- Gnathostomata (/ˌnæθoʊˈstɒmətə/; from Ancient Greek: γνάθος (gnathos) ‘jaw’ + στόμα (stoma) ‘mouth’) are the jawed vertebrates. Gnathostome diversity comprises roughly 60,000 species, which accounts for 99% of all living vertebrates, including humans. In addition to opposing jaws, living gnathostomes have true teeth (a characteristic which has subsequently been lost in some), paired appendages (pectoral and pelvic fins, arms, legs, wings, etc.), the elastomeric protein of elastin, and a horizontal semicircular canal of the inner ear, along with physiological and cellular anatomical characters such as the myelin sheaths of neurons, and an adaptive immune system that has the discrete lymphoid organs of spleen and thymus, and uses V(D)J recombination to create antigen recognition sites, rather than using genetic recombination in the variable lymphocyte receptor gene.
- What Makes Westerns so Cool? (YouTube)
The Western genre is one of the most recognisable genres out there, with many classics such as ‘Once Upon a Time in the West’ and ‘The Good, the Bad and the Ugly.’ When people think of classic films, no doubt Westerns spring to mind. But why are they so memorable? And why have they had such a lasting impact on popular culture and cinema as a whole? This video aims to answer this question by examining what makes them so cool, by focussing on Sergio Leone’s western filmography.
