Cultural and linguistic networks of central African hunter–gatherers have ancient origin, study finds

Extensive social networks between different hunter–gatherer groups in the Congo Basin existed long before agriculture arrived in the region. This continent-wide exchange preserved a cultural diversity that evolved thousands of years ago, as researchers from the University of Zurich have shown based on musical instruments, specialized vocabulary and genetic information.

Researchers succeed for first time in accurately dating a 7,000-year-old prehistoric settlement using cosmic rays

Researchers at the University of Bern have for the first time been able to pin down a prehistoric settlement of early farmers in northern Greece dating back more than 7,000 years to the year.

Researchers discover hidden step in dinosaur feather evolution

Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.

This photo was sent my way by someone who knows I work in #food security. I don’t know where it was taken or who deserves credit. (The tickets appear to name a pub).

But I’d sure love to see this kindness replicated. Widely. It’s critically needed & warms my heart. ❤️

3D mouth of an ancient jawless fish suggests they were filter-feeders, not scavengers or hunters

Early jawless fish were likely to have used bony projections surrounding their mouths to modify the mouth's shape while they collected food. Experts have used CT scanning techniques to build up the first 3D pictures of these creatures, which are some of the earliest vertebrates (animals with backbones) in which the mouth is fossilized. Their aim was to answer questions about feeding in early vertebrates without jaws in the early Devonian epoch -- sometimes called the Age of Fishes -- around 400 million years ago.

In the evolution of walking, the hip bone connected to the rib bones

A new reconstruction of the 375-million-year-old fossil fish Tiktaalik -- a close relative of limbed vertebrates -- used micro-CT to reveal bones still embedded in matrix. The reconstruction shows that the fish's ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking.
