Why #vertebrate #eyes so different from those of other animals?
A new hypothesis proposes that our ancestors lost their eyes, then rebuilt them.
“Vertebrate eyes are so fundamentally different from the lateral eyes of other animal groups,” Dan-Eric Nilsson, expert in eye #evolution. “Hey difference is the identity of the main photoreceptor, which is of ciliary nature in the vertebrate eye but rhabdomeric in other animal groups, such as arthropods and cephalopods,” he adds

" For fish and birds, this is described as gradual mouth gaping, staying open for at least three seconds and subsequently a rapid closure of the mouth. Almost all #vertebrate animals, including mammals, birds, reptiles, amphibians, and even fish, experience yawning. "

Eyes, as light-sensing organs of the #lens #eye type, have #evolved independently multiple times in the animal kingdom. But what did a representative of the early #vertebrate lineage look like? According to G. Kafetzis et al. (2026), a worm-like #ancestor possessed #medianeyes bring #homologous to the modern #pinealgland of the #brain. Published in #CurrentBiology. #evolution

#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.

Not sure I should admit this, but in my family, loading dead animals into the car was totally normal. My dad always had a hatchet, saw, knives, and plastic bags in the trunk, and wouldn't hesitate to come to a full stop on a busy highway if he suspected the skull was undamaged. There was one on almost every shelf in the house. The car often smelled bad. #bones #vertebrate #skull

Negatives are often deeper than the positives are tall - so negativitiy bias, in science, news, psychology is understandable.
This is some sobering positive news on vertebrate populations estimations. -
It's very satisfying to see the crown article of my first PhD student Bryan Shirley published! Skeleton is usually all that remains from an animal in the fossil record, so in order to find out how the animal functioned when alive, we have to squeeze out clues from the skeletal tissues, for example using advanced #ElectronMicroscopy 🔬. We were told that vertebrate tissues are too chemically unstable to study this way, but with the help of experts in microscopy, we were able to make rapid measurements of crystallography in the oldest #vertebrate hashtag#teeth to understand how they function evolved. Turns out the crystal orientation reflects the function! From the #ultrastructure we can estimate how the animals were biting and see their evolutionary adaptations at the level of individual crystals 💎 This was possible thanks to the facilities and funding by EXCITE network and Deutsche Forschungsgemeinschaft (DFG) - German Research Foundation

#LostSpecies are those that have not been observed in the wild for over 10 years, despite searches to find them. Lost #tetrapod #species (four-limbed #vertebrate animals including #amphibians, #birds, #mammals and #reptiles) are a global phenomenon—there are more than 800 of them, and they are broadly distributed worldwide.
But, we are losing tetrapod species at a faster rate than we are rediscovering them, researchers say https://phys.org/news/2024-01-tetrapod-species-faster-rediscovering.html -

"Among #invertebrates, several reach trench depths, including the sea cucumber Myriotrochus bruuni at 10,710 in the #MarianaTrench, the extremely abundant amphipod Hirondellea gigas at 10,897 m in the #ChallengerDeep, the isopod Macrostylis species at 10,710 in the Mariana Trench... The deepest known #vertebrate is the hadal #snailfish Pseudoliparis swirei found at 7966 m."

Fossil evidence for a pharyngeal origin of the #vertebrate pectoral girdle https://www.nature.com/articles/s41586-023-06702-4
"The #GillArches seem to have been involved in the early separation of the head and body via the shoulder. But we no longer have gill arches—though the shoulder was templated on them, they don't need to still be around today."

"While our data do not fully reject the active muscle contraction (AMC) hypothesis for #purring, they show that #cat larynges can easily produce sounds in the purr regime with fundamental frequencies of 25 to 30 Hz without neural input or muscular contraction. This strongly suggests that the physical and physiological basis of cat purring involves the same MEAD-based mechanisms as other cat vocalizations (e.g., meows) and most other #vertebrate vocalizations"
