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

Study: The human lifespan is written into our DNA
on December 13, 2019 at 1:31 pm
Humans have a "natural" lifespan of around 38 years, according to a new method we have developed for estimating the lifespans of different species by analyzing their DNA.
Scientists devise 'lifespan clock'
on December 12, 2019 at 4:00 pm
An Australian research team say they have come up with a "lifespan clock" which provides accurate maximum age estimates for vertebrates, a key variable in the study of both living and extinct animals.
When flowers reached Australia
on December 12, 2019 at 2:21 pm
New research has revealed that Australia's oldest flowering plants are 126 million years old and may have resembled modern magnolias, buttercups and laurels.
Experiments in evolution
on December 12, 2019 at 1:11 pm
A new find from Patagonia sheds light on the evolution of large predatory dinosaurs. Features of the 8-meter-long specimen from the Middle Jurassic suggest that it records a phase of rapid diversification and evolutionary experimentation.
Mass extinction of land and sea biodiversity 250...

Some 250 million years ago, simultaneous mass extinctions of marine and terrestrial life occurred in an event known as the End-Permian. Or so scientists believed.
