new type of great ape along with two previously known species, bringing the number of vertebrates at the site to 25.[3] The Koru 16 site in western Kenya was preserved by ash from the extinct Tinderet volcano and contains fossils of leaves, soils, and tree trunks.[3][5] The environment was a warm, humid rain forest similar to today's tropical African forest, disturbed by fires, floods and eruptions.[3][5]
