🐟🧪 Biologists from #Acadia University and the University of #BritishColumbia studied how #psilocybin affects the behavior of the aggressive mangrove rivulus #fish.

#Data indicated that the compound reduces territorial displays while allowing normal social interactions to continue. The findings suggest that the psychoactive ingredient in magic #mushrooms can dampen social conflict in #vertebrates.

Why do some clades contain far more #species than others? By testing competing explanations across terrestrial #vertebrates, this study reveals that #biodiversity patterns are most often shaped by long-term productivity-driven equilibrium dynamics @PLOSBiology https://plos.io/4vuS10G

🪱🌊 New #research indicates that our eyes developed from a midline light-sensing organ in a primitive sea creature.

While our ancestors lost their original paired eyes while living as stationary filter feeders, the need for movement eventually triggered the #evolution of the complex retinas we use today. This process also led to the formation of the pineal gland, which regulates sleep cycles in modern #vertebrates.

#Eyes of the world's longest-living #vertebrate, the #GreenlandShark, show little #ageing
Greenland #shark (Somniosus microcephalus) can live for up to 400 years in the chilly North Atlantic and Arctic waters, making it one of the longest-living #vertebrates on Earth. And according to new research its seemingly undead eyes are fully functioning and barely deteriorate even after a century. Unravelling the shark's anti-ageing secrets could benefit human eye health.

Four-limbed #vertebrates, known as tetrapods, have two enlarged areas in their spinal cords. The two enlargements have a correlation with the forelimbs and hind limbs, respectively. These enlargements are thought to be caused by the complex muscular system and the rich sensory networks supplying #nerves to the limbs.

Fish that limbed #vertebrates evolved from don't have obvious digit equivalents, most common types of fish just have a large collection of rays supporting their fins.
It turns out hox gene activity in digits isn't the ancestral state; instead, it seems to have #evolved separately in the ray-finned fish and vertebrate lineages.

`Our observations highlight Norselaspis as a prelude to the intercalation of the muscular neck and throat that would power the early jaw apparatus. Therefore, the vertebrate jaw—often considered the functional driver for ‘gnathostome’ innovations1,2,3—evolved instead as a follower to the sensory enhancement, increased cardiac output and greater locomotory control now inferred in the jawless sister group.`

We probably inherited our #joints from… a #fish
#Cartilaginous fish form the same style of joint that we do, while jawless fish don't.
Humans, other land #vertebrates, and jawed fish have #synovial joints. The lubricated cavity within these joints makes them more mobile and stable because it allows for bones or cartilage to slide against each other without friction, which facilitates movement.

We Already Knew That #Cephalopods Were Intelligent, but Not to This Extent: A #Cuttlefish Has Passed a Test Designed for #Children

#Scientists have long known that cuttlefish are #intelligent, but a new study reveals a skill no one expected. In a test originally designed for children, these #marine creatures displayed an astonishing level of self-control.

A new study has revealed that common #cuttlefish (#Sepia officinalis) are capable of delayed #gratification, a trait previously thought to be exclusive to intelligent #vertebrates.
