vertebrate : any of a subphylum (Vertebrata) of chordates that comprises animals (such as mammals, birds, reptiles, amphibians, and fishes) typically having a bony or cartilaginous spinal colum which replaces the notochord, a distinct head containing a brain which arises as an enlarged part of the nerve cord, and an internal usually bony skeleton and that includes some primitive forms (such as lampreys) in which the spinal column is absent and the notochord persists throughout life — Webster
Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata. Vertebrates include the jawless fish and the jawed vertebrates, which include the cartilaginous fishes (sharks, rays, and ratfish) and the bony fishes.
Extant vertebrates range in size from the frog species Paedophryne amauensis, at as little as 7.7 mm (0.30 in), to the blue whale, at up to 33 m (108 ft). Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. — Wikipedia

Researchers discover a system essential for limb...
on June 3, 2020 at 6:00 pm
Researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have discovered a system that provides cells with information about their position within developing organs. This system, studied in developing limbs, tells cells what anatomical structure they need to form within the organ. The article, published today in Science Advances, shows that malfunctioning of this system causes congenital malformations and could partly explain the effect of thalidomide, a drug […]
On the hunt for megafauna in North America
on June 2, 2020 at 2:42 pm
Research from Curtin University has found that pre-historic climate change does not explain the extinction of megafauna in North America at the end of the last Ice Age.
Out-evolving coronavirus by evolving our own...

If there is one thing that the coronavirus pandemic has exposed, it is that there is much that we still don't know about the world around us. Forget about the trillions—okay, more than trillions—of galaxies in the universe that we'll never explore. Just at our feet or in the air around us are cohabitants of our own world—viruses—that occupy an odd liminal space, pushing our understanding of the meaning of life. They exist in what is effectively a hidden world, almost a […]
Loss of land-based vertebrates is accelerating,...

In 2015, Stanford biologist Paul Ehrlich coauthored a study declaring the world's sixth mass extinction was underway. Five years later, Ehrlich and colleagues at other institutions have a grim update: the extinction rate is likely much higher than previously thought and is eroding nature's ability to provide vital services to people.
Emerald predators: Ohlone tiger beetles reclaim...

For the first time in over a decade, endangered Ohlone tiger beetles roam a preserve near Soquel and await their chance to pounce on unsuspecting prey. Their metallic emerald bodies appear iridescent in the sunlight as they scurry across the bare earth.
