A new analysis of the best-preserved Neanderthal infant skeleton shows that these ancient babies developed bones and brains at a pace matching modern humans aged 12 to 14 months, despite being only about six months old. The findings, based on the Amud 7 infant from Israel, suggest Neanderthals grew rapidly in early childhood as an adaptation to harsh environments. Researchers observed similar patterns in other young Neanderthal remains.

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.
