New human ancestor discovered in Ethiopia

Fossils reveal new human ancestor from 2.8-2.6M years ago in Ethiopia.

Why it matters

  • Reveals a new species in the human family tree.
  • Shows multiple hominin species coexisted in eastern Africa around 2.5-3 million years ago.

By the numbers

  • Fossils dated between 2.8 and 2.6 million years ago.
  • At least four hominin lineages coexisted in eastern Africa during that period.

The big picture

  • Human evolution is complex, with multiple branches (more like a bush than a tree).
  • Challenges the linear view of human evolution.

What they're saying

  • Paleontology is a young field, and each discovery adds to the story of human evolution.

Caveats

  • More fossils needed to name the new species.
  • Findings based on teeth and comparisons with other fossils.

What’s next

  • Further research on tooth enamel to understand diet.
  • Investigating how multiple hominin species coexisted.
