Record-breaking divers are pushing human limits and reshaping scientists' view of our species
Humans have a long history of diving to forage from the seabed and today elite freedivers are reaching greater depths than ever. Some researchers argue humans belong in the sea.

When did the lubricated joints that allow our skeleton to swivel, rotate and bend evolve? @crumplab.bsky.social explores a new @plosbiology.org paper by @neelimasharma.bsky.social &co that pinpoints their origin to the earliest jawed vertebrates 🧪 Paper: plos.io/3CTC8La Primer: plos.io/4kkhXa6
Left: A phylogeny of chordates, flanked by images of a lamprey, a placoderm, a brown shark, a longnose gar and a hawksbill turtle. Agnathans such as lampreys lack synovial joints. The first putative evidence of synovial joints in the fossil record is in early gnathostomes such as the antiarch placoderm fish that lived during the Silurian and Devonian periods. Modern gnathostomes such as cartilaginous fishes (i.e., chondrichthyans such as the brown shark), bony fishes (i.e., osteichthyans such as the longnose gar), and limbed vertebrates (i.e., tetrapods such as the Hawksbill turtle) possess synovial joints in their jaws, fins/limbs, and other locations. All images used are freely available without copyright restrictions. Top right: a typical agnathan joint is shown where glycosaminoglycans and proteoglycans are uniformly distributed across the cartilages (blue) that are connected by fibrous tissue (olive). Bottom right: a typical gnathostome synovial joint is shown where surface cartilage has a unique proteoglycan composition from the underlying cartilage and bone, and a fluid-filled cavity separates adjacent skeletal elements.

Yellow-breasted capuchins use stones as nutcrackers, often inadvertently creating sharp-edged flakes, like those associated with early hominids, in what the authors suggest is a possible mechanism for the emergence of hominin stone tools. In PNAS: www.pnas.org/doi/full/10....
