US EditionFossil teeth reveal a previously unknown human ancestor from eastern Africa
- Scientists uncovered 13 fossilized teeth at Ethiopia's Ledi-Geraru site, dating back approximately 2.6 to 2.8 million years, which reveal the presence of both early Homo and newly identified Australopithecus species.
- This discovery follows the 2013 finding of a 2.8-million-year-old Homo jaw and aims to clarify the coexistence and distinctions between Homo and Australopithecus species.
- The teeth came from three separate ash layers dated by volcanic activity, with Homo teeth in the oldest and youngest layers and Australopithecus in the middle one, indicating overlapping habitats.
- Lead researcher Brian Villmoare emphasized that the discovery of Homo fossils dating back approximately 2.6 to 2.8 million years provides important evidence confirming the early existence of our human lineage.
- The findings suggest a more complex, bushy human evolutionary tree with multiple hominin species coexisting, challenging linear progression views and requiring further fossil evidence for confirmation.
