Human Evolution
A 2.6-million-year-old jawbone discovered in Ethiopia's Afar region marks the first known fossil of the robust hominin Paranthropus from that area. Found about 1,000 kilometers north of previous sites, the specimen suggests this early human relative was more adaptable and widespread than previously thought. Led by University of Chicago paleoanthropologist Zeresenay Alemseged, the discovery challenges long-held views on hominin competition and evolution.

A University of Cambridge study ranks humans among the most monogamous mammals, closer to beavers and meerkats than to chimpanzees. By analyzing sibling ratios across species and human societies, researchers found that long-term pair bonding is unusually prevalent in our species. Even in cultures allowing polygamy, human monogamy exceeds that of most other mammals.
An international team of researchers has discovered the earliest Neanderthal footprints in Portugal along the Algarve coast, dating back up to 82,000 years. These findings reveal insights into Neanderthal behavior, social structure, and diet. The site highlights their adaptability in coastal environments.

Researchers have analyzed proteins from 2-million-year-old teeth of Paranthropus robustus, revealing unexpected genetic variations and sex differences among the fossils. This paleoproteomics study suggests the species may represent a mix of populations rather than a single uniform group. The findings provide some of the oldest molecular data from African hominin fossils.
