Can crows count much like toddlers do? The research was inspired by toddlers learning to count, said lead study author Diana Liao, a neurobiologist and senior researcher at the Tübingen lab. “They understand abstract numbers … and then plan ahead as they match their behavior to match that number,” Williams said. The study by Liao and her colleagues isn’t even the first to consider whether crows can count. The crows’ counting abilities “seem to exceed the demands which survival makes for such abilities,” he wrote.

Neanderthal glue points to complex thinking

CNN —Neanderthals likely made a type of glue from two natural compounds to help them better grip stone tools, according to a new analysis of forgotten artifacts recently rediscovered in a Berlin museum. “The fact that Neanderthals made such a substance gives insight into their capabilities and their way of thinking,” he said. The stone tools were unearthed around 1910 at a French archaeological site called Le Moustier that scientists believe Neanderthals used between 120,000 and 40,000 years ago. Their study, published Wednesday in the journal Science Advances, found that the makers of the stone tools used the adhesive to mold a handle rather than haft the tool to wood. P. SchmidtMicroscopic wear showed the stone tools appeared polished over the handheld part but not elsewhere, likely revealing abrasion from the movement of the tools within the ocher-bitumen grip.

Few complete fossils of this Jurassic sea turtle, named Solnhofia parsonsi, have been discovered. Today’s marine turtle species all have elongated, rigid flippers to propel them through the ocean depths. But the newly described fossil’s limbs were stumpier than those of modern sea turtles relative to its body size. An artistic reconstruction shows the extinct sea turtle in its coastal marine environment. The newly described fossil presents a far more complete view of those limbs, showing that they differed dramatically from the extremities of sea turtles alive today.
