Hey pal, You must know what's the featured article on Wikipedia, anon : The Wikipedia article of the day for November 6, 2017 is Rotating locomotion in living systems.
Rotating locomotion in living systems – the use of wheels and propellers by organisms – has long been pondered among biologists and writers of speculative fiction. Rolling and wheeled creatures have appeared in the legends of many cultures. While other human technologies, like wings and lenses, have common analogues in the natural world, and several species are able to roll, structures that propel by rotating relative to a fixed body are represented only by the corkscrew-like bacterial flagella. Macroscopic organisms have apparently never evolved wheels, and this is attributed to two main factors: limitations of evolutionary and developmental biology, and disadvantages of wheels, when compared with limbs, in many natural environments. Wheels, beyond the molecular scale, may not be within the reach of natural evolution, and may be infeasible to grow and maintain with biological processes. Compared with limbs, they are often less energy-efficient, less versatile, and less capable of traversing or avoiding obstacles. These environment-specific disadvantages of wheels also explain why some historical civilizations abandoned them.

Our new 'Word Of The Day' article update : Bolshevism , n :
The strategy used by the Bolsheviks in attempting to gain power in Russia. The Communist totalitarian political ideology adopted by the Russian Soviet Federative Socialist Republic and the Union of Soviet Socialist Republics; Marxism-Leninism. The 100th anniversary of the October Revolution (7–8 November 1917; 25–26 October in the Old Style calendar), which led to the rise of the Soviet Union, takes place this year.
